INLAND EMPIRE AWARDED CMS THEIR RP‑4 PROCESS IMPROVEMENTS PHASE II PROJECT

The Inland Empire Utilities Agency (IEUA) is a regional municipal water district serving 242 square miles of western San Bernardino County with wastewater treatment, solids handling, and recycled water services. Its system supports multiple cities, unincorporated communities, and state facilities, and is overseen by a publicly elected five-member board. IEUA operates five regional water recycling facilities across two service areas, with centralized solids treatment at RP-1 in the north and RP-2 in the south.

The RP-4 Process Improvements Phase II Project is a strategic reinvestment aimed at improving the reliability, efficiency, and long-term performance of the Rancho Cucamonga treatment facility. The work will rehabilitate aging secondary and tertiary systems, enhance operational redundancy, and integrate new electrical, instrumentation, and control components to support future capacity and regulatory requirements.

MWH was selected to deliver full Construction Management Services, supported by a team deeply familiar with IEUA’s facilities and operational standards. Led by Dave Dismang, Construction Manager Michael Dietrick, Principal-in-Charge Ray Montoya, and Inspector Robin Foulon, the team brings more than 150 years of combined water and wastewater experience and a long history of on-site support at IEUA.

This project reflects the growing strength of MWH’s Construction Management Services group and demonstrates the team’s ability to manage complex, multi-phase treatment plant rehabilitations while maintaining continuous operations. With integrated project controls, commissioning resources, schedule expertise, quality oversight, and senior leadership involvement, MWH provides IEUA with a high-performance Construction Management team focused on delivering reliable, consistent, and innovative results.
