Delhi Jal Board — Blocked Sewers

Dear Sir
I am a resident of 905, Dr. Mukherjee Nagar, Delhi 110009. My problem is the constant sewer blockage in our area. Earlier it was during monsoon that sewer water used to enter our homes and now in month of November, sewers of our lane are blocked. As a result dirty sewer water is entering our home. Recently all members of my family have recovered from CORONA . I don't want another threat due to sewage water entering our homes. We called a private sewer cleaner to clean, he said the entire lane is blocked. We have lodged a complaint to govt agency but no action has been taken . It's a constant problem . Out of Rs. 100 that we pay for water bill, almost 40percent is charged for sewage maintenance. We in Mukherjee Nagar hardly receive any services. At times even the drinking water we get in taps is adulterated with sewage water . Please help
