RiverSmart Rewards and Clean Rivers IAC Incentive Programs

<< RiverSmart home page

Apply for RiverSmart Rewards and receive discounts on your DC Water bill. District residents, businesses, and property owners can earn a discount of up to 55% off the DOEE Stormwater Fee when they reduce stormwater runoff by installing green infrastructure (GI) such as green roofs, bioretention, permeable pavement, and rainwater harvesting systems. GI helps protect the Anacostia and Potomac Rivers and Rock Creek. DC Water also offers a similar incentive program for its customers to earn a discount of up to 4% off the Clean Rivers Impervious Area Charge (IAC).

Using one application, District residents, businesses, and property owners can apply for discounts through RiverSmart Rewards and the Clean Rivers IAC Incentive Program. Discounts are based on the stormwater retention volume achieved and are posted to DC Water bills.

Below is a comparison between the discounts provided by RiverSmart Rewards and the Clean Rivers IAC Incentive Program.
