Wastewater Collection and Pump Station System
The wastewater collection system provides sewer service to more than 28,000 households and 2,300 businesses in the cities of Lakewood, University Place, Steilacoom, Milton, and unicorporated areas of the County including Spanaway, Parkland, Brown's Point, South Hill, and Frederickson.

The Sewer Service Area includes the above areas and the entire Urban Growth Area (UGA) as established by the Pierce County Comprehensive Plan. This plan, adopted in 1994, established two basic types of zoning, Urban and Rural. Urban based zoning is all located within the County's UGA. It is within this UGA that all new sewer construction and extension currently exists. Extension of sewer services into Rural areas of Pierce County is not allowed by state and county ordinances.

Pierce County's sewer service area includes:

• Over 631 miles of sewer pipelines
• 94 individual pumping stations
• Over 840 residential grinder pumps
• Over 14,000 service manholes

Wastewater Collections staff constantly monitor the condition of the sewer system using radio telemetry and alarm systems. They maintain the system and respond to emergency calls 24 hours a day at (253) 565-3440.
