Report
Summary
The 24th Street Water Treatment Plant is a conventional water treatment facility with the capacity to treat 140 million gallons per day (MGD). The WTP treats Salt River Project water with various operations and processes. It was constructed in the 1950s and 1960s, and upgraded in the 1990s and 2000s. A condition assessment of the 24th Street WTP treatment systems indicated that various treatment systems are deteriorating and are in need of rehabilitation/replacement, due to age and usage. The City anticipates the treatment systems to be rehabilitated/replaced include flocculation basins, sedimentation basins, junction boxes, other concrete structures, filter valves, raw water inlet pipelines, sludge blowdown pipelines, main switchgears, and other electrical equipment.
Kiewit Infrastructure West Company will begin in an agency support role for the CMAR Design Phase Services and will then act as the construction contractor for the City during the Construction Phase Services for the project. The CMAR Design Phase Services may include, but are not limited to providing detailed cost estimating and knowledge of market place conditions; project planning and scheduling; construction phasing and scheduling that will minimize interruption to the City; alternate systems evaluation and constructability studies; and advising the City on ways to gain efficiencies in project delivery.
