Featured Projects

The Problem: The project involved designing and obtaining permits for a uranium treatment facility for the water system at the elementary school in Coleville, California. The process was more complex because approval was required from the California Division of the State Architect since the project was on the Eastern Unified School District’s property. 

The Solution: 

The work included investigations, conceptual design, and a technical report to support the California Department of Public Health permit application. It also involved a detailed design of the treatment, storage, and booster pumping system, which required collaboration with architects, electrical engineers, and structural engineers. Additional services included obtaining grant funding and permits through the California Division of the State Architects and the California Division of Water Resources, which mandated a flood protection berm. Furthermore, construction observation and other services were provided during the construction phase. 

The Results: 

The system includes two water supply wells, a fiberglass tank for storing raw water to feed the treatment unit and landscape irrigation, a variable-speed irrigation pump, a treatment booster pump, and cartridge filters followed by three ion exchange units in series to remove uranium. Treated water is stored in two fiberglass tanks, followed by duplex variable-speed booster pumps to supply the schools. The system features extensive controls and alarms and is housed in a building to protect it from freezing weather. Because the project site is located on an alluvial fan, a flood control berm was built to safeguard this critical infrastructure.
