Demonstrates an energy-efficient control method of lift station system operation that utilizes hydraulic modeling results generated from site-specific conditions to optimize pumping units and reduce simultaneous running cycles. Using the information obtained through a pilot study, the researchers developed a set of guidelines that detail how lift stations operational control can be optimized using advanced hydraulic modeling and new generation SCADA systems. The findings of this study can help wastewater utilities to reduce greenhouse gas emissions; reduce facility operating costs through designing capacity on optimized system operations, power savings, fewer service calls, and increased service life of assets.
