Reliable services

We are dedicated to providing reliable and efficient wastewater service and treatments, along with protecting our community’s health and environment.

About our wastewater system

Vancouver’s effective and efficient wastewater collection system includes approximately 785 miles of total sewer lines and 41 pump stations. These pumping stations provide a means of moving wastewater from areas lacking gravity sewer lines to an adjacent area where gravity lines exist. The total size of our collection system expands each year due to growth. As of mid 2023, the City of Vancouver sewer district serves almost 244,000 residents across a 58.6 square mile area. Our two wastewater treatment facilities, which serve those customers well, have been recognized for their environmental excellence.

Ongoing coordination of services with Clark Regional Wastewater District

The City of Vancouver and Clark Regional Wastewater District have approved two new wastewater treatment and services agreements aimed at providing service flexibility, rate protection and future stability for sewer customers of both agencies and district employees. The agreements basically change the relationship between the two agencies from customer-treatment provider to partners.
