RainWise
Private property owners can be part of the stormwater pollution solution
With every storm, rain carries pollutants off our roofs, driveways and other hard surfaces. These pollutants end up in our creeks, the Duwamish River, our lakes, and Puget Sound. During big storms, the sheer volume of this “stormwater” can cause sewer overflows and polluted runoff.
RainWise helps private property owners install rain gardens and cisterns to help manage the rain that falls on their roofs. These installations can also add attractive landscaping, provide water for summer irrigation, and may reduce flooding.
Check out 700milliongallons.org to find out if you qualify for rebates, see examples of rain gardens and cisterns, and learn more about how to get RainWise.
