Being a good neighbor during construction
Wastewater system - under construction
King County is undertaking a number of projects in the coming years to expand and improve our regional wastewater treatment system. Some of the projects are part of the Regional Wastewater Services Plan, a 30-year plan to protect public health and the environment in our region, while others are simply routine maintenance or upgrades.
What can neighbors expect?
Construction sites for Wastewater Treatment Division projects are busy. Crews could range from three or four people to a dozen or more depending on the size of the project.
Heavy equipment like backhoes, cranes, cement trucks and generators are common, and this equipment does generate noise. People might also see specialized equipment being delivered to the site, like a tunnel boring machine. While work is taking place, excavation and earthwork activities tend to create dust or mud. Construction vehicles and possible road closures or detours could affect traffic.
Before construction starts, King County staff routinely holds small neighborhood meetings to discuss the project and answer questions for construction site neighbors. When construction starts, near neighbors will always have a point of contact for asking questions or reporting concerns.
What's going on out there?
The Wastewater Treatment Division undertakes several types of projects to ensure our treatment system stays efficient and has enough capacity.
