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).

Andhra Pradesh’s first desalination plant to come up in Prakasam with Rs 35 crore – India

A desalination plant with an outlay of Rs 35 crore will come up soon to address the drinking water needs of 14 fishermen villages in the Ongole assembly constituency of Prakasam district. This will be the first such plant in the state.

The authorities have already sent a detailed project report (DPR) to the government and are waiting for approval.

Chief Minister YS Jagan Mohan Reddy, during his recent visit to Ongole, had promised to sanction a comprehensive project with an estimate of around Rs 400 crore to supply drinking water to the city and other surrounding areas.

How Va Tech WABAG is taking advantage of desalination and waste water business opportunities – India

On the outskirts of Chennai, in the village of Nemmeli, the outline of a vast desalination project has been functioning smoothly since 2013.

At 100 million litres a day, it serves a critical need in supplying the water needs of a rain-starved region.

It’s an important poster boy for desalination technologies that are likely to become more prominent in the years to come.

The year our home in Madurai ran out of water – India

In the summer of 2013, we ran out of water in our home in Madurai. Like many others, we depend on the water that our borewell supplies, but after drilling past 500 feet, we hit a slushy bottom – our borewell’s way of telling us to look elsewhere.

An electrician familiar with the workings of our house for decades said the house had never run out of water, which made us inclined to believe this water outage was a passing problem and more to do with the working of the borewell.

My emails from this period reflect our concern with the functioning of the borewell and the muddiness of the column rather than with any fear of the aquifer drying up.

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.
