SLO Water Resources Recovery Facility (WRRF)
Originally constructed in 1923, the San Luis Obispo Water Resource Recovery Facility (WRRF) is a wastewater treatment plant located on Prado Road in San Luis Obispo, California. Owned and operated by the City of San Luis Obispo, the WRRF serves the City’s residents, California Polytechnic University, and the local airport. It treats around three million gallons of water per day that is either recycled or discharged back into San Luis Obispo Creek after treatment.
In response to revised Municipal and Domestic Water Supply criteria, and to increase energy efficiency, the City implemented a plan to upgrade the WRRF. Additional project drivers included increasing flow capacity per the City’s General Plan, providing treatment to peak stormwater flows, addressing aging and out-of-date equipment, incorporating features that embrace the value of the WRRF as a community asset, increasing operational efficiency, controlling odor, and increasing recycled water production.
Cannon was selected to provide several services including automation and electrical engineering design for the facility. This design required modifications to an existing SCADA system, implementation of intelligent motor control, upgrades to the existing fiber optic network and components, and integration of multiple advanced treatment package systems. The SCADA modifications increased information management tools, improved redundancy and reliability of PLC and network components, and upgraded alarm notification capabilities.
