The Nemmeli Sea Water Reverse Osmosis desalination plant located on the East Coast road, South of Chennai, was inaugurated by Tamil Nadu Chief Minister J.Jayalalithaa , paving the way for the city to receive additional water.
The water from Nemmeli plant will offset the shortage due to loss of water from Veeranam tank. At the inaugural function, Municipal Administration and Water Supply secretary K. Phanindra Reddy said that a plot of 40.5 acres was allotted for the plant. Of this, only 20 acres were required as fewer treatment units were built as the Nemmeli plant uses a compact and faster treatment process when compared to the conventional filtration system in Minjur.
MECON in association with ADECO Technologies provided the process technology. The state-of-art technology comprises indigenously designed marine intake system and pre-treatment system having up-flow filters, disc-filters and ultra-filters followed by reverse osmosis membrane system and post treatment system for re-carbonation and re-mineralisation of RO water.
The detailed project report (DPR) and the complete basic design & detail engineering for the plant was prepared and submitted by MECON in January, 2008 to Govt. of Tamil Nadu. Subsequently, Govt of Tamil Nadu sought for the clearance of the project and assistance of grant from Govt. of India. The Cabinet Committee on Economic Affairs gave their clearance for construction of Nemmeli desalination plant on 03.01.09 with 100% grant from the Centre.
