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. […]
This project consists of an installation of six vertical turbine pumps capable of pumping 600 gpm at 500 psi. The system has two surge tanks and high pressure control valves.
Installed three 50 horsepower pumps, two masonry buildings with wood framed roofs (one pump house, one chemical building), chemical building installation with chemical feed system for chlorine, phosphates, and ammonia, including chlorine analyzers and dosage pumps. Yard piping included the installation of approximately 500 lineal feet of 12-inch and 16-inch ductile iron pipe. Installed connections […]
Construction of one 15,000 gpm ultimate capacity recycled water booster pump station including appurtenances and converting an existing potable water reservoir to a recycled water reservoir.
