In 2021 Anaheim Public Utilities rehabilitated the Lenain Water Treatment Plant by replacing outdated equipment such as valves, electrical controls, pumps in the treatment plant, and valves in Walnut Canyon Reservoir. In addition, we retrofitted facility structures to meet current seismic codes, installed a back-up power generator, improved the access road, installed surveillance cameras, constructed new pipelines, and replaced the pavement on the boat ramp. The project also included construction of a new storage building adjacent to Walnut Canyon Reservoir to house the controls for valves and chemical feed systems.
