Do your part on rainy days
What you can do to Protect Our Waters
Disconnect downspouts
In some older Seattle neighborhoods, stormwater from roof drain downspouts and foundation drains flows into sewers. In other areas, these connections are not allowed.
Homeowners can disconnect roof drain downspouts, yard drains, and sump pumps from the sewer system and redirect them to a separate stormwater system.
Install a rain garden, cistern, or other green stormwater infrastructure
Disconnected downspouts can be directed to a rain garden or cistern.
King County has three programs that may pay all or part of the cost:
- In the oldest Seattle neighborhoods where sewage and stormwater are combined in the same pipe: RainWise
- Elsewhere in King County’s sewer system area: Green Stormwater Infrastructure Mini Grants . (This program is managed by Stewardship Partners with funding from King County.)
- In Unincorporated King County: RainScapes
Find out if your address is eligible on each program’s website.
Repair leaky side/home sewers
Every property has one sewer pipe that connects the building(s) to the larger sewer and treatment system. Groundwater seeps into sewer pipes through holes, cracks, and joint failures in pipes. Repairing your leaky side/home sewer will keep water out of the sewer system and reduce the chance of overflows. These repairs can use trenchless technology, such as pipe bursting, which has fewer impacts to existing landscaping.
Prevent pollution
When residents Don’t Flush Trouble, they help keep trash from entering the waterways during an overflow. You can also help keep pollutants out of our streams, lakes, and Puget Sound:
- Don’t use pesticides
- Fertilize moderately
- Clean up pet waste
- Keep soap, cleaners and paints out of storm drains
- Fix oil and fluid leaks in cars
