MWH (Joint Venture Partner)

The Sunol Valley Water Treatment Plant [SVWTP] Phase II Improvements Project was a critical project in the SFPUC’s 10 year Capital Improvements Program [CIP] and one of the agency's largest and most complex projects at the time of completion.  Phase II increased the capacity and reliability of the existing plant and involved the construction of a new treated water reservoir (TWR), chlorine contactor structure and all related piping, as well as structures and systems related to the addition of 40 MGD treatment capacity to the existing SVWTP Facility. Located less than half a mile away from the active Calaveras fault, the site is located in a seismic hazard zone.

As a Joint Venture partner, AGS provided civil, geotechnical, and structural design services for expansion of the WTP and the new TWR.  AGS’ scope of work also included lead civil and pipeline design, geotechnical investigations and recommendations for the design and construction of the facilities and proposed structures, pipelines and other related improvements. AGS’ construction administration services encompassed the inspection of the drilled piers supporting the reservoir and the soil nail wall construction.

The JV Team was recognized by the American Public Works Association with a Project of the Year Award, Environment category (2014).
