A shovel-ready regional interconnection led by JCSD in partnership with Fontana Water Company to diversify supplies, improve water quality, and strengthen long-term reliability and affordability for the Inland Empire.

A regional solution for safe, reliable, affordable water

Jurupa Community Services District (JCSD), in partnership with Fontana Water Company, is advancing a regional pipeline and water quality project that will connect systems and create a practical pathway for critical water sharing. This JCSD Intervalley Water Quality & Resiliency Project is a cornerstone investment to diversify JCSD’s water portfolio, reduce reliance on costly treatment of lower-quality groundwater, and strengthen reliability during droughts and emergencies.

JCSD is currently 100% dependent on local groundwater. Our sole source of water supply has been greatly impacted by contaminants such as per- and polyfluoroalkyl substances (PFAS). Addressing PFAS contamination requires advanced and costly treatment infrastructure, placing increasing financial pressure on ratepayers. By strategically connecting systems, this project reduces overreliance on impacted groundwater, improves supply flexibility, strengthens drought resiliency, and helps mitigate the long-term financial impacts associated with treating emerging contaminants.

100% Groundwater Dependency

JCSD relies entirely on local groundwater, limiting flexibility during disruptions and making diversification essential.

Water Quality Pressures

Groundwater contamination, including PFAS, requires costly advanced treatment, increasing long-term financial pressure on ratepayers.

Drought & Supply Volatility

A connected regional network strengthens reliability during drought, heat events, and supply disruptions.

Infrastructure Efficiency

These types of connections reduce duplicative investments by enabling shared resources and operational flexibility.

Project Scope and Components

Phase 1 — System Interconnection Pipeline (Shovel Ready)

  • Construct 17,000 linear feet of pipeline in a single phase
  • Create an interconnection between JCSD and Fontana Water Company
  • Enable access to surplus water and operational flexibility
  • Built to support future regional water contributions (e.g., IEUA, Ontario, CVWD) as feasible
  • Phase 1 cost: $60 million

Future Phases — High-Quality Supply Development in Fontana

  • Develop two potable wells in Fontana where water quality is excellent
  • Target production: 2,500+ gallons per minute per well
  • Well siting supported by geoscience/technical studies
  • CEQA complete for future well development components
  • Includes land acquisition needs for well sites and supporting facilities

Investment and Funding Opportunity

Strategic state and federal partnership can accelerate delivery and reduce local ratepayer burden.

$60,000,000
Phase 1 total project cost (pipeline connection)

The Intervalley Water Quality & Resiliency Project aligns with statewide water reliability priorities and has advanced through environmental review, including CEQA compliance. The project has received $X in funding from X, demonstrating early investment and regional commitment; however, additional partnership support is needed to fully deliver this shovel-ready infrastructure.

Partnership funding will accelerate construction, strengthen regional water security, and help protect long-term affordability for the Inland Empire. This investment supports a practical, collaborative approach to water management – connecting systems so agencies can share resources and respond to disruptions more effectively.

Frequently Asked Questions

JCSD is 100% dependent on local groundwater. Unlike many agencies in the region, we do not have direct access to imported water supplies such as the State Water Project or Colorado River. Diversifying supply reduces risk, improves operational flexibility, and strengthens long-term reliability in the face of drought, regulatory changes, and water quality challenges.

Yes. Phase 1 of the project, the 17,000 linear foot intertie pipeline connecting JCSD and Fontana Water Company, is positioned to begin construction in Summer 2026. Partner coordination is underway, engineering is advancing, and the project is structured to move forward immediately upon funding availability. Environmental review (CEQA) has been completed for the future well components.

Advanced groundwater treatment and pumping are increasingly expensive due to water quality requirements and energy costs. While treatment remains essential, regional interties provide flexibility that can reduce the need for duplicative infrastructure investments. Sharing supplies allows agencies to optimize existing resources rather than independently expanding costly treatment capacity.

Fontana Water Company is the regional partner agency in this project. The connection allows JCSD to access surplus water supplies when available. In the future, the connection could support two-way emergency transfers, strengthening resiliency for both agencies. The partnership is structured to benefit both communities through improved efficiency and rate stability.

The pipeline is designed with future regional integration in mind. Agencies such as IEUA, Ontario, and CVWD may have opportunities to contribute water to the system as conditions allow. The infrastructure creates flexibility for broader regional collaboration over time.

Phase 1 (pipeline construction) is anticipated to begin in Summer 2026 and conclude by Winter 2028. Future phases involving the development of two high-quality wells in Fontana are planned for 2028–2030, contingent on funding and land acquisition.

State or federal partnership funding would accelerate construction, reduce financial burden on local ratepayers, and strengthen regional water reliability. Investment in this shovel-ready infrastructure supports drought resilience, long-term affordability, and economic stability in the Inland Empire.
