Water service application forms can be downloaded and printed or obtained from the Water Utility Main Office at 119 E Olin Ave. A plumber signature is required on all water service applications. For new or replacement services, the property owner or authorized agent must also sign the application. If you have questions regarding water service applications, call (608) 266-4646.

Please make sure all applications and fees are submitted before beginning work.  Failure to do so may result in your customer being denied water service.

  • Connect to an existing water service (requires the signature of a master plumber),

  • Install a new water service (requires the signature of a master plumber and the property owner), or

  • Replace a water service (requires the signature of a master plumber and the property owner).
