CITY OF SANTA ANA CITY OF SANTA ANA REHABILITATION OF WELL 29 Santa Ana, CA Psomas was retained by the City of Santa Ana to provide consultant services for preparation of construction plans and technical specifications for rehabilitation of the City's existing Well 29; the relocation of an existing tennis court; and construction of a cement masonry unit (CMU) building, pertinent related site improvements, and water pumping equipment. In addition to the well pump and redesigned discharge piping, the building will house the electrical switchboard and the pump motor control center. Drilling of the well occurred in 1980, with the subsequent installation of pumping facilities occurring in 1982. Well 29 is one of three wells pumping water from the groundwater basin to the Walnut Street Reservoir as part of the City's Walnut Pump Station System. Due to the age of the well and the deterioration of the well's capacity and equipment, the City wishes to rehabilitate Well 29 and reconfigure the existing site. The City is seeking to improve the productivity of the well by conducting rehabilitation operations, and subsequently placing it back into service. REFERENCE: Armando Fernandez, Sr. Civil Engineer 714.647.3316 1 afernandez@santa-ana.org YEAR COMPLETED: Ongoing WALNUT PUMP STATION UPGRADE Santa Ana. CA Psomas was retained through an on -call design contract with the City of Santa Ana to prepare a preliminary design report, plans and specifications for the construction of new masonry buildings at Walnut Pump Station. Design scope included a new 3,650 SF pump building to replace an obsolete building built in 1956 and enclose five existing vertical turbine pumps. The building architecture was designed using an Art Deco style to match the recently remodeled Santa Ana High School located across the street. The main building included a new pump room, operations workshop, electrical control room, office space, and bath and shower facilities. The design also included a separate 200 SF industrial storage building for sodium hypochlorite and POL fuel, a carport structure to shade a generator, an 8-foot-high CM perimeter wall, and two tennis practice courts and practice walls in the adjacent park to mask the perimeter fencing. Two existing steel supply mains were relocated due to the new building footprint and included design of two new valve vaults. On the City's behalf, Psomas submitted this project through ISI Envision and achieved a Bronze award.
