Water Utility

The City of Oshkosh Department of Public Works must complete a database of all lead water service lines within the city by September 1, 2024.

It is easy to find out what material your water service line is made of:

  1. Click Self-Submit Your Service Line and fill out the brief form.
  2. Take photos* of your water service line and water meter. (*The total combined size of the photos must be less than 15MB. e.g., photo 1 + photo 2 + photo 3 + photo 4 = 15MB or less.)
  3. Upload the photos.
  4. Click Submit.

A Water Utility staff member will review the information and respond with what material your service line is made of and any next steps.
