Stantec has been selected by the Inland Empire Utilities Agency (IEUA) to lead the design of a new pump station and an 11-mile recycled water pipeline to support long-term water supply reliability in Southern California.
The infrastructure will convey recycled water from the City of Rialto’s wastewater treatment plant to IEUA’s proposed advanced water purification facility in Rancho Cucamonga, strengthening regional water resilience in San Bernardino County.
Recycled water infrastructure to boost supply reliability
The new pipeline and pump station will be designed to deliver up to 10 million gallons per day of recycled water. Water reuse forms a central part of IEUA’s Chino Basin Program, which aims to diversify water supplies and reduce reliance on imported water sources.
Stantec will act as design lead for the progressive design-build project, working in partnership with construction contractor Rados. The scheme includes new conveyance infrastructure, pump station facilities and connections to both the existing Rialto wastewater treatment plant and the future advanced water purification facility.
Supporting long-term regional resilience
The recycled water pipeline will pass through several communities, including Rialto, Fontana, Bloomington and Rancho Cucamonga. Delivery of the project will require coordination with local authorities, utilities and stakeholders to integrate the new infrastructure into existing networks.
The project is scheduled for final commissioning and completion by 2031 and is expected to play a key role in supporting IEUA’s long-term objectives for water reuse, sustainability and supply resilience.
Proven design-build partnership
Stantec and Rados have previously collaborated on a number of complex water infrastructure projects across California, including the North Valley Regional Recycled Water Program in Modesto and the 4th Street Interceptor project in San Jose.
IEUA is widely recognised for its leadership in water reuse and integrated resource management across the Inland Empire region.
