Bangalore Water Supply & Sewerage Board [Bwssb] — Sewage backflow into the building

Address: 471.3 rd stage,3 rd block,Basaveshwarnagar,Bengaluru, Bangalore, Karnataka

Dear Sir
tender sure project in siddaiah puranik marg, Basaveshwarnagar is going on for past 4-5 years.Work done is incomplete and poor.Connection to main sewage line from individual house is not done properly resulting in back flow of sewage.Manhole near Hotel Nisarga frequently gets blocked and once the BWSSB staffs clear the block by using pressure pump, sewage gets into neighboring building and individual line gets blocked.
Requesting you to direct the authorities concerned to solve the problem permanently.
