Pierce County receives 38-56 inches of rain per year. That rain usually flows off of hard surfaces, like roofs, driveways and streets, into the stormwater system. The stormwater system sends runoff through ditches or pipes to local waterways. Runoff picks up pollutants like oil, heavy metals, animal waste, fertilizers and toxic chemicals along the way. That was is not treated before it is released into streams, lakes, rivers and Puget Sound.
How Can You Help?
Homeowners can take simple actions on their property to encourage rain to soak into the ground and reduce the amount of runoff leaving their property. These actions can reduce flooding, save money, and decrease pollution in streams, rivers, lakes and Puget Sound.
