Residents of Kannagi Nagar and Ezhil Nagar complain of erratic water supply – Chennai – India

For three months now, water supply to the Kannagi Nagar and Ezhil Nagar tenements has been erratic and of poor quality, residents have complained.

Water stored in underground sumps and supplied through hand pumps is the only water source for the nearly 23,700 tenements in Kannagi Nagar and about 8,000 tenements in Ezhil Nagar.

One year after the drought: Has Chennai learned from its water crisis? – India

One year ago, Chennai suffered a historic drought. For nearly 200 days, the metropolis of 7 million people facing the Bay of Bengal in eastern India went without a drop of rain, pushing it to breaking point.

Already strained by a burgeoning population, water supply eventually hit rock bottom, upending the economy and the lives of the city’s residents.

As families across Chennai struggled to find water to wash, cook and keep businesses afloat, the state of Tamil Nadu came under fire for failing to prepare for and deal with the crippling shortage.

Desalination plant near Gulf of Mannar Marine National Park to get CRZ clearance – India

The Tamil Nadu Water and Drainage Board’s (TWAD) proposal to set up a 60 MLD Sea Water Reverse Osmosis (SWRO) plant at Kuthiraimozhi village in Ramanathapuram has been recommended for CRZ clearance by the Expert Appraisal Committee (EAC) of the Environment Ministry after a modified proposal was submitted.

The proposal was earlier not cleared owing to the location being within the eco-senstive zone of the Gulf of Mannar Marine National Park, to be precise, only 25 metres from its boundary.

The TWAD filed a modified proposal to the EAC for clearance submitting that the intake and brine disposal point has been shifted away the eco-sensitive area.
