The general guide on RTI for water supply / contamination covers the full template, decision steps, case law and FAQs. This page focuses on the Mumbai-specific bits: which municipal department to file at, what fee mode Brihanmumbai Municipal Corporation (BMC) accepts, the local portal (if any), and where to escalate within Maharashtra.

1. Identify the office. Brihanmumbai Municipal Corporation (BMC) (Municipal Water Department / Jal Board) typically sits at Brihanmumbai Municipal Corporation (BMC) headquarters or the relevant zonal office.
2. Pay the fee: Rs. 10 IPO/cash; check the Maharashtra hub for any state-specific fee.
3. File: online via https://portal.mcgm.gov.in/ OR by Speed Post to Brihanmumbai Municipal Corporation (BMC) (with acknowledgment).
4. Track: 30-day clock starts from receipt by the public authority.

1. Day 31: file First Appeal under §19(1) to the FAA (typically the Municipal Commissioner of Brihanmumbai Municipal Corporation (BMC)).
2. Day 75-76: file Second Appeal to the Maharashtra State Information Commission.
3. Parallel pressure: Use the Brihanmumbai Municipal Corporation (BMC) grievance portal (if available) and CPGRAMS (pgportal.gov.in).
