Pallavaram Municipality — Sewage block complaint CNN20230421ENG17/WARD/41/

Regd. my above complaint lodged on 21/4/2023, so far not resolved. Today a sewage lorry came with supervisor and some men only to put suction and empty septic tank of Door No.42 private property .Drainage is fully blocked in all the manholes of our street, I dont understand why one individual private property is given preference.
when asked to check problem in my house No.17 RBI COLONY, Chromepet they said they will check main line blockage first and then come and left. Drainage water is overflowing inside my house and standing stagnant in the entire street line. This problem is not new and we suffer frequently as there is no pumping station of regular check by UGD. I request immdt.solution permanantly for this drainage problem and oblige.
Thankyou
