Capital Improvement Program

Spokane County’s wastewater collection system has grown dramatically over the last several decades. The county now owns and operates more than 698 miles of sewer lines and 34 pump stations.

The purpose of the Six-Year Sewer Construction Capital Improvement Program (CIP) is to delineate the county’s sewer improvement priorities and associated expenditures and financing for 2023 through 2028.
