Water supply to Chennai has been slashed by 50% as Tamil Nadu is undergoing its worst drought in 140 years.
Chennai receives most of its water from 4 water bodies Poondi Lake (3,231 Mcft), Sholavaram Lake (881 Mcft), Red Hills Lake (3,300 Mcft) and Chembarambakkam Lake (3,645 Mcft). All of the lakes are running dry. The veeranam lake which receives water from Cauvery river tributary has also dried up.
Piped water supply is limited to once in 3 days in many parts of the city to compensate with the supply shortage, authorities said 300 water tankers were being pressed into service to supply water to various parts of the city.
Water is being sourced from various other sources like desalination plants & neighboring districts to keep up with the city’s demand of 1,100 million liters a day.
“Water is also coming in from stone quarries in Kancheeputam and Thiruvallur, besides two desalination plants in the city,” according to NDTV
In 2015 Chennai, faced devastating floods resulting in overflowing lakes and in 2016 the failure of NE monsoon led to the current drought.
Environmental activists blamed the lack of proper regulations, exploitation of groundwater and unbridled urbanization for the current crisis.
