A building awaiting a completion certificate from the Kolkata Municipal Corporation (KMC) will get one only if its owner or developer has deposited all construction and demolition waste to a processing plant run by the civic body and obtained a certificate from the plant authorities.

The building’s owner or developer has to submit the certificate from the plant to get the completion certificate (CC) from the KMC. Linking the completion certificate to depositing construction and demolition waste in the plant will force building and plot owners to send the waste to the plant, KMC sources said.

The completion certificate is a proof that the building has come up in compliance with the KMC rules.

A plant in New Town, which can process 500 tonnes of construction and demolition waste every day, is receiving only about 90 tonnes each day, a KMC official said.

KMC sources said the waste is often used to fill water bodies or raise the height of plots. Improper disposal of construction and demolition waste can also increase air pollution.

On Sunday, Metro spotted pieces of bricks and concrete chunks dumped along the banks of a water body in Jadavpur. A resident said the size of the pond had shrunk over the years because of continuous dumping of concrete and other solid waste.

“No Completion Certificate will be issued unless the applicant furnishes the certificate issued by the plant operator,” an order by the municipal commissioner issued last month reads. The order also says construction will not be allowed unless the owner or the developer submits a certificate from the plant that the waste generated till the completion up to plinth level was deposited in the plant.

A KMC official said a fee will be collected from the owner for the processing of the waste when the KMC approves a building plan.

The owner can send the waste to the plant or ask the KMC to collect the waste. “We have about 50 vehicles to collect the waste. Those generating construction and demolition waste outside the KMC area can also send the waste to the plant,” the KMC official said.

The plant is supposed to make paver blocks from the waste generated in the real estate sector.

“Plot-owners will be held responsible and will have to pay a huge fine if it is found that the waste is dumped in an open place or a water body. They should check with the developer if the waste is being sent to the plant,” said a KMC official.

According to Construction and Demolition Waste Management Rules, 2016, someone found dumping waste in water bodies or sewer lines can be fined ₹2 lakh. Someone dumping waste on a vacant plot can be fined ₹20,000.

The KMC will also ask the PWD, KMDA and the railways to send their waste to the plant.
