Central San Previews $271M Budget With $155M Capital Push and 4% Rate Hike

The Central Contra Costa Sanitary District board received its most comprehensive fiscal blueprint of the year Wednesday — a $271 million spending plan for FY 2026-27 that pairs a 4% sewer rate increase with one of the largest capital programs in the district's history, anchored by $155 million for treatment plant upgrades, collection system rehabilitation, and regulatory compliance.

• $271M budget heads to adoption June 4 with a 4% sewer rate hike adding roughly $30/year for single-family customers and $25 for multifamily

• $155M capital program climbs 7.8%, targeting solids handling, UV disinfection, pump stations, and 8+ miles of sewer rehabilitation

• 10-year infrastructure outlook tops $1.4 billion as the district pursues nutrient removal, PFAS readiness, and a potential Mountain View Sanitary District consolidation

• District lands ~$50M in state revolving fund financing at sub-1% interest for UV disinfection — roughly half the project's construction cost

• Concord City Council approves Navy financial deal that could unlock demand for Central San's recycled water program

The basics: Central San treats 34 million gallons of wastewater daily through more than 1,500 miles of pipe for a service area spanning much of central Contra Costa County. The FY 2026-27 budget breaks into four funds: operations and maintenance ($106.1 million), capital improvements ($155 million), self-insurance ($2.83 million), and debt service ($9.3 million). Formal adoption is scheduled for the June 4 board meeting.
