RV Dump Stations

Recreational Vehicles (RV) Sanitary Dump Stations are provided at select Safety Rest Areas (SRA) for use by private RV owners, and not to be used by commercial vehicles. Construction and Maintenance of the RV Dump Stations is funded through RV licensing taxes. RV Dump Stations at SRAs are open all year long west of the Cascades. An update to the current RV Dump Station design is underway which will ensure stations are open all year long east of the Cascades as well.

Recreational Vehicle Citizens Advisory Committee

The department uses a volunteer citizens group of recreational vehicle users to help define the needs of the RVs at rest areas. RV Committee suggestions guide the department in adding and improving the RV Dump Stations. They also provide guidance on the expenditure of funds from the RV account and RV account fee adjustments.

The department may increase the RV account fee after consultation with citizens representatives of the recreational vehicle user community. The fee cannot be adjusted more than once every four years. The fee adjustments must be preceded by an evaluation per RCW 46.16.063.
