Rancho California Water District
Temecula, California USA
The Santa Rosa Water Reclamation Facility was constructed on a 1,000-acre site. The project utilizes the Sequencing Batch Reactor (SBR) technology to allow wastewater to be converted to reclaimed water through the multi-biological functions that occur within a single concrete tank that is housed indoors. This method of treatment utilizes less property for the primary stages of sewage treatment and eliminates impact to the community and the environment. This facility further refines the wastewater effluent through a tertiary level of treatment utilizing gravity-flow sand filtration to create a chlorinated reclaimed water product that is then distributed directly to irrigation systems within the community.

City of Beverly Hills Department of Public Works
Beverly Hills, California USA

The Beverly Hills Reverse Osmosis Water Treatment Plant is located within a 45,000 square foot Class-A office building. The concept was developed to provide a water treatment facility that would receive raw groundwater pumped to the facility from a city-owned well field. The water is purified through the reverse osmosis method of water purification and then distributed to water storage reservoirs within the city’s potable water storage and distribution system. The project is unique because it was developed within the same building that houses the city’s public works administration and operations offices, eliminating the expose of a water treatment plant to the sensitive appearance of the Beverly Hills community.

City of Escondido Public Utilities
Escondido, California USA

The Parkhill Reservoir was designed as a 6.0 million gallon potable water reservoir replacement to an existing reservoir constructed in the 1940’s. The new reservoir is a reinforced-concrete design with a rectangular shape and a center dividing wall, creating a two-cell reservoir that allows flexibility in city water operations. The reservoir was carefully constructed with portions of the existing circular tank remaining in tact to serve as a retaining wall to support the adjacent roadway on this very confined site. The booster pump station was then constructed to provide a pressurization system for the new water storage prior to distribution into the Parkhill community.

City of Moorpark Public Works
Moorpark, California USA

The Moorpark Wastewater Treatment Plant was designed to increase the capacity of the existing treatment plant from 3.0 million gallons per day (MGD) to 10.0 MGD. The process utilizes a fine-bubble diffusion aeration technology that consists of the installation of hundreds of underwater diffusers that are supplied with process air to provide an air supply to feed micro-organisms that digest the raw sewage in large open-air concrete-lined basins. The clear effluent water is removed and further processed into reclaimed water for distribution to a re-use irrigation system within the community. The heavier waste sludge that settles to the bottom is then removed from the basins, dewatered, and processed into a fertilizer additive that is used for agriculture and landscaping needs.
