Madras HC pulls up TN govt over water crisis, asks for report on measures taken – India

Even as the state of Tamil Nadu is in the throes of a severe water crisis, the Madras High Court has pulled up the state government on measures it has taken. The state government has been directed to file a report on how it has addressed the issue by June 17. 

According to a report in The Hindu, the court was hearing cases filed against the commercial exploitation of groundwater from the outskirts of the city. In particular, one public interest litigation (PIL) from a resident of Vellore district had alleged that sewage was being allowed to flow through into a water channel.

A division bench of Justice S Manikumar and Justice Subramonium Prasad also sought details of the number of sewage treatment plants (STPs) present.

Tamil Nadu to approach A.P. for Krishna water – Chennai

The Tamil Nadu government is likely to approach Andhra Pradesh for seeking its share of Krishna water as soon as the latter starts getting heavy inflows in its reservoirs after the southwest monsoon progresses.

The availability of Krishna water has become critical to Chennai, which is in the midst of an acute water shortage. Even though Chennai Metro Water Supply and Sewerage Board is making efforts to tap every conceivable source, this will, at best, sustain the water supply of around 500 million litres a day (MLD).

Without Krishna water, the supply cannot be restored to the normal level of 830 MLD – 850 MLD.

Chennai: Acute water shortage puts hotels in crisis control mode – Chennai

CHENNAI: Acute water shortage has affected the hospitality industry, with hotels welcoming guests with caution notice and restaurants replacing plates with plantain leaves. Being one of the largest water guzzling sectors, hotels and restaurants largely depend on private tankers for sourcing water.

While the hospitality industry has taken contingency measures to tackle the looming crisis, hotel associations are raising concern over a possible shutdown if tankers cut down the supply. South India Hotels and Restaurants Association (SIHRA) secretary T Natarajan said that hotels urge guests to conserve water.

“In the welcome letters, we appeal to our guests to be prudent over water usage in the light of prevailing water shortage. So far, private water tankers have been supplying water — at a huge cost,” he said.

Metrowater taps all resources to quench Chennai’s thirst – Chennai

Aware of the grim water situation facing the city, Metrowater has initiated about a dozen measures, including erection of new borewells with power pumps, setting up additional filling points and extending operation of tanker lorries. The most serious problem surrounds the level of water in the reservoirs at Poondi, Cholavaram, Red Hills and Chembarambakkam.

Cholavaram, the smallest with a total capacity of 1,081 million cubic feet, on Friday had a mere 9 million cubic feet of water. Officials had stopped the drawing from its dead storage level since a few days ago, said Metrowater executive director T Prabhushankar.

A visit by TOI showed cattle grazing on a large swathe of the lake bed.

Chennai: Metrowater starts to draw from farm wells – Chennai

Metrowater has started drawing 15 million litres a day from 300 wells on agricultural land it has leased in Tiruvallur, Tamarapakkam and Minjur to meet the city’s water needs.

Metrowater managers say the supply situation isn’t too bad with 180 million litres a day piped from Veeranam lake and an equal quantity from the two desalination plants too, but cause for worry is the depletion of the groundwater table in the city.

If needed, more water could be drawn from the wells. Water drawn from these wells is pumped into the Puzhal reservoir. After treatment, the water is piped to Anna Nagar, Kilpauk, Kolathur, Korattur, Ambattur and up to Nungambakkam lake area in the heart of the city, a senior officer said.

Veeranam lake turns a major water supplier for Chennai – Chennai – India

The Veeranam lake that was dug more than 1,000 years ago by the Chola kings in the then South Arcot district of Tamil Nadu has become a saviour for the city. Many residents are unaware that the lake meets more than 35% of city’s water requirement. Now, the lake is brimming with water due to the release from Mettur dam.

The released water reached the lake last Wednesday. This is the second time the lake is full to its maximum capacity in the last one year, said public works chief engineer P Jeyaraman.

A Metrowater engineer said the total capacity of the lake is 1,465 million cubic feet (mcft) of water. Currently, 6 mcft, or 180 million litres, is being drawn from the lake every day. This water reaches the city through pipes passing through Villupuram and Kancheepuram districts.

Chennai: Metrowater pins hopes on Veeranam, borewells.

With Chennai’s four water reservoirs running dry, Veeranam lake, 240km away, could be the oasis this summer.

The city’s water managers are pinning hopes on the lake, water from quarries in Sikkarayapuram, desalination plants in Nemmeli and Minjur, and giant borewells to tide over the crisis.

Chennai to get 500 million cubic feet of water from Mettur – Chennai – India

The State government has decided to provide the city with an extra supply of around 500 mcft of Cauvery water, a portion of which was released from the Mettur dam on Sunday night, and is expected to reach Veeranam tank in Cuddalore in 10-12 days.

With just less than 700 mcft of water left in all four reservoirs of the city, supply of Cauvery water comes at a crucial time as the city is slipping into a severe drought situation.

This extra supply of water will comfortably last till July while quarries, mines, agricultural fields and two desalination plants will act as additional water sources, said officials.

LTTD-based desalination plant to come up at Thoothukudi? – India

With thermal power plants being the largest industrial users of water and exceedingly contributing to water-stress, Chennai-based National Institute of Ocean Technology (NIOT) has come out with a novel concept of using coolant water discharge from power plants to produce fresh water.

Thoothukudi Thermal Power Station will be the first in the country to have an in-house 2 MLD (million litres per day) desalination plant based on Low Temperature Thermal Desalination (LTTD) technology.

This assumes significance as the Thoothukudi power plant is constantly accused of depleting the Tamirabarani water by drawing fresh water from the Srivaikuntam dam.
