BANGALORE: As part of its Environment Action Plan, the Bangalore Water Supply and Sewerage Board (BWSSB) is planning to reconstruct all the major sewer lines of the city by the end of 2015.
Some of the trunk sewer lines that are being replaced were laid more than 35 years ago.
The water board has prepared a detailed project report for replacing 110 kms of trunk sewers at the estimated cost of Rs 350 crore under its Plan C.
“Till now, we have been reconstructing the old and dilapidated stretches of trunk sewers in the city,” said PB Ramamurthy, the board’s chairman. “With the implementation of Plan C, we will replace all the trunk sewers in the city and that will help us prevent the sewage from flowing into storm water drains, which is the purpose of our zero sewage plan.”
The project reports need to be approved by the Cabinet.
Under plan A, the water and sewerage board has completed replacing 30 kms of trunk sewers that cost Rs 46 crore.
It is in the process of awarding contracts for replacing another 80 kms of sewer lines for Rs 175 crore.
In Plan B, the board will replace the sewer lines that were laid under the storm water drains.
At present, nearly 900 million litres per day (MLD) of sewage is discharged by the city everyday and the water board is able to treat only about 450 MLD as the remaining sewage is flowing into the storm water drains.
‘’Once we stop the sewage from entering or overflowing into the strom water drains, we will start our project to collect the rain water that falls in the city and pump it for potable purposes after treating it,’’ Ramamurthy said.
