Anaheim Public Utilities is rehabilitating the Lenain Water Treatment Plant. This plant treats water that is imported from the Colorado River and stored in Anaheim’s Walnut Canyon Reservoir. The treated water from the plant serves residences and businesses throughout Anaheim, providing water supply and meeting maximum day water demands. The plant includes the water treatment facilities, an operation and control center, and a water quality lab. The plant was last upgraded in 1996 and improvements are needed to replace aging infrastructure and improve safety and security.
This project will replace outdated equipment such as valves, electrical controls, and pumps in the treatment plant as well as valves in Walnut Canyon Reservoir, retrofit facility structures to meet current seismic codes, install a back-up power generator, improve the access road, install surveillance cameras, construct new pipelines, and replace the pavement on the boat ramp. The project will also include construction of a new storage building adjacent to Walnut Canyon Reservoir to house the controls for valves and chemical feed systems.
