Ardurra GroupThe challenge
Constructing the Santa Margarita Conjunctive Use Facility required building an advanced water treatment plant while addressing complex site and infrastructure conditions. The project involved managing sophisticated treatment processes, remediating more than 16,000 cubic yards of contaminated soil and installing nearly 12,500 linear feet of 24-inch cement mortar lined and coated welded steel pipe along county roads and district easements. Work also occurred near residential areas, requiring coordination with the surrounding community.

Challenge met
To overcome these challenges, the project team coordinated construction of the advanced treatment facility and its supporting infrastructure. The work included installation of iron and manganese removal systems and reverse osmosis treatment processes designed to treat local groundwater supplies.
Filanc also constructed a 4-million-gallon steel water tank and booster pump station that integrate the facility with the district’s existing distribution system. Installation of the large-diameter transmission pipeline connected the facility to the district’s infrastructure while maintaining service to surrounding neighborhoods. Through careful planning, soil remediation and coordination with the Fallbrook Public Utility District and nearby residents, the project delivered a new water supply facility that reduces reliance on imported water and strengthens long-term water reliability for the community.
