Bangalore Water Supply & Sewerage Board [Bwssb] — chamber block affecting sewage lines

Address: 560068

Chamber Block on 35th Main BTM L/O Dollar Colony is affecting sanitary line at no.23 & reverse flow of sewage water has broken through sanitary lines & causing inconvenience + HEALTH hazard.
I have personally complained at BWSSB office, Water Tank BTM 2nd Stage. A chamber cleaning Truck did come over. They said unless the main line on 3rd cross is cleared they cannot open our 35th Main chamber. They tried to clear the line on 3rd cross for over an hour. But the sewage would not budge.Last 4 days they have shifted their operations to near HSR L/O stating unless sewage moves from there the line on 3rd cross BTM 1st Stage Dollar Colony will not clear & only then 35th Main Dollar Colony can be attended to. We started precautionary civil works from Monday 23.4.18 to avoid last year's catastrophic mess & discovered that the chamber line was blocked with hardened sludge & Reverse flow of sewage water had already breached the sanitary line in our home & creating its line of least resistance & flowing. KINDLY CONSIDER AS PRIORITY & ACT before any serious damage is done. We have Dialysis, Diabetes & Stroke patients around 80yrs staying at no.23, 35th Main Dollar Colony. Please lend a helping hand .
