Stormwater Pump Replacement and Drainage Box Construction
Location: San Jose, CA, and Morgan Hill, CA
Project Scope: Stormwater storage box construction and pump station equipment replacement
Disney was contracted by Caltrans to construct new stormwater storage boxes and replace pump station equipment in San Jose and Morgan Hill. The project included building two new reinforced concrete storage boxes with associated storm drain piping and drainage inlets at Alum Rock in San Jose, as well as replacing all electrical and mechanical equipment at two existing pump stations in Morgan Hill.
Unique Challenges: Coordinating simultaneous civil and mechanical work across multiple sites while maintaining continuous storm water system functionality.
Permanente and Hale Creek Channel Repairs
Location: Mountain View, CA, and Los Altos, CA
Project Scope: Concrete channel repair and structural strengthening
Disney was contracted by the Santa Clara Valley Water District to repair and strengthen the Permanent Creek and Hale Creek concrete channels. The project involved repairing concrete spalls and cracks and installing new steel braces along approximately 1,700 linear feet of channel.
Unique Challenges: Executing structural repairs within active drainage channels while maintaining flow capacity and minimizing environmental impacts.
Curtner Rd Booster Station Upgrade
Location: Fremont, CA
Project Scope: Demolish and rebuild the 50-foot deep Curtner Rd pump station
Disney was contracted by Alameda County Water District to perform the upgrades on the Curtner Rd Booster Station. The project included demolishing the interior concrete, steel, and mechanical piping and building new floors, stair access, mechanical piping system which included four vertical turbine pumps and a new electrical pad located outside of the station.
Unique Challenges: Working in a deep confined space with limited space for equipment.
SMD1 Sewer Conveyance Pump Station
Location: Placer County, CA
Project Scope: Build a pump station
Disney was contracted to consolidate wastewater treatment in the first part of a three-part project for the Mid-Western Placer Regional Sewer Project. The work entailed: completion of pump station, odor control facility, emergency containment basins, MCC and standby generator, modifications of headworks, site grading, and yard piping.
Unique Challenges: Use of new, large pumps that needed to pump up to ten miles away, tight timeline to upgrade pumps or pump around them.
Dyer Reservoir South Bay Aqueduct Enlargement
Location: Livermore, CA
Project Scope: Build canal and concrete structures
Disney was contracted to build a canal as part of the State Water Project (SWP) to enlarge the reservoir in order to receive water from the South Bay Pumping plant at night during ‘off-peak’ hours. The unique design allows the water to flow to Bay Area communities by gravity, resulting in cost savings to the state and to consumers. The work entailed: building all concrete structures and the canal.
Unique Challenges: Building unique and complicated concrete structures.
Knights Landing Outfall Gates
Location: Colusa Basin Drain
Project Scope: Constructing positive fish barriers
Disney was contracted to make improvements to the Knights Landing Outfall Gates and maintain outflows and water surface elevations. This was part of an improvement action to protect salmon and prevent them from entering the Colusa Basin Drain, from which they can’t escape. The work entailed: constructing a positive fish barrier and new concrete wing walls, installation of a metal picket weir, and riprap placement.
Unique Challenges: Working in an environmentally sensitive area.
