DIPPING BELOW ZERO: CHENNAI WATER CRISIS
Chennai’s primary sources of water – the four major reservoirs do not hold even one percent of their capacity (in other words dipping below zero level), the worst water crisis for the city in 30 years.Usual water sources, Red Hills, Sholavaram and Chemabarambakkam lakes have fully dried up. The four major reservoirs water levels have dipped below zero. Out of more than 6,000 lakes and ponds on the city outskirts only 3,896 now remain while, city’s own 150 water bodies have disappeared.
According to a report by the BBC, Chennai’s metro system has stopped using air conditioning at its stations. Public toilets in places such as malls have also reportedly stopped functioning.
THE GOVERNMENT’S RESPONSE
The state government announced a 220-km train that would run from Jolarpettai to Chennai carrying water every day. The 50-wagon train will make four trips daily to supply 10 mld of water and cost the government Rs 65 crore per day.
In addition, Kerela has to provide 20 lakh litres of water per day and the Cauvery Water Management
Authority has asked Karnataka to release water to Tamil Nadu. Reports also state that authorities have decided to approach Andhra Pradesh for seeking its share of water from the Krishna River.
The government has also reportedly issued an order to take up traditional water body restoration scheme to improve the groundwater table. It has allotted Rs 212 crore for digging deep borewells, according to reports.
According to a recent NITI Aayog report, 21 Indian cities will run out of groundwater by 2020 if usage continues at the current rate. Learning their lessons from the Chennai crisis, other metropolitan cities should wake up now.
SHORT-SIGHTED MEASURE IN PLACE OF LONG-TERM STRATEGIES
The stop-gap arrangements will soon be forgotten, when things temporarily go back to normal. Instead
government needs to find systemized solutions and developing deeply ingrain practices in the system to
prevent future crisis. For instance, after the alarming Chennai floods, no consistent actions have been deployed to clear wetlands or regain fast disappearing water bodies In 2000, rainwater harvesting (RWH) policy was initiated which mandated that building approval for new dwellings were not to be granted unless the building plan included a RWH component. The order also mandated that
all existing buildings in Tamil Nadu install RWH structures. Sixteen years later, an audit by the non-governmental organization Rain Centre has shown that most government buildings in Chennai do not have a functioning RWH structure.
The time has come, that all state governments should now monitor and regulate groundwater. Water supply should be measured and priced progressively, similar to the electricity tariff, where the quantity of use determines the price.
