What We Do


We plan and construct projects that meet the needs of our communities and work to keep up with the impact our growing population has on our infrastructure. We also work with developers and property owners to ensure new structures are built to last.

Garbage & Recycling

We operate the only solid waste disposal facilities in Thurston County and provide essential tools for waste reduction to our communities.

Parks & Trails

We ensure our communities have well-kept parks and trails and protect open spaces for future generations to enjoy.

Road Operations

Paved roads make up the most significant part of Thurston County’s transportation system. Our work is crucial to maintaining the investment we have made in our roads.

Water Resources

We manage stormwater runoff, mitigate flooding, and provide clean drinking water and sewage treatment for a cleaner, healthier environment. We help manage noxious weeds and facilitate healthy lake programs.
