The $71 million Robert B. Diemer Filtration Plant project was to establish a seismically stable foundation for a new ozone generation facility. Before any production work could begin, a large amount of demolition work needed to be completed, including the existing maintenance building, fueling station, asphalt parking area and duct bank runs.
The $87 million Sacramento River Water Treatment Plant expansion involves increasing the current facility's capacity by 60% to 160 million gallons per day. One of two plants that supply all of the drinking water for the City of Sacramento, the project will be finished in early 2005.
This $70 million project called for construction of the San Vicente Pump Station with three sets of 7,000 hp pumps and motors, surge control facility, and pipelines connecting the San Vicente Pump Station, San Vicente Pipeline, Moreno Lakeside Pipeline, and the San Vicente Interconnect Pipeline. This project was part of the San Diego County Water Authority's Emergency Storage Project and received the American Society of Civil Engineers (ASCE) Outstanding Water, Wastewater & Reuse Project award in 2010.
This $89 million project involved the construction of a 15-million-gallon-per-day water reclamation plant and process facilities for the 2.9 million people in the San Diego area. Just months after award, the client doubled the plant's capacity and selected the on-site Kiewit Pacific Co. team to handle the additional work.
Kiewit Pacific Co. is constructing updates to the Waterman Treatment Plant originally constructed in 1974. The improvements will increase the plant's capacity from 15 million gallons per day to 30 million gallons per day. In an effort to modernize the plant, many of its facilities will be completely or partially torn down and replaced.
Originally constructed in 1956, the Water Pollution Control Plant provides the primary treatment for 36 millions of gallons of wastewater. To improve its wet weather reliability and reduce the need to discharge untreated or under-treated wastewater into the San Francisco Bay, Kiewit Pacific Co. constructed upgrades to the plant.
Kiewit Southern Co. was awarded the $11 million project to design and construct the Pembroke Pump Station. The team constructed an at-grade precast panel pump station, four 40-cubic-feet-per-second pumps with 30-inch-diameter expansion joints, back-flow gates and butterfly valves that are connected to a 64-inch-diameter steel header pipe.
The $9.5 million rehabilitation project included the complete removal and rehabilitation of seven horizontal, axial flow pumps. For the Pump Stations S7 and S8 project, Kiewit also had to re-machine the propellers and replace bearings, reconfigure the pumps basins, and a telemetry package.
