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).

Third desalination plant will be ready in 2023, says K.N. Nehru – India

The ongoing project to construct the third desalination plant, with a capacity to treat 150 million litres of seawater a day, at Nemmeli will be completed by April 2023, Minister for Municipal Administration K.N. Nehru said on Saturday.

During an inspection, he instructed officials to expedite ongoing work at Nemmeli, and also initiate measures to start the construction of a 400 mld desalination plant at Perur.

Mr. Nehru noted that nearly 9 lakh residents would have better water supply once the ₹1,259.38 crore desalination plant is commissioned in 2023.

Pipe laying work begins at Nemmeli desalination plant – India

Earlier this week, Metrowater started laying a 49 km-pipeline to carry water from the under construction desalination plant in Nemmeli to various areas till Pallavaram.

Like many others, the pandemic has affected the progress of the project to build a third plant in Nemmeli.

The ₹1,259.38 crore project to build another desalination plant along East Coast Road may get delayed by a few months beyond its December 2021 deadline.

Work on a third desalination plant in Nemmeli to begin by October-end – Asia

Work on constructing a third desalination plant at Nemmeli, along East Coast Road, is set to begin by the month-end.

The new plant, with a capacity to treat 150 million litres of sea water a day (mld), will come up on a 10.5-acre space on the same premises as the earlier 100-mld plant.

Metrowater officials said materials had been sought for the work to commence. The new plant too will employ the reverse osmosis process. But it will have additional components in the pre-treatment process such as dissolved air flotation and ultra filtration, to keep out sea algae and other particles in seawater from hindering the production process.

Foundation stone for 3rd desal plant at Nemmeli laid, to be ready by 2021 – India

To mark the beginning of construction of the new 150 MLD desalination plant, Chief Minister Edappadi K Palaniswami laid the foundation stone at Nemmeli on Thursday. 

While the Rs 1,259 crore worth project is funded partly by German funding agency KfW, a part is covered under the Atal Mission for Rejuvenation and Urban Transformation (AMRUT) scheme.

The state government has taken Rs 700 crore on loan from KfW and the rest from the Central government.

Centre defers clearance for 400 MLD desalination plant in Nemmeli – India

The Environmental Assessment Committee (EAC) of the Ministry of Environment, Forest and Climate Change has deferred clearance for a proposal of the Chennai Metropolitan Water Supply and Sewerage Board(CMWSSB) to set up a 400 MLD desalination plant at Nemmeli. The EAC will review the project only after a team to be set up undertakes a site visit and presents a report. The committee, however, has given CRZ clearance for a 150 MLD plant, while imposing a ‘penalty’ requiring CMWSSB to “not only develop a robust shoreline erosion control and management mechanism of the area but also submit an undertaking that it shall bear the full cost of environmental damage due to erosion that might arise of the proposed 150 MLD desalination plant”. The penalty was imposed after noting that CMWSSB had failed to prevent shoreline erosion while setting up a 100 MLD earlier. According to the minutes of the meeting held on November 28, CMWSSB during the 165th meeting held in January had requested clearance for setting up a desalination plant of 400 MLD capacity at a distance of 600 metres from the site of the proposed 150 MLD plant. – Space for two plants – The EAC said there was “considerable space available” at Perur, the proposed site, to establish both the plants. However, it noted that there was already significant erosion of the shoreline due to the 100 MLD plant commissioned there. A clarification was sought as to why two plants had to be set up instead of a single 600 MLD plant. – CMWSSB informed the EAC that the plants were being funded by different agencies. – “The committee observed that this cannot be reason to justify setting up two separate plants,” according to the minutes. The EAC then said that it would consider only the 150 MLD proposal at present, while dropping the second proposal “for the time being.” – The EAC recommended the 150 MLD proposal for clearance subject to certain conditions, including CMWSSB bearing the full cost of any environmental damage that may arise.
