Sukut Construction, LLC

Butier Engineering, Inc. was selected to provide construction management and inspection services for the construction of the Trampas Canyon Dam and Reservoir. The dam and reservoir are being reconstructed to create a 1.6 billion gallon (5,000 acre-foot) recycled water reservoir, which will provide seasonal and operational storage for Santa Margarita Water District’s (SMWD) existing and proposed recycled water system. The reservoir will supply irrigation demands for customers in Talega Valley and in Rancho Mission Viejo’s (RMV) ongoing Ranch Plan development, as well as other existing irrigation demands in South Orange County. Recycled water will be supplied by the Chiquita Water Reclamation Plant (CWRP) and may be supplemented with other non-domestic water (NDW) supply sources. In addition, the proposed reservoir may provide storage for other recycled water purveyors in South Orange County.
