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.

Tax regime delays Chennai’s third desalination plant – India-Chennai

Floating of tender for Chennai’s third desalination plant has been delayed due to the Goods and Services Tax.

The tender for 150 MLD (million litres daily) desalination plant to be set up at Nemelli was scheduled to be floated on August 31. However, it was delayed due to GST, sources said.

The plant which is being funded by German agency KfW has been delayed over the price of components to be supplied for the project as it has to be reworked following the introduction of GST.

It is learnt that the tender is likely to be floated after September 15. Similarly, a 400 MLD desalination plant at Nemelli, which is financed by Japan International Cooperation Agency (JICA), is still being worked as Metrowater has to submit a revised detailed project report.

Currently, Metrowater relies on Minjur and Nemelli desalination plants to quench the thirst of Chennai. … (LINK)

Deploy more water tankers

Flays AIADMK for inaction on crisis

DMK working president M.K. Stalin on Sunday urged the State government to deploy more water tankers at cheaper rate to meet the drinking water requirements of Chennai.

In a statement here, he said there was no water in the lakes that supplied drinking water to Chennai and people had been forced to fetch water from quarries.

“Even though the desalination plants created during the DMK regime in Minjur and Nemmeli help overcome the crisis in South Chennai to certain extent, the AIADMK government has not done anything in the last six years to tide over the crisis,” he alleged. Mr. Stalin said even though the AIADMK government announced a desalination plant at a cost of Rs. 1371 crore in Nemmeli and another plant at Porur at a cost of Rs. 4,070 crore, both the projects remained only on paper.

Red alert: Worst water crisis see Chennai’s reservoir dry after 14 years (India)

Chennai is facing a water crisis similar to that of 2003-04, as the Red Hills reservoir, one of the city’s key water sources, has dried up for the first time in nearly 14 years. The reservoir previously ran dry in 1983 and then in 2003-2004; and in the first week of November 2015, had around 20 million cubic feet of water before rains came to the city’s rescue, said a Metro Water official. “Our only hope is the desalination plants — which provide 180 MLD of water — and groundwater sources,” the official added.
With several parts of the city dependent on water tankers and bo­rewells, Metro Water has alr­e­a­dy nearly halved its supply. Water managers are hoping to maintain the city’s supply at 470 MLD.

The impact of the drop in water supply can be seen on groundwater levels as more than two-thirds of households use borewells.

Stone quarries in Kancheepuram and Thiruvallur and the two desalination plants in the city are the primary sources of drinking water now. Chennai – India

Drinking water supply to Chennai slashed by 50% as Tamil Nadu braces for worst drought in 140 years.

Drinking water supply to Chennai has been slashed by 50% as Tamil Nadu stares at its worst drought in 140 years. Water supply officials told NDTV that the capital city, which requires 830 million litres of water per day, has been receiving only half of it for the past few days.

To make matters worse, the four main reservoirs around Chennai – Poondi, Red Hills, Cholavaram and Chembarambakkam – are all running dry, which means piped water for drinking is being supplied to certain areas only once in three days.

Authorities are now trying to pump 90 million litres a day to Chennai on the pipeline that draws from the Veeranam lake in Neyveli. Stone quarries in Kancheepuram and Thiruvallur and the two desalination plants in the city are the other primary sources of drinking water now. Authorities have also deployed an additional 300 water tankers in the city.

Chennai Turns Dry As Tamil Nadu Faces Worst Drought In 140 Years – India

Tamil Nadu is suffering the worst drought in 140 years. Chennai is getting drinking water from Neyveli and Thiruvallur
Chennai | Reported by J Sam Daniel Stalin, Edited by Anindita Sanyal | Updated: June 26, 2017 14:34 IST

Chennai: Chennai is facing an acute crisis of drinking water as all four lakes around the city have dried up, the local authorities have said. Tamil Nadu is witnessing the worst drought in 140 years. The city requires 830 million litres of water a day, but the supply has halved over the last few days, say water supply officials.

There is no daily supply of drinking water in Chennai as the four main reservoirs — Poondi, Red Hills, Cholavaram and Chembarambakkam are dry.

In many areas, piped water is being supplied only once in three days. The authorities have deployed 300 water tankers in the city.

The Veeranam lake in Neyveli, a town more than 200 km away, from where Chennai receives supply through a huge pipeline is dry too. The authorities, however, are tapping other resources in the area to pump 90 million litres a day to Chennai through the same pipeline.

“Water is also coming in from stone quarries in Kancheeputam and Thiruvallur, besides two desalination plants in the city,” a senior water supply official said.

The groundwater in Chennai and its surrounding areas is replenished…

How rain-rich Chennai depends on the sea for its water supply

At present, TN accounts for 24% of the total desalinated water capacity in India, second only to Gujarat. Experts meanwhile describe desalination as a “last option”.S Janakarajan, professor at Madras Institute of Development Studies, says that seawater desalination was conceived for rich, rain-starved countries like those in West Asia. “Chennai’s average annual rainfall is well over 1,200 mm. It should ideally be the last resort which, in this case, is not,” Janakarajan said. With scant supply , water distribution is charted out daily by the CMWSSB.”Our planning [daily distribution] hinges on how much water the desalination plants supply ,” Arun Roy , managing director of CMWSSB, said.

On average, the two plants churn out around 180 mld of the 470 mld CMWSSB now supplies, against Chennai’s demand of 1,300-1,400 mld.The plant in Minjur caters to industries and a few localities in north Chennai, while the Nemmeli plant caters to nearly 13-15 lakh residents in south Chennai, which is also house to the city’s IT hub.
