Detroit · Free · No sign-up

Detroit is spending $184M on sewer connections.It won’t say where.

Free if a contract reaches your alley. $5,000 to 25,000 if it never does. No application, no list, nobody is told either way, so I reverse-engineered the City’s selection model from its own open data and scored every address in Detroit.

Three real addresses, three different answers

  1. 1A likelihood, not a maybeAlley cave-ins, block-group income, council district and distance to contracted work, the four criteria DWSD publishes, measured at your address and compared against the 138 alleys it actually chose. Validated at p < 0.0001.
  2. 2Then the call, scriptedThere is no list to look up, so the answer always ends in a phone call. Every number here comes with what to say, the three things to ask, and what to have written down before you hang up.
  3. 3And everything else that reaches youSix segments of pipe, who owns each, and every City program checked against this one address, plus the 45-day damage claim, which is a different pot of money and a deadline most people miss.

The money is not going where the basements flood.

Blue: every home that told the City it had water in the basement since 2023. Orange: the 138 alleys in the first round of contracts.

How I worked this out ↗

Nobody else can answer this

The City publishes the criteria but not the list, and the 30,000+ failed-connection data points behind it are in none of its open datasets, I checked all 782. Reconstructing it from what is public is the only way a household can see anything at all.
