Rincon del Diablo Municipal Water District

What Rincon del Diablo Municipal Water District does

Rincon del Diablo Municipal Water District is a California special district, organized under the Municipal Water Act of 1911, providing potable water, recycled water, sewer collection, and administrative oversight of fire protection services across a 42-square-mile service area in the Escondido Valley (portions of Escondido, San Marcos, San Diego, and unincorporated San Diego County). The district serves approximately 32,000 residents through more than 8,000 water service connections across two improvement districts (ID 1 covering 7,945 acres and ID A covering 1,120 acres), 4,250+ fire protection customers, and 750 sewer parcels in the Harmony Grove Village service area. Infrastructure comprises nine enclosed reservoirs with 22.5 million gallons of storage, over 117 miles of potable water pipeline, nearly seven miles of recycled water pipeline, and four pump stations, with peak production capacity of 10 million gallons per day.

The district's technology stack centers on an Advanced Metering Infrastructure (AMI) radio-based meter reading system that transmits hourly usage snapshots, a computerized telemetry system for water production management, ESRI-based GIS mapping for infrastructure and spatial analysis, and a WaterSmart customer portal for usage tracking, leak alerts, and account management. Water supply is diversified across imported Colorado River water (via MWD and SDCWA aqueducts), Northern California State Water Project water, local Lake Henshaw water (ID A), and since 2016 desalinated seawater from the Carlsbad Desalination Plant blended at Twin Oaks Valley Water Treatment Plant.

Revenue is generated through monthly tiered potable and recycled water rates plus a fixed Systems Operations Charge (multi-year plan adopted June 14, 2022), annual sewer service charges levied on property tax bills (FY 2025-26 through FY 2029-30 schedule adopted), one-time sewer capacity fees ($10,350 per EDU), and fire protection service oversight under a long-standing agreement with the City of Escondido Fire Department. The district is governed by an elected five-member Board of Directors, holds an inaugural AA+ public credit rating (January 2026), and was recognized with the GFOA Excellence in Financial Reporting Award in 2024. Leadership transitioned in March 2026 with the appointment of Jeff Umbrasas as General Manager.
