The Freeport Regional Water Project is a joint water project being developed by SCWA (Sacramento County Water Agency) and EBMUD (East Bay Municipal Utility District) in close coordination with the City of Sacramento and Reclamation. The goal of the project is to address the drinking water needs of SCWA and EBMUD. The Freeport Project will provide up to 100 mgd of water for EBMUD to use during drought years and 85 mgd for SCWA for use in all years. The project will supplement aggressive water conservation and recycling programs in the East Bay and reduce the potential for severe water rationing and associated economic losses and hardships during drought periods. It will provide river water to SCWA to be used in conjunction with groundwater to help meet future drinking water needs in the central Sacramento County area. These future water needs have been identified to support the growth projected in the Sacramento County General Plan and have been recognized as part of a landmark Water Forum Agreement.

AGS, as the geotechnical engineering consultant to the CH2MHill team for design of the intake facilities, performed a geotechnical study which included drilling of 25 off-shore and on-shore borings, laboratory testing, geophysical survey, and preparation of a geotechnical data report.

As a joint venture partner of the MWH/AGS/Structus team, AGS was tasked by SFPUC to design a new water treatment plant and treated water storage reservoir. The project was one of the largest and most complex undertaken by UEB in several years. Phase I of the Sunol Valley WTP Improvement Project increases the capacity and reliability of the existing plant by including a new flow distribution vault, a new flash mix chamber, a new chemical feed building, new office and lab facilities, and seismic upgrade of existing structures.

Geotechnical - AGS performed geotechnical studies addressing issues related to Faulting, Groundwater, Earthwork requirements, Slope stability, Liquefaction, Corrosion potential of pipes, Pavement design, and Foundation design.

Civil - During the planning phase, AGS evaluated drainage alternatives to make better use of existing sludge ponds. The firm was responsible for the site civil design; preparing plans and specifications for site layout grading, roadways, drainage, large diameter process piping and yard piping.

Construction Management - During construction, AGS provided a senior on-site construction administrator who provided multidiscipline design coordination to resolve contractor questions, design changes due to changed field conditions, and expedited RFIs.
