City of Somerton Valley Vista Wastewater Collection System

Somerton, AZ


PACE was engaged by the City of Somerton to provide design services for a new lift station and installation of a new sewer collection system that redirect flows to the newly upgraded Somerton Wastewater Treatment Plant (WWTP). The new lift station was constructed adjacent to the existing lift station to minimize infrastructure costs, such as connective piping and electrical services. The system required 8,700 linear feet (approximately 1 mile) of pipe to traverse from the Valley Vista WWTP Lift Station to the Somerton WWTP.


This design was selected as the best alternative for the project based on positive revenue stream, reduced operations and maintenance (O&M) cost, low life cycle cost, and minimized impacts to the surrounding environment. PACE prepared a U.S. Department of Agriculture – Rural Development (USDA-RD) Preliminary Engineering Report (PER) and Engineering Report, and the USDA-RD offered loan / grant combination funding to the City and County to complete the project.
