One of the world’s biggest cities may be just months away from running out of water

Mexico City CNN —  Alejandro Gomez has been without proper running water for more than three months. Sometimes it comes on for an hour or two, but only a small trickle, barely enough to fill a couple of buckets. Then nothing for many days.

Gomez, who lives in Mexico City’s Tlalpan district, doesn’t have a big storage tank so can’t get water truck deliveries — there’s simply nowhere to store it. Instead, he and his family eke out what they can buy and store.

When they wash themselves, they capture the runoff to flush the toilet. It’s hard, he told CNN. “We need water, it’s essential for everything.”

Water shortages are not uncommon in this neighborhood, but this time feels different, Gomez said. “Right now, we are getting this hot weather. It’s even worse, things are more complicated.”

Mexico City, a sprawling metropolis of nearly 22 million people and one of the world’s biggest cities, is facing a severe water crisis as a tangle of problems — including geography, chaotic urban development, and leaky infrastructure — are compounded by the impacts of climate change.

Years of abnormally low rainfall, longer dry periods, and high temperatures have added stress to a water system already straining to cope with increased demand. Authorities have been forced to introduce significant restrictions on the water pumped from reservoirs.

“Several neighborhoods have suffered from a lack of water for weeks, and there are still four months left for the rains to start,” said Christian Domínguez Sarmiento, an atmospheric scientist at the National Autonomous University of Mexico (UNAM).

Politicians are downplaying any sense of crisis, but some experts say the situation has now reached such critical levels that Mexico City could be barreling towards “day zero” in a matter of months — where the taps run dry for huge swaths of the city.

Historic lows

Densely populated Mexico City stretches out across a high-altitude lake bed, around 7,300 feet above sea level. It was built on clay-rich soil — into which it is now sinking — and is prone to earthquakes and highly vulnerable to climate change. It’s perhaps one of the last places anyone would choose to build a megacity today.

The Aztecs chose this spot to build their city of Tenochtitlan in 1325, when it was a series of lakes. They built on an island, expanding the city outwards, constructing networks of canals and bridges to work with the water.

But when the Spanish arrived in the early 16th century, they tore down much of the city, drained the lakebed, filled in canals and ripped out forests. They saw “water as an enemy to overcome for the city to thrive,” said Jose Alfredo Ramirez, an architect and co-director of Groundlab, a design and policy research organization.

Their decision paved the way for many of Mexico City’s modern problems. Wetlands and rivers have been replaced with concrete and asphalt. In the rainy season, it floods. In the dry season, it’s parched.

Around 60% of Mexico City’s water comes from its underground aquifer, but this has been so over-extracted that the city is sinking at a frightening rate — around 20 inches a year, according to recent research. And the aquifer is not being replenished anywhere near fast enough. The rainwater rolls off the city’s hard, impermeable surfaces, rather than sinking into the ground.

The rest of the city’s water is pumped vast distances uphill from sources outside the city, in an incredibly inefficient process, during which around 40% of the water is lost through leaks.

The Cutzamala water system, a network of reservoirs, pumping stations, canals and tunnels, supplies about 25% of the water used by the Valley of Mexico, which includes Mexico City. But severe drought has taken its toll. Currently, at around 39% of capacity, it’s been languishing at a historic low.

“It’s almost half of the amount of water that we should have,” said Fabiola Sosa-Rodríguez, head of economic growth and environment at the Metropolitan Autonomous University in Mexico City.

In October, Conagua, the country’s national water commission, announced it would restrict water from Cutzamala by 8% “to ensure the supply of drinking water to the population given the severe drought.”

Just a few weeks later, officials significantly tightened restrictions, reducing the water supplied by the system by nearly 25%, blaming extreme weather conditions.

“Measures will have to be taken to be able to distribute the water that Cutzamala has over time, to ensure that it does not run out,” Germán Arturo Martínez Santoyo, the director general of Conagua, said in a statement at the time.

Around 60% of Mexico is experiencing moderate to exceptional drought, according to a February report. Nearly 90% of Mexico City is in severe drought — and it’s set to get worse with the start of the rainy season still months away.

“We are around the middle of the dry season with sustained temperature increases expected until April or May,” said June Garcia-Becerra, an assistant professor in engineering at the University of Northern British Columbia.

Natural climate variability heavily affects this part of Mexico. Three years of La Niña brought drought to the region, and then the arrival of El Niño last year helped deliver a painfully short rainy season that failed to replenish the reservoirs.

But the long-term trend of human-caused global warming hums in the background, fueling longer droughts and fiercer heat waves, as well as heavier rains when they do arrive.

“Climate change has made droughts increasingly severe due to the lack of water,” said UNAM’s Sarmiento. Added to this, high temperatures “have caused the water that is available in the Cutzamala system to evaporate,” she said.

Last summer saw brutal heat waves roil large parts of the country, which claimed at least 200 lives. These heat waves would have been “virtually impossible” without climate change, according to an analysis by scientists.

The climate impacts have collided with the growing pains of a fast-expanding city. As the population booms, experts say the centralized water system has not kept pace.

‘Day zero?’

The crisis has set up a fierce debate about whether the city will reach a “day zero,” where the Cutzamala system falls to such low levels that it will be unable to provide any water to the city’s residents.

Local media widely reported in early February that an official from a branch of Conagua said that without significant rain, “day zero” could arrive as early as June 26.

But authorities have since sought to assure residents there will be no day zero. In a press conference on February 14, Mexican President Andrés Manuel López Obrador said that work was underway to address the water problems. Mexico City’s mayor, Martí Batres Guadarrama, said in a recent press conference that reports of day zero were “fake news” spread by political opponents.

Conagua declined CNN’s interview requests and did not answer specific questions on the prospect of a day zero.

But many experts warn of a spiraling crisis. Mexico City could run out of water before the rainy season arrives if it carries on using it in the same way, Sosa-Rodríguez said. “It’s probable that we will face a day zero,” she added.

This doesn’t mean a complete collapse of the water system, she said, because the city isn’t dependent on just one source. It won’t be the same as when Cape Town in South Africa came perilously close to running totally dry in 2018 following a severe multi-year drought. “Some groups will still have water,” she said, “but most of the people won’t.”

Raúl Rodríguez Márquez, president of the non-profit Water Advisory Council, said he doesn’t believe the city will reach a day zero this year — but, he warned, it will if changes are not made.

“We are in a critical situation, and we could reach an extreme situation in the next few months,” he told CNN.

‘I don’t think anyone is prepared’

For nearly a decade, Sosa-Rodríguez said she has been warning officials of the danger of a day zero for Mexico City.

She said the solutions are clear: Better wastewater treatment would both increase water availability and decrease pollution, while rainwater harvesting systems could capture and treat the rain, and allow residents to reduce their reliance on the water network or water trucks by 30%.

Fixing leaks would make the system much more efficient and reduce the volume of water that has to be extracted from the aquifer. And nature-based solutions, such as restoring rivers and wetlands, would help provide and purify water, she said, with the added advantage of greening and cooling the city.

In a statement on its website, Conagua said it is undertaking a 3-year project to install, develop and improve water infrastructure to help the city cope with decreases in the Cutzamala system, including adding new wells and commissioning water treatment plants.

But in the meantime, tensions are rising as some residents are forced to cope with shortages, while others — often in the wealthier enclaves — remain mostly unaffected.

“There is a clear unequal access to water in the city and this is related to people’s income,” Sosa-Rodríguez said. While day zero might not be here yet for the whole of Mexico City, some neighborhoods have been grappling with it for years, she added.

Amanda Martínez, another resident of the city’s Tlalpan district, said for people here, water shortages are nothing new. She and her family often have to pay more than $100 for a tank of water from one of the city’s water trucks. But it’s getting worse. Sometimes more than two weeks can go by without water and she fears what may be coming, she told CNN.

“I don’t think anyone is prepared.”

India’s man-made water crisis threatens more cities

Chennai water crisis isn’t an isolated case. 21 cities are expected to run out of water

  • 200,000 Indians die every year because they don’t have a safe water supply.
  • In theory, India receives enough rain every year to meet the needs of over a billion people.
  • A rapidly urbanizing and developing India needs to drought-proof its cities and rationalize its farming.

One of India’s largest cities, Chennai, is dealing with a crippling crisis: It has run out of water. In the middle of a particularly hot summer, the four lakes that supply the capital of the southern state of Tamil Nadu have dried up; together they contain just 1 per cent of the volume they did last year. Residents don’t have enough water to drink, bathe or wash clothes. People are working from home; malls have closed their bathrooms; and restaurants have shut their doors.

The natural instinct is to blame the situation on climate change and, indeed, the last monsoon’s rains were especially weak. While that’s certainly played a role, however, Chennai’s is largely a man-made disaster — one that more Indian metropolises are soon to suffer no matter the weather.

According to a study by the federal government think tank Niti Aayog, 21 Indian cities will run out of groundwater by next year, including the capital New Delhi and the information technology hub of Bengaluru. Two hundred thousand Indians already die every year because they don’t have a safe water supply, the report said. A shocking 600 million people face “high to extreme” water stress.

As the world warms, the rains on which India depends have become erratic: They frequently fail to arrive on time, and they fall in a more disparate and unpredictable pattern.

– Mihir Sharma

That Chennai should have run dry first is instructive. Less than four years ago, the now drought-ridden city was inundated by devastating floods. Though located on a flood plain, the city had paved over the lakes and wetlands that might have helped the process of recharging the water table. As a result, heavy rains couldn’t percolate into aquifers under the city. Water pooled and surged aboveground. That reduced the resources available to deal with a crisis like this year’s.

Elsewhere, demand is the issue. In theory, India receives enough rain every year to meet the needs of over a billion people. According to the country’s Central Water Commission, it requires at most 3,000 billion cubic metres of water annually and receives 4,000 billion cubic metres of rain.

Inefficiency and misuse

But too much water is wasted thanks to inefficiency and misuse. The situation is particularly dire in India’s northwest, irrigated by the great rivers that rise in the Himalayas. Indians are taught to revere the “green revolution” of the 1970s, when the northwest became India’s granary thanks to canals and tube wells that pumped out groundwater. That revolution, however, has turned out to be unsustainable. In 2011, 245 billion cubic metres of water was withdrawn for irrigation — a quarter of the total groundwater depletion globally that year.

Northwestern states should be growing less water-intensive crops; areas in the east of the country that receive much more plentiful rainfall should take their place as the bread baskets of India. But shifting cultivation patterns around is politically problematic. Farmers in the northwest don’t just expect to continue to grow water-intensive crops, they also want free or subsidised power with which to run the tube wells that pump out their rapidly depleting groundwater.

limate change activists have long argued that water will be the political flashpoint of the 21st century. Water-stressed India will likely be one of the first places to test that theory. The state of Tamil Nadu complains that it doesn’t receive its fair share of the waters of the Cauvery River; recently, the authority that nominally manages the river accused the government of neighbouring Karnataka of holding onto water that it should have allowed to flow down to the Cauvery delta.

Things might get even testier up north, where more than a billion people depend upon rivers that rise in the Himalayas. Bangladesh and Pakistan feel that India is being stingy with river water. Indian strategists constantly worry that China will divert water from the Himalayan rivers that rise in Tibet to feed the thirst cities in its own north.

The floods in Chennai are a warning. As the world warms, the rains on which India depends have become erratic: They frequently fail to arrive on time, and they fall in a more disparate and unpredictable pattern. The country can no longer afford to waste its dwindling resources.

A rapidly urbanising and developing India needs to drought-proof its cities and rationalise its farming. Water-harvesting must be a priority, alongside mechanisms for groundwater replenishment. As it is, every summer is hotter and less bearable. If Indians run short of water as well, one of the world’s most populous nations could well become unlivable.

As groundwater level depletes, city stares at the bottom of well

Photo Courtesy: Mumbai Mirror

Citizens across the city are reporting about an alarming depletion of groundwater. Wells situated in private properties and temples are almost running dry, they say.

Experts claim that although Mumbai is blessed with abundant groundwater, the low levels in the wells could be due to the massive construction taking place in the city. There are about 6,000 construction sites in Greater Mumbai, each one digging deep piles into the ground for making basements.

The issue was sparked early this month on Parsi community chat groups with members reporting low water levels in the wells inside several fire temples across the city. The well is a crucial component in any fire temple without which no liturgical ceremonies can be performed.

Juhu resident and civic activist Zoru Bhathena said the sweet water well on his property generally has 5 feet to 7 feet of water around this time of the year.

“This year, it has plummeted to just 3 feet,” he told Mirror. “I asked the neighbours and friends in the locality, and they pointed to a huge construction site near my house where the ground had a deep excavation for a basement,” he said.

“Substantial water extraction accompanies basement construction impacting water resources in the area significantly,” he added.

Several other residents in Juhu too complained that there was hardly any water left in their borewells with rocks at the bottom visible.

Bhathena has written to the Principal Secretary, Environment & Climate Change, Maharashtra Water Resources Regulatory Authority and BMC commissioner regarding this.

The total water stocks in the seven lakes that supply water for Mumbai’s daily needs stood at 9 lakh million litres as on January 15 62% of the required quantum. On the same date last year, water stocks were at 9.59 lakh million litres or 66% of the required quantum which was also higher than this year’s situation.

In Thakur Complex, Kandivali (east), Nishant Mody said that they have seen a significant reduction in borewell water supply from January 9. Initially, residents suspected it was due to water leakage or a pump-related issue.

“We have had to increase our pump running time and reduce the water usage in the garden to compensate for this reduction. Our security personnel who also works in a nearby housing society, observed similar depletion around the same dates,” said Mody.

Structural experts and environmentalists Mirror spoke to said that they were not surprised. Alpa Sheth, a structural engineer, said that the proliferation of skyscrapers could be the reason. Most have 3-4 level basements.

“Mumbai is a city beside the sea and the water table is bound to be high. If so many construction sites are going to go below the ground and suck out the water, its effect will be seen somewhere,” she said.

Amar Joshi, a geologist, said that the rampant piling work that the city is witnessing could be a cause for depletion of ground water. “Besides, there are many infrastructure projects like the coastal road twin tunnel or the underground metro where digging is done several metres below the ground.

The groundwater that is sucked out is all wasted,” said Joshi. He added that borewells in areas like Dhobi Talao once catered to a much larger number of water tankers than at present.

Environmentalist Subhajit Mukherjee, founder of the NGO Mission Green Mumbai, said climate change could also be attributed as one of the factors to these complaints of depleting ground water levels. “Earlier, the rain pattern was such that through the four monsoon months, the city would receive continuous rain, allowing the water to soak in at ease. But now the situation is such that the city gets intense rain in a short spell, making up for all the four months.

This large quantum of rainwater cannot be soaked in easily, leading to a run-off,” said Mukherjee Bhagwan Kesbhat, founder of the NGO Waatavaran Foundation, who also worked as a programme coordinator with the NGO Paani Foundation, said that historically Mumbai has been known as the city of wells.

“The city was not dependent on outside water which now comes from the seven lakes situated outside the city limits. However, as the population grew, the need for these lakes was felt. Despite abundant rainfall, we have not taken advantage of it by harvesting rainwater. In the event of a bad monsoon, the water stress in Mumbai will be tremendous,” he said.

Recharge Before Groundwater Depletes

Photo Courtesy : The Interview World

NeeRain, an innovation-oriented startup, tackles the groundwater crisis through the use of local, decentralized rooftop rainwater filters. These filters empower individuals to lead water-secure lives. Furthermore, the startup holds patents for a range of rooftop rainwater filters that are both easy to use and cost-effective. Their goal is to harvest rooftop rainwater in every habitat.

Through extensive research, NeeRain’s team has achieved a technological breakthrough in rooftop rainwater filters. This advancement is bringing joy to millions of people worldwide by providing a sustainable solution to water scarcity.

As a young startup, NeeRain focuses on the cause of rooftop rainwater harvesting. They believe that the populace receives rooftop rainwater freely. However, much of it goes to waste. On this concept, NeeRain offers patented technologies to capture every drop of rainwater, allowing it in daily activities or diverting to recharge groundwater sources.

In an exclusive interaction with The Interview World, Naishal Shah, Co-founder and CEO of NeeRain Pvt. Ltd., emphasizes the startup’s mission to combat groundwater depletion. The company aims to achieve this by offering an affordable system to capture and redirect rainwater to aquifers. Here are key excerpts from his insightful interaction.

Q: What features does your rainwater harvesting system incorporate, and how does it contribute to the overall groundwater sustainability?

A: Rainwater is freely available during monsoon. However, the water we receive goes down to drains. Here, we provide a technology that enables people efficiently filter the rainwater and direct it towards the borewell or tank, eventually recharging groundwater. Our advanced technology employs a two-stage water filtration system. Once filtered, all the water can either enter the borewell or the tank. Remarkably, a 1000-square-foot roof can yield approximately 50,000 to 60,000 litres of water in just one rainy season in places like Delhi and Ahmedabad.

If we shift our focus to regions like Kerala or Mumbai, a 1000-square-foot roof has the potential to provide an impressive 2-3 lakh litres of water in a single rainy season. Currently, a significant portion of this water is either wasted, blocked, or eventually drains into rivers and seas. By implementing a simple filtration process, we can redirect this water directly into the borewell and tank, storing valuable rainwater. Furthermore, channeling rainwater through the borewell contributes to an increase in groundwater levels.

The water filtered through our system is exceptionally clean, and its introduction into the groundwater does not lead to deterioration. Notably, rainwater captured directly does not exhibit hardness or Total Dissolved Solids (TDS). Considering the alarming rise in groundwater depletion, directing rainwater to the groundwater directly presents a practical solution to elevate groundwater levels and address this urgent concern.

Q: What is the cost estimate for implementing a rainwater harvesting unit suitable for a 1000 sq. feet rooftop area?

A: The cost for our rainwater harvesting unit is Rs. 2950. One can complete any additional small and heavy plumbing work within a budget of Rs. 10,000. Our system boasts a lifespan of 10 years, and the maintenance is hassle-free with a simple filter removal and washing process, eliminating any recurring costs. You can easily manage this routine maintenance by hiring your local plumber, as no special technical skills are necessary for setting up our rainwater harvesting unit.

Having filed for a patent in 2018, we successfully obtained approval in 2020. To date, we have already installed over 10,000 units, actively promoting the importance of rainwater harvesting and groundwater recharge. We remain committed to spreading this message, encouraging more people to take an interest in sustainable water management. Remarkably, we have received zero complaints about the performance of our products.

Q: Can you provide supporting data or evidence to substantiate the claim that 30 crore liters of water have been saved over the course of the last 2 years?

A: Certainly, all the data is at our disposal, categorized by states and cities based on the deployment of rainwater harvesting units. For instance, in Delhi alone, where we’ve implemented these units, capturing 500 mm of rainfall during a season can result in saving a substantial 50,000 litres of water. We’ve meticulously collected data from households in Delhi, supporting our assertion with accurate figures.

As a result, the harvested rainwater ensures that clean water percolates into the ground, safeguarding water quality and preventing contamination in the process. This approach aligns with our commitment to sustainable water management.

Q: What underlying technology powers your system?

A: Our system operates based on gravity, eliminating the need for electric power or any additional mechanical devices. The system incorporates two-stage filters: a 400-micron net for the initial stage and a 200-micron net for the second stage. In the first stage, larger particulates are filtered, followed by the filtration of smaller particulates in the second stage. This sequential process ensures that the water entering the ground is thoroughly purified. As a result, your water resource remains untainted, and rainwater is effectively conserved.

Water Crisis In Pune : No Permission To New Building In PMRDA Without Assessment : Saurabh Rao

Photo Courtesy : Pune Pulse

Second meeting called by the Divisional Commissioner of Pune Saurabh Rao regarding the water crisis in PMC and PCMC was held today. More than 60 residents representing various organisations attended the meeting raising various issues.

Advocate Satya Muley shared important points that were discussed with Pune Pulse.

Important minutes of meeting

Divisional Commissioner of Pune announced in presence of PMRDA Commissioner that henceforth no new permissions shall be given in PMRDA jurisdiction without ascertaining availability and capability of local body/PMRDA/Zilla parishad to provide water to the new construction. No new construction permission shall be provided based on an affidavit taken from builders.

Almost 60 to 70 representatives of housing Societies, Housing Federations, Akhil Bharatiya Grahak Panchayat, Maharashtra Housing  societies federation were present.

The demand for providing water through tankers by PMC and PCMc was once again discussed and DC mentioned that the subject is being evaluated.

Spot visits to both corporations have been directed to understand the ground level realities and offer solutions.

Dedicated email id to be shared by both corporations to register complaints from housing complexes regarding water scarcity.

From the next meeting complaints to be received in advance and solutions to be offered during the next monthly meeting.

Adv Satya Muley stated that it is a district wide problem and intensive efforts by the special committee is required. Although providing immediate solutions to current scarcity is important, long term planning is also important which appears to be lacking by both the corporations.

Sunil Koloti, a resident of Nyati Windchimes who was part of the meeting stated that the meeting was fruitful but only it should turn into prompt action. 75 percent of our monthly maintenance goes into procuring water through tankers. PMC must come up with some solution now.

Another resident, Dilip Shah, founder of Undri Residents Forum said, “There were many residents who were present today.  We are hoping that strong action is taken by PMC as well as PCMC. It’s high time citizens get their due. Potable drinking water is what we are demanding. This meeting should not turn into another assurance but no result.”

Rain Water Harvesting- Solution to India’s Water crisis

Photo courtesy:Indiamart

India is facing the worst water crisis in its history. As per a report by Niti Ayog 21 cities in India will run out of groundwater by 2020. According to a report published by WaterAid around 80% of India’s surface water is polluted. A majority of the population is dependent on the groundwater which is again struggling to keep pace with the needs of the rising population.  While around 200,000 people are dying each year due to inadequate access to safe water, the situation will likely get worse as the population will increase.

While cities are grappling for water supply, there is an urgent need for improved measures to manage water resources. Water conservation and management are becoming a worldwide concern due to the accelerating water shortages, rapid development, population growth and growing agriculture. In such a situation, rainwater harvesting is a viable solution to help meet this demand and solve the water crisis to some extent.

A major population heavily depend on the municipality supplied water for daily household use. This growing reliance put an unnecessary burden on the infrastructure. Rain-water harvesting can save gallons of water for daily household or office use. For every 1000 sq feet of roof space, approximately 620 gallons of water can be saved every time it rains. This source of non-potable water can be used in flushing toilets, laundry etc. The saved water can fulfil at least 70% of the water demand in a household of 3 people during a drought year. If saved for months, this water can also be used for irrigation and fulfil the water requirement of crops in a drought-like situation. Further, if used with drip irrigation, more water can be saved and dependence on municipal water supplies can be reduced to a great extent.

Rainwater harvesting has been adopted by many countries as a viable means to save water. With the increasing population and dependence on water, it becomes pertinent for households to start investing in rain-water harvesting systems (RWH). Govt, both at the centre and state must take a proactive step towards making it mandatory for buildings and complexes to install Rainwater Harvesting System. A huge penalty should be imposed upon building without a proper urban water management system. Considering the huge water problem, monitoring and strict action against violation of the rules are equally important to deal with the crisis.

Water conservation also lies in the hands of Corporates and individuals. Corporate consciousness towards water and individual empathy can make a huge difference. With government mandating the socio good paradigm, the corporates now equally have the onus to implement low water usage methods and social welfare policies, aimed at water management and harvesting rainwater. Corporates within their capacity can design CSR initiatives concentrating on water conservation, rain-water harvesting and spread water awareness in the most interior parts of the country.

In order to save the country from the water crisis, social consciousness has to be practised at all levels. People have to come forward and realize their responsibility towards water and make sure we take proactive measures to ensure its effective management.

10 things you need to know about the water crisis in India

India is experiencing its worst ever water crisis. How did we get here?

News stories on India’s water crisis start peaking just as summer sets in. Images of wells and taps running dry, conflicts on drinking water, tankers being mobbed, parched earth, and failed crops dominate our news cycle. What’s missing in mainstream reporting is a comprehensive and informed understanding of what makes India’s water footprint both unique and challenging.

What underlies India’s insatiable thirst for water?

  1. India has a serious water problem

The 2030 Water Resources Group estimates that if we continue to consume water as per the current rate, India will have only half the water it needs by 2030—a flashpoint that’s only ten years away.

  1. Nearly 80 percent of India’s freshwater is used in agriculture

This is an unusually large water footprint for agriculture. China and South Africa use approximately 64 percent and 62 percent of their renewable freshwater resources for agriculture.

Groundwater accounts for 90 percent of the drinking water requirements in rural India and nearly 50 percent in urban areas.

  1. Over half of India’s cultivated land is under water-intensive crops

Fifty-four percent of India’s 141.4 million hectares of cultivable land is under water-intensive crops—rice, wheat, sugarcane, and cotton. Farmers are incentivised to grow water-intensive crops as they are eligible for the government’s minimum support price (MSP), which protects them from the risk of fluctuating prices.

  1. India uses at least twice the amount of water to grow one unit of food versus comparable countries

For instance, for every 1000 litres of water, China produces 0.46 kilograms of rice and 1.08 kilograms of cereal. For that amount of water, India produces only 0.23 kilograms of rice and 0.36 kilograms of cereal.

  1. India’s farmers rely mainly on tube wells to extract groundwater for their crops

Despite India’s large dams and canal systems, groundwater accounts for 63 percent of water used for irrigation by farmers; canals account for only 26 percent.

  1. Conservative estimates suggest that India has over 30 million borewells today

Until 1960, Indian farmers accessed a few tens of thousands of mechanical pumps using diesel or electricity to pump water. As of 2009, for every four cultivator households, one owned a tube well and two purchased groundwater from tube well owners. A combination of incentives (such as MSP for water-intensive crops) and subsidies (such as free electricity) have encouraged large-scale extraction of groundwater.

  1. India draws nearly 25 percent of the world’s groundwater

That’s more groundwater than China and the United States combined. India withdraws two times the amount of groundwater compared to China, despite having a similar population size.

Photo courtesy: Indiamart

  1. Sixty percent of India’s districts have been declared critical on groundwater

This means that they either have scarce supply or poor quality of groundwater, or both. This has put 70 percent of rural households who depend on agriculture for their livelihood at risk.

  1. India’s depleting groundwater reserves also impact our drinking water

Groundwater accounts for 90 percent of the drinking water requirements in rural India and nearly 50 percent in urban areas. Excessive extraction has caused contamination. As a result, India is ranked 120 out of 122 countries in the global water quality index.

  1. The country’s water crisis has a significant economic cost

A NITI Aayog report suggests that severe water scarcity will eventually lead to a 6 percent loss in the country’s GDP.

For too long, we’ve taken a supply lens to address issues related to water, within a development paradigm that has focused on building infrastructure, such as dams, canals, minor irrigation structures, and now water pipes. India’s water story starts and ends in her farms. What India needs now is a movement to help her farmers use water judiciously for every unit of food that they grow. This holds the key to a water-secure future for the country and an end to stories of distress that mark each summer.

A deeper look into the roots of Water Crisis in India

Introduction to Water Scarcity

The issue of water scarcity is a global problem. The unequal distribution of water resources, and the great demand of freshwater globally has led to what the World Economic Forum calls as one of the largest global risks in terms of potential impact over the next decade in 2019. The increase in demand for freshwater is a result of, but not limited to, the increasing world population, changes in consumption, and industrial demands. Further, the great inequity between the developed and developing countries, in terms of water resources, grows larger as drinking water and water usage is becoming privatized and coupled with economic growth. This has led to Lower Economically Developed Countries (LEDCs) to lose opportunities to gain water shifting government priorities.

The issue of water scarcity is best seen from the perspective of India, a crisis which affects approximately 1 million people a year. The water crisis playing out in India today can be seen as a microcosm of the overall situation that will, or already has, affected many countries in the world. Private water tank owners illegally smuggle and sell clean water at expensive prices, greatly exacerbating the issues of the water crisis in the first place. That, coupled with infrastructural issues and climate change, the issue of water scarcity in India is surely important to examine. This blog seeks to examine the causes of water scarcity in India, the effects it has on the population, and the possible solutions that already exist and/or should be implemented at a local and a national level.

Causes for the Water Crisis in India

The two major monsoons in India, the North-East and the South-West monsoons, account for a large proportion of water that can be harvested and distributed. However, as a result of climate change, monsoons are being disrupted and losing a lot of water.

According to the India Meteorological Department in 2018, the North-East monsoon was deficient by 44% while the South-West monsoon fell short by 10%. Lower rainfall has reduced water levels by about 32% in 91 major reservoirs across the country.

As stated by Impakter, “Unusual temperatures caused by climate change have made rainfall erratic with significant changes in monsoon patterns making droughts and floods more common in many parts of India.”

Causes for the Water Crisis in India

The rapid urbanization of India coupled with a lack of city planning has led for former ponds to be used up due to the rising population and a general lack of infrastructure used to treat wastewater for reuse nor an appropriate method of collecting and distributing water.

According to the Central Water Commission, the country still receives enough rainfall to meet the needs of over 1 billion people. Yet, due to poor city planning and the growing population, India only catches only 8 percent through inefficient rainwater harvesting.

Effects of the Water Crisis in India

The water crisis in India affects hundreds of millions of people. Though a lot of Indians are capable of purchasing drinking water from private distributors, rural Indians are faced with walking kilometers away to reach a well or public water pump. Indians who are unable to purchase water are forced to dig bore wells, especially in times of crisis.

First, in June 2016, Latur faced the depletion of approximately 90% of water sources. Next, in 2019, Chennai completely depleted its water supply on the 19th of June, because of deficient rainfall in the previous year’s monsoons.

The vibrant ecosystems of India, and the lives of the indigenous flora and fauna, are threatened by this lack of water. In 2016, the Indian cities of Mettur and Kolathur, in the face of a drought, saw wild animals like elephants, tigers, and deers sneaking into the city in search of water. Indian gaurs in Madurai, Tamil Nadu wound up dead as they fell into wells in search of water.

Agriculture makes up about 16% of India’s economy, according to the World Bank in 2019, and employs almost 44% of India’s working population. In the absence of water, farmers wouldn’t be able to produce crops. This causes much of the farming industry in India to cease operations, collapsing the local economies of smaller Indian towns. This has led farmers and other workers in the agricultural sector to move out into cities in search for jobs. However, this increases the demand for water in major cities, and further complicates the strain that major Indian cities have on the scarce supply of water

Efforts to the Water Crisis

The Government of India has established a new ministry and launched cleaning programs in order to increase the whole country’s water use efficiency. Firstly, the Jal Shakti ministry was formed by Prime Minister Narendra Modi in June 2019. It combines the Ministry of Water Resources, River Development and Ganga Rejuvenation, with the previous Ministry of Drinking Water and Sanitation to form a specialized ministry to clean the river Ganges, settle international water disputes, and provide safe drinking water to the people of India. The Ganga Action Plan was started in 1985 to tackle the problem of water pollution in the river Ganges, however government incompetence hindered the action plan to be anywhere close to efficient. Prime Minister Narendra Modi announced that his government would be investing more into managing the pollution of the various rivers in India.

Non Government Organizations (NGOs) like ‘FORCE’ and ‘Safe Water Network’, along with international organizations such as ‘We are Water’ and UNICEF are actively working to provide water supply and sanitation to villages and dealing with the overall water crisis in India. One way NGOs help is by raising social awareness of these issues. Many smaller NGOs use social media, advertising campaigns, and engaging with local people in order to educate how to manage water efficiently at a local level. For example, ‘We are Water’ publishes documentary films every year to raise social awareness on the severe water scarcity issues of India, along with other countries’ scarcity issues as well. Another way NGOs help is by creating Water Resources Projects. For example, UNICEF supported the creation of a 1000+ hectare catchment plan near Ahmednagar, Maharashtra strictly for domestic usage. The Jal Bhagirathi Foundation is prominent in Rajasthan for covering over 550 villages and reviving more than 2000 water harvesting resources in the region.

Possible Solutions

As technology improves, new innovations allow ways to manage water resources more effectively, and possibly solve the water crisis in India. One such technology is rainwater harvesting. A lot of homes already, in India, have rainwater harvesting structures in order to be self sufficient. In Banglore, Biome Environmental Trust and Friends of Lakes dug upto 1 million of these rainwater harvesting wells and connected them to the groundwater, collecting about 60% of total rainwater in the region. Desalination, or the process of treating sea water to make it fit for drinking, is a technique that can solve the problem of water shortages, especially in coastal cities. Israel has already utilized desalination for industrial and domestic use. The Indian government is already looking into desalination technologies, especially for coastal cities like Chennai. Another technology used to manage water resources is the smart water meter. WEGoT, our startup company in India, has innovated on the old analogue design of a water meter and created a new product that uses ultrasonic sensors to monitor water flow with more than 98% accuracy accompanied with a digital app to monitor your water usage intuitively with a simple UI. The installation and usage of this technology is seamless and can greatly benefit both the common customer and larger organizations who wish to manage their water consumption. Finally, irrigation techniques such as drip irrigation technology efficiently controls the amount of water to land and can possibly relieve the water scarcity in India for decades.

Conclusion

The issue of water scarcity in India already has long reaching effects, some of which can already be seen today. Although some factors, such as city planning, cannot be immediately changed to solve this problem, new technologies can definitely help alleviate and possibly reduce the intensity of this issue in India. Though the government of India is finally investing more resources into solving this problem, it’ll take the cumulative effort of every single Indian citizen to conserve their own water, and the effort of the government to implement costly, yet effective, technology and infrastructure to distribute water evenly throughout the country. And with hope, this issue can be finally solved and put to rest.

49 billion liters of water is wasted daily in the country due to carelessness

There has been a demand for provision of stringent penalties to prevent wastage of water. Clean water is not being provided to 16 crore people in the country.

33% of people in India keep the tap open even without work while bathing and brushing, which leads to wastage of clean water. An estimate of water wastage is that every day 4,84,20,000 crore cubic meters i.e. 48.42 billion one liter bottles of water is wasted, while in this country about 160 million people do not get clean and fresh water. At the same time, 600 million people are facing water crisis. After taking note of these facts in a petition, the National Green Tribunal (NGT) has asked the Union Ministry of Jal Shakti to submit a factual account of wastage of water.

On behalf of NGO Friends, petitioner Rajendra Tyagi has filed this petition in NGT. The petitioner demands that there should be punishment for the wastage of water. There is no provision for this as of now. On the petition, a bench headed by Justice Adarsh ​​Kumar Goel, in its order, has asked the Union Jal Shakti Ministry as well as the Delhi Jal Board to file a report within a month.

There are many other reasons for wastage of water such as overflow of water from the tank in residential and commercial houses. At the same time, the flushing system is another major reason for wastage of fresh water. 15 to 16 liters of water gets wasted once the flush is run.

According to advocate Akash Vashisht, every third person in India leaves the tap running, wasting five liters of water a minute, while a shower wastes 10 liters per minute. About 25 liters of water is wasted during brushing for three to five minutes, while 50 liters is wasted during a shower of 15 to 20 minutes. Similarly, 20 to 60 liters of water is wasted while washing dishes.

Very deep borewells are also being installed in rural areas. While there is hand-pump and tubewell for drinking water. There is also no restriction on the use of water. Apart from this, there is a lot of wastage of clean water even during the washing of cars. Water demand in India will reach 220 billion liters by 2025 from 40 billion liters now. The NGT will now hear the matter after the ministry’s report.

Water crisis can be overcome by open well recharge system, Kerala became an example

Climate change is one of the many factors responsible for Kerala’s depleting groundwater levels, but to combat it, Anand Jakarayas, Development Associate (Water), MS Swaminathan Research Foundation, explains how open well recharge systems can help Kerala overcome the water crisis. helping. The open well recharge system is superior to other methods, as experiments have shown that scraping off the top sediment layer and 15 cm of topsoil can restore up to 68.3 percent of the initial infiltration capacity. Sometimes aquifers contain clay lenses, if the recharge water has high total dissolved solids (TDS) or high sodium concentration, the clay lens may move through the thick layers of the aquifer with groundwater, pumped from wells. The water used will be dirty.

In terms of cost and effectiveness, the cost seems to be low compared to artificial open well recharge systems and other water recharge systems. Methods based on surface infiltration have relatively low construction costs and are easy to operate and maintain. However, surface infiltration systems are not always suitable. This is not possible where permeable surface soil is not available, land is very expensive or there is poor-quality water on top of aquifers.

Direct subsurface recharge methods reach deeper aquifers and require less space than direct surface recharge. However, they are expensive to manufacture and maintain. Recharge wells, commonly called injection wells, are commonly used to replenish groundwater. This is done when the aquifer is deep and usually separated from the land surface by materials of low permeability.

In areas where the base flow of streams is supported by groundwater, adding storage for recharge and groundwater flow can result in higher sustained flows during low flows or drought conditions. The flow of the springs can be maintained at a high level even during summer through groundwater that would result from artificial recharge. On the other hand, surface reservoirs whose water quality has been reduced by low-quality water released from the aquifer can harm the ecology of the surface reservoir.

Cultural factors should also be taken into account when finalizing the type of recharge structure method and the location of the structure. Land availability, land use in surrounding areas, public attitudes, and legal requirements all contribute significantly to the successful implementation of an artificial recharge system. For example, in urban areas, injection wells with controlled water supply are preferred.

There are many benefits of open-well recharge system. It increases the availability of groundwater and groundwater table and is effective in all ecosystems across Kerala. Moreover, this technology helps in improving the quantity as well as quality of water in aquifers in rural areas.

Broadly speaking, the biggest reason for the continuous depleting groundwater level is the increase in the number of borewells. Salinity increases especially during the summer season as the groundwater level drops below mean sea level, facilitating lateral or vertical movement of salt water. As a result of this action, this salty water can enter the groundwater reservoirs. Similarly, the rivers of Kerala often face salinity intrusion in their lower reaches during the summer months when the flow of fresh water is reduced. The monsoon usually recharges the groundwater table sufficiently, leading to a low concentration of saltwater in the aquifers.

Kerala has a distinctive coastal aquifer system which is prone to saltwater intrusion into groundwater sources including wells. A rise in the sea level or a fall in the groundwater level or a change in tide or breaking of aquifers, etc., can lead to saltwater entering the wells. Around 50 wells in Poovar in Kerala alone have been affected by saltwater encroachment. Due to salty water, some people in rural areas are forced to resort to water pipelines, which are more expensive for them. Destruction of freshwater lakes and conversion of wetlands contribute to the decline in groundwater levels. The rising sea level due to global climate change is one of the reasons directly affecting this problem.

In Kerala, groundwater salinity is due to leaching of salts from aquifer material, not seawater intrusion. This is due to the fact that groundwater aquifers are mostly confined in Kerala which restrict direct seawater intrusion, and this is the reason why no seawater ingress into coastal waterways due to over-extraction has been reported from the Kerala coast. Is. However, salinity is observed in shallow wells that are close to backwaters, lagoons, lakes and tidal rivers. The coastal wells located at Kadalundi and Kottakkal are partly influenced by lagoon and partly by seawater as they have sea on one side and lagoon/backwater on the other. This problem is also found in places like Vadakara, Thiruvangur Beypore, Kozhikode beach, etc.

The presence of salt water in wells is an indicator of groundwater quality. Sodium chloride (AcCl) or common salt is the major salt found in groundwater, followed by magnesium chloride (MgCl). Some groundwater also enters surface water bodies such as canals, lakes, or streams, thereby altering the hydrology of surface water. The brackish water cannot be used for paddy cultivation which is a major economic activity of Kerala. The intrusion of salinity into groundwater mainly affects the supply for agricultural, industrial and domestic use. Due to the fall in the groundwater level, more and more borewells have to be dug, as a result of which the efficiency of the pumps is also decreasing. In addition, poor households in rural areas spend about two hours a day fetching water.
