save on your water bill in exchange for reducing polluted water in our rivers?


1. Learn about this resource. 

Residents, businesses, and property owners can save money on their DC Water bill when they help reduce pollution from runoff with green projects, such as green roofs, permeable pavement, rain gardens, and rain barrels, on their property. We—DC Government—offer up to 55% off your DOEE Stormwater Fee and up to 20% off the Clean Rivers Impervious Area Charge depending on how much stormwater runoff your green projects prevent.


This program is called RiverSmart Rewards and is offered by the Department of Energy & Environment.

2. Check if you are eligible.

You are eligible if all of these statements are true:

  • You or someone in your household is a current DC Water customer. Your DC Water bill includes the Stormwater Fee and Clean Rivers Impervious Area Charge.

  • You are up-to-date on all your DC Water bill payments.

  • You have installed and continue to maintain one or more eligible types of green projects on a property in DC:

    • Green roof to support the growth of plants that hold rain,

    • Rain barrel or cistern to catch and store rain to use later to, for example, water your garden,

    • Permeable pavement system to capture and temporarily store rain in place of an asphalt, concrete, or brick surface,

    • Rain gardens or similar system to collect rain and filter out pollution,

    • Shade trees to help hold rain in the soil, or

    • Disconnected downspout to redirect drains to your lawn instead of pavement.
