The cities primary source of water is obtained from the Big Canyon Reservoir in conjunction with several wells through out the city. Prior to putting the water into distribution two disinfectant chemicals are injected into a 42” water main. Since the 42” main branches after the proposed injection location and the flow to each branch […]

The City of Pomona obtains most of their potable water from underground wells. Like most underground water sources they are contaminated and must be treated before being distributed. Some of the contaminants included perchlorate and nitrates. The city has used their anion exchange plant (AEP) to removed these contaminants which is feed by fifteen wells. […]

The work consisted of the construction of a fuel cell generation system including two 300-kW fuel cell power plants; two hot water heat recovery units; one anaerobic digester gas treatment skid; one dual fuel boiler system including equipment pad; two canopies; three digester gas boosters; three hot water recirculation pumps. All systems were connected to […]

This project was done in co-operation with R. C. Foster Corporation, who acted as the general contractor. We formed and poured 8,500 cubic yards of structural concrete for a potable water treatment facility. Almost all of the concrete poured was 5500 psi, shrinkage controlled, low water-cement ratio materials that utilized high range water reducers due […]

In October 2009, a cold spell and strong winds cooled the warmer, more highly oxygenated water on the surface of the Upper Oso Reservoir in Rancho Santa Margarita, CA. The cooled water sunk to the bottom, bringing less-oxygenated water to the top. The “flip” produced an algae bloom and led to the release of hydrogen […]

This project consisted of the construction of a 3.5 million-gallon DYK pre-stressed reservoir.  Pipelines and appurtenant site work was completed as part of the overall contract. (Photos by: Warren Aerial Photography, Inc.)

This project consisted of the construction of a 1.5 million-gallon DYK buried pre-stressed reservoir on a steep hill side site.  We also completed a booster pump station and an award winning City Park over the top of the reservoir. (photo by: Jeran Aero Graphics Inc. San Diego)

This project consisted of the construction/installation of a 5 pump pump station, engines and motors, chemical treatment system, building, bridge crane, and site work.

Installation of two separate pump stations located at the same site. One pump station was designed for use as a domestic water station, the second for reclaimed water. The reclaimed water station included the construction of a concrete structure approximate 2,000 square feet in area and 20 feet deep. A total of eight vertical turbine […]

This project consists of a deep excavation for the installation of a below ground pump station.  SEC excavated and shored a pit approximately 25 feet deep with piles and steel plates.  The pump station was then built inside the pit and consisted of three vertical turbine pumps capable of pumping 750 gallons per minute each.  […]
