Common questions

How do I file a "Water in Basement Complaint" request with Chicago 311?
Three ways, all of which create the same public record: online at 311.chicago.gov, by calling 311 from inside the city (or 312-744-5000 from outside it), or through the CHI311 mobile app. Give the exact address or nearest intersection — requests without a usable location are the ones that stall. Requests of this type are routed to DWM - Department of Water Management.
How many "Water in Basement Complaint" requests does Chicago get?
66,751 have been filed in total, excluding duplicates the city flagged. 764 came in over the last 30 days, down 50% versus the previous 30 days.
How long does a "Water in Basement Complaint" request take to close?
The city does not publish a target response time for this request type, and this page does not estimate one. What the data does show: 93% of all "Water in Basement Complaint" requests are marked Completed and 0% are still Open. The rest were canceled — usually duplicates or requests that turned out to be someone else's jurisdiction.
Is my 311 request public?
Yes. Every service request becomes a public record in the city's open data portal, including the type, status, the street address (block level), the ward, and the dates it was opened and closed. That is exactly what this page is built from. Your name and phone number are not published.
