If a pipe bursts in a city rowhome causing damages to neighbors' basements who is responsible?

Bursting Pipes in the City

The person who did the damage is, however, they would have a case against the city for not shutting it off quicker if he could find a lawyer that would take it.

In Wisconsin, you would be responsible for damages to other people's property if your negligence caused the broken pipe. Was it old and in need of replacement, but you failed to replace it? Did you cause a clog that caused it to break? If you installed the pipe, did you install it incorrectly? Just because the pipe broke doesn't mean that you were negligent and are responsible for damages. The owners of the other houses would have to prove that you did something wrong.
