Bangalore Water Supply & Sewerage Board [Bwssb] — Overflowing of drainage and sanitary water in our locality

Dear Sir,
I would like to draw to your kind attention the serious and severe sanitary conditions of our locality. The drains are completely blocked from the past 3 years and there is no provision for the dirty water to flow out. The stagnate water is being filled in the septic tanks and the sewage water from the septic tanks started overflowing on the road and it is now entering our house corridor.
It is hard to walk or ride through since the dirty sewage water is entering our house corridor. The stagnant dirty and septic water has become the breeding ground for the mosquitoes and other germs which is causing health issues. It may lead to the outbreak of diseases. There is foul smell all around coming out from the rubbish and dirty drains.
We have been approaching the local Panchayat elected members from the past 3 years but no action has been taken till date from any officials. The present elected members are blaming the earlier elected members stating that, they have not constructed the drains properly. Also, they are saying that, they are not getting funds sanctioned from Panchayat office to rectify the drainage issues.
Please note that, the dirty water from the 2 huge septic tank of the opposite building dug in the middle of the road started continuously overflowing towards our house from one week and it is causing very serious health issues.
Expecting an immediate action. Enclosing herewith the photographs for your necessary action.
Regards
Naveena Denzil
