    We help you keep it clean.

    Healthy septic systems are good for your family, your wallet and the environment. With just a few simple steps, you can protect your septic—and avoid costly repairs. Your groundwater and Puget Sound lakes, rivers, and beaches benefit, too!

    What is a septic system?

    Think of them like a sewage treatment plant, only much smaller.  They store, treat and dispose of the things you flush or send down drains. There are many different types of systems. Some are simple, using only a tank and a drainfield.  Others are more complex, requiring pumps, filters, or specially designed materials.

    A maintained septic system keeps you and the environment healthy and helps:

    • Reduce the risk of people getting sick from untreated sewage.
    • Reduce the risk of contaminating groundwater and surface water.
    • Save you money and extend the life of your system.

    Our role is to:

    • Work with septic system professionals to approve system design, location and installation.
    • Educate property owners to make sure their septic system gets proper maintenance.

      What are the regulations?
