Utility Department WELCOME KEEPING WATER CLEAN & SAFE IT IS EVERYONE'S JOB TO PROTECT WATER FROM UNNECESSARY POLLUTION FUNDING:         Even though the Onalaska Utility is an agency of the City of Onalaska, it operates independently of the City's general fund and any tax dollars. The Utility's funding is derived from the rates it charges its customers for water and sewer service. Customers are billed for water and sewer service on a quarterly basis. Onalaska's water rates are established by the Public Service Commission of Wisconsin, which regulates public and private utilities throughout the state.
