Plumbing Retrofit Program

​​​​​​​​​​​​​Since the 1990s, the City has offered a Plumbing Retrofit program to City customers. The program helps City customers who are single-family homeowners on limited or fixed incomes by assessing water use at their homes and improving their water use efficiency. Since the program is designed for customers in need, referrals originate from the Human Services and Neighborhood Service Departments.

How the Program Works: A referred customer will be contacted by postcard or letter inviting them to participate in the program. The card has instructions for setting an appointment with the City contractor. Once at the house, the City contractor will assess water use at the customer's home. The contractor will make recommendations and provide information about water use, assess the home for leaks and the need for plumber service, and, if needed, replace older, inefficient fixtures, such as toilets and faucets, with newer, more efficient models. 

Qualifying Households must:​
  • Have a house built prior to 1994
  • Have toilets that flush more than 1.6 gallons per flush
  • Arrange for any debris (including the old toilet) to be properly disposed of in bulk trash
  • Not have participated in the program in previous years
