Water Reuse System
Santa Rosa's Regional Water Reuse System is comprised of eight sections that operate and maintain the Laguna Treatment Plant, Compost Facility, and the Recycled Water Distribution System.
- The Laguna Treatment Plant is a tertiary-level treatment facility that has an average daily dry weather flow of 17.5 million gallons per day.

This facility serves the Subregional partners including the Cities of Santa Rosa, Sebastopol, Cotati, Rohnert Park and the Sonoma County South Park Sanitation District.
- The Oakmont Treatment Plant has an average flow of .5 to .6 MGD and operates between April and October. The Subregional Compost Facility is an agitated, aerobic, naturally heated, biological process that produces approximately 12,000 cubic yards of compost annually.
- The Reclamation system comprises 6,130 acres and utilizes 45 pump stations that deliver reclaimed water to the buried pipe and above-ground irrigation systems
