6. 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.

 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
• Diversion Dyke made of SSM-Sewage
flowing into STP
(1 ft depth trench beneath has been made)
