Quick Reply: A blocked or collapsed drain is a municipal service failure — complain first to the ward office or the municipal helpline, and register it on the Swachhata app so it gets a ticket number and a clock. If it stays blocked, file an RTI to the municipal corporation for the desilting record: the contract, the last date the drain was cleaned, and who certified it. Monsoon flooding cases are won on exactly that file.
Owner: the urban local body — corporation, council or board — for the drain network in its limits
Complaint routes: ward office, municipal helpline, Swachhata app, CPGRAMS for central-scheme works
RTI fee: ₹10, to the CPIO of the urban local body
Statutory basis: the state municipal Act makes drains, sewerage and storm-water a municipal function
Drainage is the least glamorous service a municipality runs and the one most quickly tested by rain. One blocked storm-water drain can flood a lane, and one collapsed sewer can contaminate a water line. The failure is rarely mysterious — it is a cleaning schedule not kept, a desilting contract not supervised, or a repair estimated and never taken up. All three leave a paper trail, and none of it is volunteered.
Keep the ticket number. It is the difference between a request and a case.
The corporation is a public authority. The desilting and maintenance of drains is contracted, supervised and recorded — three documents that decide whether the blockage was negligence or misfortune:
1. The date on which the drain at _____ (location) was last desilted or cleaned, and the name of the contractor who did the work. 2. A copy of the desilting contract for this ward for the current year, including the frequency of cleaning stipulated in it. 3. The supervision report or measurement book entry for that work, and the name and designation of the engineer who passed it. 4. The number of complaints received for this drain in the last 24 months, and the resolution date of each. 5. The status of any repair estimate prepared for this drain, its amount, and the sanction stage. 6. The total desilting expenditure for this ward in the last three financial years.
The pattern this exposes is standard: work billed on schedule, measurement books signed, drain still blocked — a documented gap between the record and the street that no ward office wants in writing.
Real example. After Dr. Shrawan Kumar Pathak's lane flooded twice in one July, his complaint got the standard “cleaning in progress” reply. The RTI produced a measurement-book entry claiming the lane's drain had been desilted four days before the first flood — with rain-logged photographs of the date showing the drain untouched. The re-cleaning was supervised the following week, and the ward's desilting measurement books went to the standing committee's audit.
Complain first — RTI is for the record. But a repeated blockage is best killed by the desilting file, and that file only comes by RTI.
Then the Public Works Department owns it, and the RTI goes to the PWD division — the municipal route covers only drains vested in the urban local body.
A demonstrated service failure — cleaning billed but not done — supports a claim before the municipality and, for negligence, in civil court. The RTI record is the evidence.
It operates across urban local bodies on the national sanitation platform; where your corporation runs its own app or helpline, either ticket is valid — keep the number.
