The On-site Water Reuse Grant Program provides commercial, mixed-use, and multi-family residential property owners with incentives to install water reuse systems. This grant program builds on the Comprehensive Water Reuse Program, which offers a 25% discount to customers who install successful water reuse systems.

Water reuse systems, sometimes called water recycling systems, make more efficient and safe use of rainwater, black water, or gray water when properly designed and operated. The grant program promotes the construction of these systems at both the building-scale and district-scale by covering a portion of efficiency technology capital costs.
