Diamond Regional Sewer Lift Station & Dual Force Mains

Garney is improving wastewater management in Lake Elsinore, California, to support the region’s rapid growth by transitioning homes from septic to sewer systems and expanding wastewater capacity. The project features a new sewer lift station designed by Carollo Engineers and the installation of dual 18-inch and 26-inch HDPE force main designed by Kennedy Jenks.  

Solutions

Force Main Rerouting: Strategically planned to avoid right-of-way conflicts, minimize public disruption, and enhance safety.

Warren Epoxy Lining: Installed in place of a T-lock within the wet well, saving $112,000 and accelerating the schedule.

Thermal Control: Repurposed groundwater from dewater operations to cool mass concrete, reducing environmental impact.

Welding & Dewatering: Addressed groundwater intrusion and shoring challenges with additional wells, in-shore sheet pile welding, and geofabric rock reinforcement to ensure safety and stability.

Project Status

The team recently completed the Jack and Bore and the dual force main is expected to be finished by year’s end. The sewer lift station is nearly backfilled, and sheet piles will be removed in December. Garney looks forward to completing this project this coming year and is most proud of building a dynamic project while maintaining a perfect safety record.
