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

Posted on

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

Posted on

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.

Recharge Before Groundwater Depletes

Posted on

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

Posted on

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.”

Rainwater Harvesting: A Viable Means To Prevent Water Crisis

Posted on

Photo courtesy:Istock

“Water, water, every where, / Nor any drop to drink”

These all too familiar lines from the poem by Samuel Taylor Coleridge seem to be ringing too close to home as water becomes an increasingly scarce resource with every passing day.

Water Crisis was ranked as the #5 Global Risk in terms of impact on society by the World Economic Forum in January 2020, making it an alarming issue requiring an earnest redressal. What is interesting is that it is not really about scarcity, but rather proper water management. To quote the World Water Council, “There is a water crisis today. But the crisis is not about having too little water to satisfy our needs. The crisis is managing water so badly that billions of people — and the environment — suffer badly.”1

For sustainability, a healthy relationship between natural cycles and the available natural resources is a must. To further this objective and protect the existing reservoirs, rivers, aquifers, and ecosystems from further destruction, one needs to harness the largest and most accessible resource currently going down the drain: Rain.

What is noteworthy is that harnessing rain neither requires no energy nor any natural resource; on the contrary, it helps preserve the much-needed fast depleting resource: Water.

Rainwater harvesting is an ancient concept that is simple to implement and scalable. Simply put, it is the act of collecting rainwater and storing it for later use.

Rainwater harvesting systems have many an avatar, from the basic rain barrels to collect rainwater to more intricate structures with pumps, tanks, and purification systems.

Rainwater collected through any system is fit for reuse. Without filtration and purification, it finds use in most functions minus consumption — e.g., flushing toilets, washing cars, irrigation etc. Once put through the purification process, it is fit for consumption as well.

In urban areas, the rain falls on roofs, buildings, roads, and other impenetrable hard surfaces, resulting in urban flooding giving rise to another set of challenges. This makes rainwater harvesting even more essential and advantageous. Urban flooding on one hand, and increasing water shortage on the other, is the driving force behind government norms to inculcate the culture of rainwater harvesting in more and more cities.

Let us take the case of Mexico City as an example. It is a city with one of the highest demands for water in the world. Today it is plagued by drying aquifers, the city to sink to the earth by 50 centimeters per year. Today it is estimated that while a large volume is lost every way on account of leaking water pipes across the water management system, heavy rains cause heavy flooding that leaves substantial damage behind every occurrence.2 Researchers confirm that if the city was to adopt an effective rainwater harvesting system, 60 percent of the city’s water needs could be met.3 In light of this, Isla Urbana, a local non-profit, has installed 20,399 rainwater harvesting systems from 2009 to date. The systems have recorded a harvest of 815 million liters annually.4 Mexico City’s water authority, SACMEX, has also installed rainwater harvesting systems in 85 schools in the Tlalpan and Alvaro Obregón boroughs.

Likewise, India — a country that can collect up to 1,000 liters of water or even more during the heavy monsoons — has shown a similar response. In the southern state of Kerala, the government has recently constructed around 87,000 rainwater harvesting pits across schools, offices, and residences,5 with the expectation of these pits to last up to five years, with minimum maintenance.

Following the trend, Singapore installed a rainwater harvesting system on the roof of a 15-story skyscraper. The system diverts the rainwater collected on the roof to two rainwater tanks. This water is supplied to the building’s toilets, with no processing or treatment — a demonstration of how a project like this can be successfully implemented in metropolitan cities such as New York with countless high-rises to cater to their equally high water demands (981 million gallons consumption per day, as of 20206).

But New York is hardly a city to miss out on the ongoing trends. NYC’s Department of Environmental Protection recently initiated a Rain Barrel Giveaway Program as part of their $2.4 billion Green Infrastructure Plan. Its objective is to encourage citizens to capture stormwater before it flows into the sewer system. The intention being to reduce sewer overflows into local waterways by 2030.

The world is slowly but surely waking up to the fact that rainwater harvesting systems need to be an essential part of the infrastructure. Irrespective of the intricacies, all rainwater harvesting systems require five fundamental components:

Catchment – The surface to collect rainwater. It could be a rooftop, a paved flooring surface, or a landscaped region. The volume of water you harvest is a function of the surface area of the catchment.

Gutters and conduit Pipes – They are responsible for directing the water to the storage tank. The most widely used materials for these are half-round pipes made of galvanized iron (GI), steel, aluminum, and uPVC, with GI, steel, and aluminum being the preferred options. Lead and other metal gutters (GI and steel) are not a wise choice for potable water systems. The slightly acidic quality of rain can dissolve lead and other heavy metal contained in gutter solders, contaminating the water supply.

The safest option to get the most usable rainwater is uPVC Pipes. They deliver faithfully on the promise of:

  • water with no harmful metals lacing it;
  • no leakages on account of corrosion over the years;
  • their almost frictionless surface allows for the maximum quantity of water to flow to the storage system;
  • their lighter weight allows for installation virtually anywhere.

Filters and first flush devices – Investing in the correct filtration device is a must. The filtration system should be one that can effectively remove harmful and polluting contaminants. A first flush valve flushes out the first spell of rain, which carries relatively more toxins from the catchment surface and air.

Storage tanks – An important component of the system. Depending on the space availability, they can be overhead, underground, or stacked. Common materials used for these tanks are poly, galvanized steel, and concrete. If the tank is above ground, measures to prevent algae growth will be needed.

Delivery systems – Piping systems that deliver the stored and filtered rainwater until the point of use. The material of pipes used for this purpose is the same as that of conduit pipes. uPVC pipes present the best option to deliver quality water consistently over the years. With 50+ years of life, no rust, no

corrosion, no heavy metals, and an almost frictionless surface, they offer a perfect solution. High-quality uPVC pipes assure you of a leak-free, durable, and minimal maintenance delivery system.

While building a rainwater harvesting system or incorporating it in a facility, it is crucial to be careful while choosing the components for the solution. It is crucial to pick the right materials. The choice at this stage will define the efficacy of the solution and yield the desired results. Rainwater harvesting, if done right, can help the world tide over the water crisis, allowing us to leave a more beautiful world for your future generations.

Making India water-secure: Solutions for the future

Posted on

‘Water, water everywhere and not a drop to drink’ – this predicament of the sailors in Samuel Taylor Coleridge’s famous poem is a portent to our collective futures; one with little to no access to safe water. In 2019, Chennai, a city that receives twice London’s average annual rainfall at 1,400 mm, had to meet its water needs by trucking in 10 million liters of water a day. The 2018 drinking water crisis in ‘Queen of Hills’ Shimla made international headlines when policemen were deployed on the ground to manage water distribution.

The NITI Aayog’s 2018 Composite Water Management Index (CWMI) depicts an unsettling picture of macro-water availability in India – despite being home to 17% of the world’s population, it has only 4% of the world’s freshwater resources. The total water demand in India is projected to increase by 22% and 32% in 2025 and 2050 respectively and, by 2050, 85% of this demand is expected to come from industrial and domestic sectors alone. Among the regions, the south and the northwest  are expected to face the worst in next two years. About two lakh people die every year due to inadequate water, sanitation and hygiene and ~820 million Indians living in twelve river basins across the country have per capita water availability close to or lower than 1000m3, the official threshold for water scarcity as per the Falkenmark Index.

To address this looming water crisis and ensure water security, it is imperative to devise a holistic urban water management system that can help balance biodiversity by protecting and restoring the health of waterways and wetlands, mitigate flood risk and damage, provide for sustainable and resilient communities, promote sustainable development goals (SDGs), and address the needs of the last person in the queue.

Some of the solutions available to this end include:

  1. Rejuvenation / conservation of water bodies: Replenishing and restoring the health of natural water bodies and wetlands is the single-most effective way of securing a safe source of water. Cities, like Bengaluru, have 210 lakes, covering 3,622 acres with a capacity of 35,000 million ft3. Long-term efforts such as Namami Gange are also bearing fruits. However, for more localized solutions, it is important that traditional water storage structures such as vavsand baolis are rejuvenated and maintained.
  2. Rainwater harvesting: India receives bountiful rains – last Monsoon, India received 925 mm rainfall in just four months. A part of the immense potential to create sources of water through rainwater harvesting is being realized – as on February 2, 2023, more than 1.19 million water conservation and rainwater harvesting structures have been constructed across India.
  3. Government initiatives: In the past few years, the progress towards providing piped water supply and last-mile delivery of water has been stupendous. The one-of-its-kind Jal Jeevan Mission supplied tap water to 10.64 crore – 55% – households in rural India until November 2022 and more than 15 lakh women were trained for testing water quality through field test kits.
  4. Digital interventions: Technologies such as artificial intelligence, machine learning, and Internet of Things (IoT) can help in flood prediction, rain forecasting, detecting water leakages, treating wastewater and harvesting rainwater. AI tools are capable of analyzing the data from recycling plants and suggesting ways to reduce energy consumption up to 30%, contributing to overall sustainable practices.
  5. Stemming groundwater depletion: Since agriculture utilizes the majority of groundwater, the World Bank has been supporting innovative projects targeted at the agrarian communities. These include Atal Bhujal Yojana, the world’s largest community-led groundwater management program and Paani Bachao, Paisa Kamao in Punjab that resulted in water savings between 6 and 25% without any adverse effect on the yield. With states like West Bengal, Jharkhand, Bihar, Assam and Manipur among others reporting high levels of arsenic in the groundwater, efforts for decontamination would also have to become part of the plan.

There is no doubt that the problem of water scarcity is one of environment, population, governance, health and well-being. Having to walk long distances and stand in long lines every day, 163 million people across the country continue to live without clean water close to their homes and ~0.2 million people die every year due to inadequate water, sanitation and hygiene. The population concentration is disproportionately high in Indian cities, 30 of which, according to the World Wide Fund for Nature (WWF), stare at a grave water risk.

Given the seriousness and complexity of the problem, policymakers must therefore employ systems thinking – an approach that can create an ecosystem for innovation that develops big-picture perspective, focuses on opportunities in a problem, and fosters adaptation amid rapidly-evolving environments. There is no doubt that greater involvement of communities can heavily alter the outcome of urban water management solutions. At the same time, funding such programs can meet a roadblock, especially in the wake of the devastating impacts of the pandemic. Therefore, fostering public-private partnerships (PPP) that can work by engaging communities, funders, corporate stakeholders and creating awareness will play a critical role in achieving the goal ahead.

Rain Water Harvesting- Solution to India’s Water crisis

Posted on

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.

Five environmental entrepreneurs making money sustainably

Posted on

An underlying theme of sustainable businesses is innovation – through either a product, service or a combination of both. Here are five environmental entrepreneurs saving the environment and promoting sustainability through their startups.

Many entrepreneurs today are setting up sustainable businesses that solve environmental problems and still make money because that’s the only way to keep any enterprise going.

An underlying theme of sustainable businesses is innovation – through either a product or a service or a combination of both. Environmental entrepreneurs solve the pressing problem of saving the environment and aiding ecological balance.

Here are five entrepreneurs who are contributing immensely to the cause of the environment through their unique products:

1. Nitin Sharma, Go Waterless, Pune

Water scarcity left Nitin’s family car wash business high and dry in 2016. After the problem continued well into 2017, Nitin began to research products that could wash cars without water.

Finally, in 2019, he developed eco-friendly high-lubricity sprays that clean car interiors and exteriors without water. Go Waterless has been profitable since its inception in 2019 and is present in 22 states.

More importantly, it is saving 12 lakh liters of water daily and earning Rs 2.5 crore in annual revenues.

2. Ashvin Patil and Chaitanya Korgaonkar, Biofuels Junction, Mumbai

Ashvin is an MBA and engineer who quit his job as an equity market analyst to set up Biofuels with his friend Chaitanya.

The duo started Biofuels in 2018 with the dual aim of solving farmers’ problem of agri waste disposal and providing clean fuel to enterprises. Most farmers, after harvest, burn residues like rice stubble, cotton stalks, and coconut husks, causing pollution.

Biofuels procures agri waste from farmers and it is then processed into solid biofuels at the nearest manufacturing facility in the startup’s network. The company’s field staff monitors the quality and consistency of biofuels, which replace coal, diesel and furnace oil at industrial plants, reducing the burden on non-renewable resources.

The sustainable startup works with 25,000 farmers and over 100 top companies. In just four years of launch, it is clocking Rs67 crore in annual revenues.

3. Amit Doshi, NeeRain, Ahmedabad

When Amit Doshi was in class four, he and his brother would accompany their mother to fill water from a tap near their house in Kalol, about 35km from Ahmedabad in Gujarat. The area’s borewells had dried up and the municipality supplied water every three days.

Growing up with water scarcity instilled in Amit a sense of purpose – to save every drop of water. One way to do it was through rainwater harvesting by collecting and storing rainwater that runs off from rooftops, roads, grounds, etc.

After a year of research and development, he designed an instrument to help people collect rainwater, which could be used to recharge borewells or stored, and named it NeeRain Rainwater Filter. This small filter unit with dimensions of 1x1x1.5 feet uses an engineering material called ABS (Acrylonitrile Butadiene Styrene), and it was patented in 2018. Amit’s startup earns Rs 2 crore in revenues annually and is growing rapidly.

4. Vinayakumar Balakrishnan: Thooshan, Kochi

Having spent a large part of his life working in leadership roles in the banking and insurance sector, Vinayakumar decided to return from Dubai to India in 2013 and began research on food waste that could be used to make biodegradable plates.

He approached the Council of Scientific & Industrial Research (CSIR)’s National Institute for Interdisciplinary Science and Technology (NIIST) in Thiruvananthapuram and funded the research on making biodegradable food plates from rice bran. Once the technology was in place, he set up a fully integrated robotic plant in Kochi to make biodegradable cutlery and Thooshan went live in 2021.

According to estimates, producing just one pound of plastic cutlery can take up to 78 liters of water and release 2.5 lbs (1.1 kg) of carbon dioxide. This plastic is difficult to recycle and ends up choking animals and polluting water bodies and soil.

Thooshan cutlery can be decomposed into organic manure or can be used as cattle feed, fish feed, or poultry feed. The startup is sustainable and environment-friendly.

5. Bhavini Parikh, Bunko Junko, Mumbai

In 2016, while working on her garment manufacturing business, Bhavini came across research that textile waste is the third largest source of municipal solid waste in India. With landfills having a limited capacity to take on the load, she decided to minimize fabric waste at her level.

“I realized I was also hurting the environment by being part of the fashion industry. So I thought of up-cycling fabric scraps produced in my garment manufacturing unit,” she says.

Today, her ethical fashion brand Bunko Junko turns textile scrap into stylish clothing, home furnishings, and accessories. Since 2018, it has saved 38 tonnes of fabric from going to landfills and empowered thousands of women. And her profitable operations clock Rs. 40 lakh in revenues annually.

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

Posted on

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.

  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.
