• Collected water cess arrears and amount will be invested in the projects taken by BWSSB for rejuvenation of lakes.

• Insisted to discharge sewage water into lake after treatment.

• A proposal for pumping of treated water to Bangalore University campus.

• Initiated action on diversion of waste water from open drain to manhole, which ultimately joins to nearest treatment system, then to lakes.

Construction of silt trap in stages will reduce the flow of sewage in the drain gradually.

Action not yet taken to utilise the full capacity of V.Valley STP(only 30% being used).

Entire BBMP area has to be covered by the BWSSB and any direct discharge from the erstwhile CMC area into any lakes has to be prevented.

BWSSB has to enter into an agreement with horticulture Department, Forest Department, BDA for programmes such as stone pitching, beautification by gardening, making walkway etc.

Sewage in its septic condition to the tune of about 12 to 15 MLD (Peenya and other area) is bypassed from Madavara lake and the same further joins T.G.Halli Catchment. The same can be uploaded into Nagasandra STP which is operating at 30% its capacity.

The sewage treatment/diversion at V.Valley region is below par.

Lakes/Tank Water Quality improvement interventions

Taken up issue of arresting sewage flow into lakes with BWSSB –Inflow to STPs reached 63% as on 28-2-2013 of installed capacity (721 MLD)

Improved sewage inflow into K.R.Puram STP by diverting sewage from the near by open drain thereby augmenting flow from 6 MLD to 10 MLD
