The Brihanmumbai Municipal Corporation (BMC) will start experimentation to improve the quality of water in creeks and the sea. To this end, it has decided to appoint a consultant to clean out stormwater drains (SWD), commonly referred to as nullahs, before their contents enter the sea. “The consultant will examine SWDs and create solutions to maintain the water quality around their outfalls,” said a BMC official.

“We have invited tenders to appoint a consultant to study the issue and suggest a solution,” said Ashok Mengade, chief engineer, Mumbai Sewage Disposal Project. “This comprehensive study, which will tackle with water pollution issues, will start after the monsoon,” he added. Recently, the BMC invited tenders for in-situ treatment of water in 26 nullahs, which will cost Rs 83 crore approximately. “The study is not a part of this project and it will be conducted in 227 places in Mumbai,” said the official.
