The Valencia Water Reclamation Plant of the Los Angeles County Sanitation District (LACSD) is a wastewater treatment plant serving over 130,000 people. It provides primary, secondary, and tertiary treatment to upwards of 21 million gallons of wastewater daily. Schneider Electric Energy and Sustainability Services (ESS) will help LACSD reduce energy costs by reducing energy usage at the Valencia Water Reclamation Plant. ESS oversees a large team of design and construction partners, including Enterprise Automation, who helps support the project’s design, construction, and project management requirements.
ESS completed an audit of the Valencia Water Reclamation Plant to uncover energy conservation measures (ECMs) throughout the facility. Each was treated as a separate project, with the scope of work ranging from full system upgrades, and application of advanced process control software, to replacing motor control centers (MCCs). LACSD was able to justify several upgrades due to energy savings and return on investment.
Many of the ECMs required upgrades to their existing control systems and control panels. More modern solutions were developed that included new programming approaches, and a new real-time control system (RTC). The RTC is fully automated optimization software that sits above the SCADA and PLC system. It uses data from the control system to make high-level decisions to reduce energy use and create better process conditions. Key points in the control system are adjusted.
With their deep level of expertise in the water/wastewater industry, EA was originally brought in as a high-level consultant for project I&C and controls oversight to support the design and construction phases. As an extension of the ESS engineering services team, EA was responsible for reviewing the designs by the other OEM manufacturers, developing the commissioning master plan and schedule, and coordinating the contractors. As the project went on, EA became more and more involved in the development tasks of the project. They created and changed PLC programs and helped develop new SCADA screens.
LACSD had developed new plant standards for their newer hardware and software, yet another driving force behind the project. They wanted the ECM programming and graphics to match these updated standards. Once EA’s project scope was expanded, engineers quickly began working with the PlantPAx, FactoryTalk, and Studio 5000 templates, eager to bring additional value and knowledge to the project.
