County Sanitation District 1 (CSD-1) provides wastewater collection services to about 269,000 connections in the Sacramento, California region. CSD-1 has nearly 2,800 miles of mainlines and collectors and operates 95 sewer pump stations. CSD-1 has implemented a risk based asset management program in both the pipeline and pump stations areas of the collection system. Though the two strategies are significantly different, they are both based on the common idea of
incorporating dollar-based risk into maintenance decisions. This paper will describe CSD-1’s mechanical maintenance strategies and will share some lessons learned in the process.
