Bangalore to recycle used water for drinking purposes Khaleej Times Online -

Khaleej Times Online - Bangalore to recycle used water for drinking purposes: "The growing demand for water has forced the authorities in Bangalore to take up a project to promote use of recycled water for drinking purposes.

The demand for drinking water has reached 1.2 billion litres per day in Bangalore against the availability of 930 million litres per day. The Bangalore Water Supply and Sewerage Board (BWSSB) has decided to implement a Rs4.72 billion project to recycle water for drinking purposes under the Jawaharlal Nehru National Urban Renewal Mission (JNNURM).

According to a statement from BWSSB, the project has been sanctioned by JNNURM’s Screening Committee, which met in New Delhi last week. Under the project, BWSSB will collect used water in Visvesvaraya valley on the outskirts of the city. “The used water will undergo tertiary treatment, ultra filtration and membrane process. This will help the authorities to supply an additional 135 million litres per day once the project is completed by 2010”, the statement said.

Presently, the drinking water supply to Bangalore is being met by River Cauvery, which flows at a distance of almost 120kms from Bangalore, and the Thippegondanahalli reservoir. But, the 810 million litres from Cauvery and 150 million litres from Thippegondanahalli reservoir are inadequate creating a shortfall of more than 250 million litres per day."
