Nemmeli desalination plant to be ready by 2023 – Chennai – India

Chennai MWSSB has begun work to lay pipelines to draw seawater and discharge brine from the upcoming third desalination plant at Nemmeli. The plant will have a capacity to treat 150 million litres of seawater a day (mld).

Over 50% of the construction of seawater intake sump, ultrafiltration, reverse osmosis, and dissolved air flotation, in the plant has been completed so far.

The CMWSSB has laid cofferdams (a structure that enables work to lay pipelines for the desalination plant).

Reservoirs full but Chennai still buys water – India

Heavy rains have kept Thervoy Kandigai reservoir brimming since Sunday. In fact, it’s been filled to capacity multiple times since it was commissioned last November. But not a drop from the waterbody — built at a cost of Rs 380 crore to augment Chennai’s drinking water supply — has been used.

That’s because the city’s other reservoirs (Chembarambakkam, Poondi, Red Hills and Cholavaram) already have enough water, says a senior official from the CMWSSB.

But water is still being bought from desalination plants to meet the city’s needs. On Tuesday too, 68 MLD was purchased from the Nemmeli desalination plant, and 45 MLD from the Minjur desalination plant, triggering questions from experts.

Chennai receives 1,000 million litres of water – India

For the first time since the formation of Chennai Metro Water Board in 1978, the water supply has touched 1,000 MLD on Friday.

Copious inflow into the reservoirs due to good rainfall and the release of Krishna water from Andhra Pradesh are the major reasons for this, say officials.

On Friday, the five reservoirs (Chembarambakkam, Poondi, Red Hills, Cholavaram, and Thervoy Kandigai) together had a water storage level of 9.5 TMC.

Seawater desalination unit brings relief to drought-prone Tamil Nadu village – India

The Ministry of Science and Technology on Saturday informed that seawater desalination through “solar thermal forward osmosis” has brought relief to a drought-prone village in Tamil Nadu.

Narippaiyur, a village in Ramanathapuram District, a drought-prone area situated in the South-East corner of Tamil Nadu will benefit from 20,000 litres per day of freshwater produced from the seawater – thanks to the solar thermal Forward Osmosis (FO) sea-water desalination system installed in the place.

As per the official release by the ministry, the customized demand-driven convergent water solution through FO will supply two litres of good quality drinking water per person per day for 10,000 people in the village, successfully overcoming a major drinking water shortage in the village.

Why Chennai’s water crisis should worry you – India

Having gone without a single drop of rain for about 200 days at a stretch, Chennai finally got some rain on Thursday. But this is way too little, and way too late for a city experiencing its worst water crisis in 30 years, and headed to becoming a Zero City.

School bags have grown bigger as children carry more water bottles, and Tamil Nadu’s apple of the eye – the famed Information Technology Corridor – has been pushed to the brink.

Companies have started asking employees to work from home and bring their own water. Water is rationed in residential apartments and malls are asking their water-intensive outlets to either take a break or use the blue gold frugally.
