Sewer overflow traced to severe blockage in main pipeline

Officials said sewage overflow occurred after the main sewer pipeline developed a severe blockage, causing backflow and sewage spilling onto roads in Chander Nayak Thanda and surrounding localities.

The issue drew several complaints on social media and to the HMWSSB Metro Customer Care. Local public representatives also raised the matter with officials.

Blankets, bedsheets and plastic found during desilting

A Madhapur circle team worked continuously for three days to clear the blockage. Using high-pressure jetting machines and telescopic hydraulic grabber equipment, workers removed silt and debris from the main sewer pipeline and restored the sewage flow.

During the desilting drive, officials recovered blankets, bedsheets, clothes, plastic items and other solid waste from manholes.

Officials said such waste accumulates inside sewer lines and blocks the flow of sewage, leading to frequent overflow complaints in several parts of the city.

Officials warn of action against dumping waste

Authorities said desilting drives often clear accumulated silt, but the problem returns when people continue to dump waste into manholes.

"Public awareness and cooperation are essential. Without that, even repeated drives cannot solve the problem permanently," officials said.

They warned that strict action would be taken against those dumping garbage and solid waste into manholes.

Food waste from commercial buildings adds to blockage

Officials also said hotels, offices, bakeries, food courts, commercial establishments and residential complexes often connect their sewer pipelines directly to the HMWSSB network.

In many cases, they do not install silt chambers, allowing food waste and other solid materials to enter sewer lines and manholes. This increases pressure on pipelines and causes sewer overflow.

The board urged such establishments to construct silt chambers so that solid waste gets trapped before entering the sewer network.

Officials appeal for public cooperation

Officials said responsible behaviour from citizens is essential to prevent sewer blockages.

Workers often remove large volumes of waste during desilting operations, including plastic covers, water bottles and other solid materials.

"If people cooperate and stop dumping waste into manholes, sewage will flow freely and overflow problems will reduce," officials said.

They appealed to citizens to avoid throwing garbage, plastic or construction debris into manholes.

"Manholes are not garbage bins. Keeping the city clean is everyone's responsibility," officials added.
