Hydroelectricity

OMWD operates two hydroelectric facilities.

Roger Miller Reservoir

Roger Miller Reservoir

The original plant is located at the Roger Miller Reservoir in the hills above Encinitas. This plant uses high-pressure water delivered from a nearby reservoir to power its turbines. That allows the plant to deliver a peak capacity of 450 kW.

David C. McCollom Water Treatment Plant

The second hydroelectric plant is located at the David C. McCollom Water Treatment Plant. Imported water passes through turbines that convert the hydraulic energy into mechanical energy through direct-coupled blowers and electrical energy through attached induction generators.

OMWD is joined by water agencies throughout California in using hydroelectricity as a power source for its operations. View the Association of California Water Agencies’ video to see how some of those agencies have implemented renewable energy projects and promote energy efficiency.
