Regional Sewerage Systems

The Regional Sewerage System includes 90 miles of regional sewage interceptors. The sewage lateral pipelines are owned and maintained by the individual contracting agencies. All of the wastewater is treated at the Agency’s Recycled Water Regional Plants, which provide advanced tertiary treatment that meets or exceeds all California Department of Public Health Services (Title 22 regulations) and Resources Water Quality Control Board’s waste discharge permit requirements.

New industrial customers with high Total Dissolved Solids (TDS) should contact the city or sewerage agency where your industry is located to discuss treatment and discharge options.
