​Toilet Rebates and Other Incentives

​You can save hundreds of gallons each year by replacing leaking or outdated toilets.  Many Wisconsin water utilities offer rebates or other incentives to customers who install WaterSense-labeled toilets, faucets, showerheads, and other products.  Some utilities also offer low-cost or free rain barrels for their customers.  Contact your local water utility and ask whether they have a water conservation program and whether you may be eligible to receive assistance.

Additional water saving tips and information:

Each Wisconsin water utility is required to implement basic water conservation and efficiency measures, including metering all water sales, conducting routine meter testing, monitoring losses and leaks in the distribution system, and collecting and reporting water audit information to the PSC. These requirements can be found in Wis. Admin. Code ch.185.

Water utilities often provide additional leadership and funding for community conservation efforts, which can include demand-side measures such as water fixture rebates, incentive programs, education and outreach, customer water audits, restrictions on lawn watering, and water rates that encourage water efficient behavior. Water conservation programs also include supply side measures such as non-revenue water control. Successful water conservation programs combine both demand-side and supply-side efforts and are integrated into utilities and planning for future supply sources. Because each utility is unique, there is no single approach to water conservation that is appropriate for all.

Residential Customers

A utility may ask a new residential customer to post a deposit if they owe an undisputed bill for any utility service incurred in Wisconsin within the last six years.

A utility may ask a current residential customer to post a deposit if:

  • Customer’s service was shut off during the last 12 months.
  • Customer falsified a service application.

Residential deposits are returned with interest after 12 consecutive months of prompt payment.

The utility may accept, in lieu of a residential cash deposit, a contract signed by a guarantor satisfactory to the utility. The contract guarantees a specified sum not exceeding the amount of the cash deposit or guarantees payment of all future bills.

Commercial Customers

A utility may ask a current commercial customer to post a deposit if:

  • Customer has not made prompt payment of all utility bills in the last 24 months.
  • Customer’s service was shut off during the last 12 months.

Does the PSC regulate sewer utilities?

While all Wisconsin water utilities are regulated, sewer utility regulation is a voluntary decision on the part of the municipality. Investor-owned sewer utilities would be regulated, but none currently exist. Municipal sewerage systems (sanitary as well as storm water) do not fall within the definition of “public utility” under Wisconsin Statute § 196.01(5) and therefore do not require PSC approval when setting rates and rules. 

Although the PSC does not regulate any sewer systems, it has limited authority over municipal sanitary sewer issues. Pursuant to Wis. Stat. § 66.0821(5)(a), any user of a sewer system may file a complaint with the Commission concerning the rates, rules, or practices of the municipality. Upon receiving a complaint, the PSC reviews the re​asonableness of the municipalitys rates, rules, and practices. As these operations are not public utilities fully regulated by the PSC, it is the responsibility of the complainant to de​velop the basis for complaint. Generally, individual, informal complaints are reviewed by PSC staff, whereas more formal or legal questions are set for hearing, with parties developing a record in support of their individual positions. The Commission decides the issues based on the merits of the hearing record.​
