Bangalore: BWSSB plans water supply for 110 new villages

BANGALORE: The Bangalore Water Supply and Sewerage Board (BWSSB) is preparing a Detailed Project Report (DPR) to provide drinking water and sanitary facilities to the 110 villages that were recently added to the city. With this, BWSSB also faces the daunting challenge of managing its limited available drinking water resources.

Though the combined area of these villages is 224 sq kms, it is scattered across different parts of the city in different proportions. This entails BWSSB to study the topography of each of the villages and make a separate plan for each of them. Unless the government approves the DPR, the plans to generate funds to provide the aforesaid facilities to the villages cannot be executed.

The sewage flows out of the city only through Vrishabavathi Valley, Koramangala Valley, Challaghata Valley and Hebbal Valley. Therefore, underground drainage (UGD) flow from these areas has to be directed to the nearest valley. Some of the connecting tunnels, especially towards the northern and eastern parts of the city, are already flowing to their full capacity and are not in a position to hold extra load. It is also practically impossible to lay new UGD lines to connect these villages to the drainage valleys.

BWSSB is planning to supply water from the Cauvery to these areas in 2012 after the completion of Cauvery IV Stage, II Phase, as it will then get an additional supply to 500 million litres per day (MLD) of water. At present, BWSSB needs another 200 MLD of water to meet the needs of the core city. With the remaining 300 MLD, it is impossible to meet the needs of the newly-added areas. BWSSB is also supposed to show source of water in the DPR.

A BWSSB official said, “We have already started to prepare the DPR and it is a challenging task. It will take some time for the report to be completed.”
