Regional wastewater district and county detail sewer projects, annexation and developer work causing multi‑week closures

Clark Regional Wastewater District staff briefed residents on multiple sewer projects that run parallel to the 179th corridor work and on a recent annexation into the district's service area.

"This map shows projects where there's something actively happening," said Les McDonald, the district's planning and development program manager, pointing to active work areas east of I‑5. He said green areas on the district map represent projects that are permitted, under construction or nearing construction and that blue areas represent earlier‑stage interest.

McDonald said the district just completed an annexation request that the county council approved this week; annexation expands the district's service boundary so property owners can seek sewer connections through the district's process. He described recent installations including the Whipple Creek East pump station and a trunk force main, and he discussed how developer projects tie into the county's road projects to coordinate sewer installation.

One audience exchange addressed a private developer project on 50th Avenue; county staff earlier explained contractors are installing a 25‑foot deep sewer that will require an approximately 80‑day closure of 50th. Residents pressed for details about where trucks will route and about safety and monitoring of the contractor; county staff and the district said they will coordinate inspections and staging plans.

Residents also asked whether they could attach homes directly to a nearby pressurized force main. McDonald said force mains are pressurized and not generally suitable for direct residential tie‑ins; gravity systems and the district's connection process determine eligibility. When asked where the sewage goes, McDonald said treated flows ultimately route through the Salmon Creek wastewater treatment plant in the regional system.

The district offered contact information and said staff will follow up with homeowners about parcel‑specific connection questions and with developers to coordinate timing with county roadway work.
