A city in India almost ran dry. What will prevent a repeat?
After water-supply scares this summer, Chennai is welcoming fall rains. But residents worry better planning is needed to avoid long-term water issues.
After water-supply scares this summer, Chennai is welcoming fall rains. But residents worry better planning is needed to avoid long-term water issues.
On a sultry September afternoon Eswari meanders restlessly around her neighborhood. Dressed in a floral printed nightgown and her hair tied in a messy bun, she halts occasionally to exchange a few words with passersby. At one moment, she joins a group of women who look at the gray clouds gathering overhead and release a collective sigh. There is only one topic of discussion here: water.
Eswari works as a security guard at an IT firm, but today she took leave. She wanted to ensure she would be available to fill the two large water drums that her family uses for everything except drinking and cooking, on the odd chance water came through the pumps outside their building. It did not.聽
鈥淲e are not informed which day or time water will be supplied next,鈥 says Eswari, who uses only one name. For the past two months, she says, the average gap has been about six days. 鈥淚 think it will be supplied tomorrow. I鈥檒l ask my daughter to skip school and fill the drums.鈥澛
In June, this southern Indian city of 10 million grabbed international headlines for nearing 鈥淒ay Zero鈥: almost running out of water, in other words. Of Chennai鈥檚 four main reservoirs, three had gone completely dry聽鈥 and the last, Poondi, had 26 million cubic feet of water, against its full capacity of 3,231 million cubic feet.聽
Now, as late-fall rains finally arrive, many are breathing a sigh of relief. But long term, the water situation here and in many other Indian cities is exacerbated by poor management and rapid development, observers say, leaving many poorer residents feeling like they must fend for themselves.
鈥淢anaging the demand for water for a growing population in the country is a major challenge,鈥 says Kangkanika Neog, an analyst at the Council on Energy, Environment and Water, a Delhi-based think tank. 鈥淭here are existing gaps like poor water quality due to lack of proper monitoring and low treatment capacity, inefficiency in the supply of water, and groundwater depletion. ... Climate change is only making things worse.鈥
鈥淚t鈥檚 time for institutions to come together and look at water as an integrated component during urban planning,鈥 Ms. Neog adds. 鈥淭he infrastructure of old cities was based on the scenario of water plenty but that鈥檚 no longer the case.鈥
Six hundred million people across the country face high to extreme water stress. According to a recent report by World Resources Institute, a U.S.-based think tank, India is the 13th most water-stressed country in the world聽鈥 but has triple the population of the other 17 worst-affected countries combined. Another report, released by India鈥檚 Central Water Commission, observes that scarcity is a result not so much of water deficit as of 鈥渟evere neglect鈥 and lack of monitoring.
Waiting for water
Over the summer, as taps ran dry, about 900 city tankers supplied water to Chennai, but at an irregular schedule. Tankers source most of their water from agricultural wells and farms in the outskirts of the city, however, draining farmers and rural residents to meet urban needs and further depleting groundwater in the process. Chennai is overdrawing its groundwater by 185%.聽
For those who can afford it, there are about 5,000 private tankers, and for a while, even special trains were arranged to carry water. At the crisis鈥檚 peak, the chief minister of Tamil Nadu state, of which Chennai is the capital, argued that the media was blowing the issue out of proportion, and requested that residents 鈥渦nderstand the situation and cooperate鈥 until expected fall rains.聽
For a large percentage of the city, however, regular access existed only on paper. In Kannagi Nagar, where Eswari lives聽鈥 a neighborhood built to resettle slum residents聽鈥 the tankers were both inaccessible and unaffordable, and scarcity began almost a year ago.聽
In a report submitted to the state high court, the government reasoned that the lakes began drying up after a failed monsoon in 2017, following which the city鈥檚 water supply had been reduced by more than a third. But the court criticized the state鈥檚 lack of management and passivity, asking questions about attempts to source other water as the lakes ran dry, to preserve excess rainwater, or to reclaim bodies of water from encroachment.
Chennai, the commercial hub of south India, has been expanding for decades. By 1975, it had already quadrupled in size, and there are plans to expand it sevenfold, making it the country鈥檚 second-largest metro area. A large part of the development has been at the cost of聽鈥 and literally over聽鈥 water bodies, whose number and size have shrunk rapidly.
The flat, coastal city lies in the rain shadow of the Eastern Ghats mountain range, and needs to be designed with that geography in mind, as well as the erratic nature of the northeast monsoon it relies on, emphasizes Nityanand Jayaraman, a Chennai-based environmental activist and journalist. The same reservoirs that had overflowed in 2015 and caused devastating floods in the city were now dry.
鈥淭he solution to both is preserving water bodies, and to build the infrastructure to help the water seep in, soak, stay, and flow,鈥 he says. 鈥淚f you can鈥檛 prescribe these four behaviors of water, you will get into trouble.鈥 Open spaces, which are also important for groundwater recharge, he adds, have been replaced with construction.
Neighbors step up
This month, monsoon rains have begun to arrive, restoring groundwater supplies. The last water train arrived last week, and the neighboring state of Andhra Pradesh has begun releasing water through canals toward Chennai. But some residents fear scarcity will return unless long-term solutions are adopted. 鈥淭here is a big worry. We have reduced water usage and started saving rainwater,鈥 says resident Lamuel Enoch, who says he has not had tap water for four months.
For Sunil Jayaram and his neighbors in Chitlapakkam neighborhood, the 2015 flood was a wake-up call to Chennai鈥檚 water management problems. The following year, their bore wells ran dry, with no groundwater even 400 feet down. The nearby lake 鈥渨as allowed to be encroached to a large extent and the rest of it was filled with garbage,鈥 Mr. Jayaram says.聽
Residents came together to form Chitlapakkam Rising, a group with about 2,500 volunteers, who began a drive to restore the lake. They began to clean the lake themselves, and after three years, successfully campaigned for a government desilting project.
Mr. Jayaram notes that the progress has been minimal, but that the scarcity led to greater awareness and initiative. 鈥淩ainwater harvesting is definitely picking up. I see a lot of individual houses redoing it themselves,鈥 he says. Resident welfare associations have constructed dozens of pits along road corners to collect water, as well.聽
Throughout Chennai, residents have taken responsibilities on their shoulders. There鈥檚 Suryakumar, a resident of Triplicane, one of Chennai鈥檚 oldest neighborhoods, who wakes up at five every morning, heads to the pumping station a mile and a half away, and accompanies a public water tanker back to the narrow street where his home is. He directs traffic and helps residents fill their pots with water before getting ready for his day of work at a courier service. 鈥淚 have had to take this responsibility because the metro or the driver don鈥檛 care if there鈥檚 no water in my neighborhood tomorrow. But I do,鈥 he says.
Many, like Eswari, feel as if they have been left to the margins.
鈥淲e just want the government to provide at least one other alternate source of water,鈥 one of her neighbors, Ramu, says solemnly. 鈥淓ven if the water is salty or contaminated, we can use it for something. We can manage. It will be better than the many days when we have nothing.鈥
