Be RainWise -- Manage your rain water at home

03_HouseGSI_180What is RainWise?

More than 450 Seattle homeowners have installed rain gardens and cisterns that are helping to control stormwater runoff and preventing combined sewer overflows as part of the RainWise program in Seattle.

Fall, winter and early spring are great times to start a RainWise project:

  • Plants have time to grow healthy roots and with plenty of rain you don’t need to water them until summer
  • Contractors who install rain gardens and cisterns tend to be more available fall, winter and early spring.
