Printable Overview and Application

The purpose of the Water Conservation Rebate Program is to encourage residents to reduce water consumption. Rebates will be distributed on a first-come, first-served basis until funds are depleted and will be credited to the Derby Utility customer’s account. The program is funded entirely by a $25,000 rebate allowance from the City of Wichita which is shared amongst its wholesale customers.

Rebates are available to all Derby Utility customers, including residential and commercial, owner-occupied, and rentals. Any qualifying device purchased between Jan. 1, 2023 and Dec. 31, 2023, is eligible for the program, while funds are available.

Rebates may be claimed immediately and will be awarded up to 90 days from the purchase date. Customers must present receipts and rebate application, which is available at www.derbyks.com/water and at City Hall.

Original copies of the required information must be provided to verify the purchase. Failure to provide the required information will result in the rebate request being denied. The application must include a sales receipt or invoice for the qualifying device. There is a limit of five qualifying devices per City of Derby utility account. Rebates will be credited to the applicant’s utility account.
