BANGALORE: To meet the increasing water demands of the city, the Expenditure Reforms Committee (ERC) has recommended the Bangalore Water Supply and Sewerage Board (BWSSB) to supply tertiary treated water in dual pipeline to erstwhile seven city municipal council, one town municipal council and other new layouts being developed by Bangalore Development Authority (BDA). With experts cautioning the water board about the possible water famine hitting the city by 2020, BWSSB had proposed an action plan to come up with solutions. As per the resolution, BWSSB is set to supply tertiary treated water in dual pipes to BDA layouts which are in initial stages. “Based on the need for the tertiary treated water, BDA should deposit certain amount with BWSSB for laying pipelines,” said S M Basavaraju, chief engineer, Waste Water Treatment. Presently, Bangalore receives 900 MLD water from Cauvery river in four stages, and an extra 500 MLD water will be supplied through the Cauvery water project which is expected to be commissioned by September. The supply of treated water is expected to reduce the consumption of fresh water. BDA Chief Engineer Chikkarayappa said, “We are supportive of such projects. Many layouts are still in the planning stage. We will implement the dual pipeline project in such areas. ” Former Irrigation Secretary Captain Raja Rao said, “There is a psychological barrier in consumers to use treated water. BWSSB should create awareness about tertiary treated water. ” “Out of the total 900 MLD, about 80 per cent of the water is generated as sewerage. We have 14 sewerage treatment plants which has a capacity to treat about 700 MLD,” said S M Basavaraju, Chief Engineer, Waste Water Treatment and Corporate Planning. “Treated water is supplied at lesser price as compared to fresh water. People must become aware of the advantages of the treated water and must be encouraged to use the water,” said Vishwanath S of ‘The Water Channel.’
