Mumbai's Sewage Project Progress: Plants at 36% with Launch Soon
Mumbai is building new sewage treatment plants to clean wastewater.
These plants, costing a lot of money, are not finished yet.
They will clean sewage, turning it into water that can be used again for things like construction.
This helps the environment by reducing pollution and could also help businesses by giving them an alternative water source.
The project is expected to be completed over the next few years.
Mumbai's seven sewage treatment plant (STP) project is at 36% completion, with one year until phased commissioning.
The Rs 30,000 crore project, launched in 2022, aims to treat and recycle up to 2,464 MLD of wastewater.
STPs are being built at Worli, Dharavi, Bandra, Versova, Ghatkopar, Bhandup, and Malad, with varied completion rates.
The project will reduce untreated sewage released into Mumbai's water bodies, addressing past violations.
All plants will produce 100% reusable treated water, with 50% for non-potable uses and 50% released into water bodies.
