In four years, the city’s thirst will be successfully quenched as the Chennai Metro Water has invited international bidders to build a 400-MLD capacity seawater reverse osmosis desalination plant at Perur along the East Coast Road in Kancheepuram district.
Chennai to get fourth desalination plant, city reservoirs have enough water to last till summer – India
CHENNAI: The city’s thirst for water could be quenched in the next four years as Chennai Metro Water has started looking for international bidders to build the 400 MLD (million litres a day) capacity sea water reverse osmosis desalination plant at Perur along the East Coast Road in Thiruporur block of Kancheepuram district.
One year ago, Chennai suffered a historic drought. For nearly 200 days, the metropolis of 7 million people facing the Bay of Bengal in eastern India went without a drop of rain, pushing it to breaking point.
The Indian Institute of Technology Madras, or IIT Madras, has developed a solar ‘parabolic trough collector’ (PTC) system for concentrating solar energy for industrial applications like desalination, space heating and space cooling.
The Tamil Nadu Water and Drainage Board’s (TWAD) proposal to set up a 60 MLD Sea Water Reverse Osmosis (SWRO) plant at Kuthiraimozhi village in Ramanathapuram has been recommended for CRZ clearance by the Expert Appraisal Committee (EAC) of the Environment Ministry after a modified proposal was submitted.
Chennai Metrowater is drawing additional water from Chembarambakkam reservoir to maintain piped water supply in south Chennai to offset the gap in distribution following the shutdown of the desalination plant in Nemmeli.
The plant has a capacity to supply 100 million litres a day to various parts of south Chennai. It has, however, resumed piped water supply with alternative sources from waterbodies in Chembarambakkam and Veeranam.
Piped water supply to several areas in south Chennai may be affected for 15 days, from March 17, as Chennai Metrowater plans to take up work at the Nemmeli desalination plant, that has a capacity to treat 100 million litres of seawater a day.
The water agency will fix the travelling band screen, a self-cleaning screen in the seawater intake structure, at the desalination plant. The work will be taken up between 6 a.m. on March 17 and 6 a.m. on April 1.
Due to the work, piped water supply to areas 9, 13, 14 and 15 will be affected. The localities include Thiruvanmiyur, Kottivakkam, Perungudi, Adyar, Velachery, Besant Nagar, Mandaveli, Sholinganallur and Neelankarai.
CHENNAI: On Tuesday, CE reported that due to the lack of water supply in the tenements at Perumbakkam Resettlement Colony, a group of people including 50 women from the Colony stood outside the Tamil Nadu Slum Clearance Board (TNSCB), staging a protest, demanding basic needs including water. Soon, in response to the call of the residents, the TNSCB officials resumed water supply and told CE that they will ensure no further problem arises.
In line with the perennial water woes at the Resettlement Colony, the Slum Board officials have decided to soon increase the quantum of water being supplied to the tenements. In four months’ time, by when the construction of 14 more blocks will get over, the Slum Board officials said they will request the Metro Water Board to provide more water according to the needs.
