We can decrease the amount of polluted run-off that reaches our lakes and rivers by using natural landscaping, paving stones, and gravel, which slowly absorb pollutants and run-off.
Rainwater picks up debris, chemicals, dirt, and other pollutants.
Polluted run-off flows into our lakes, streams, the Spokane River and the Rathdrum-Spokane aquifer.
The combination of cars, homes, people and animals makes polluted runoff one of the biggest causes of water pollution in the country.
Stormwater swales help filter out pollutants before they reach the aquifer.

For run-off I pledge to:
- Use spaced paving stones, bricks, "grasscrete" or gravel instead of cement or asphalt when building, remodeling, or landscaping.
- Place rain gutters so they drain onto grass, gravel, or garden beds – away from hard surfaces that cause run-off.
- Plant native plants in the yard to help filter polluted run-off.
- Never dump motor oil, antifreeze, pesticides or any toxic materials down storm drains or on the ground.
- Help keep community and personal stormwater swales free from debris.
