Surge Protection for Lift Stations OVERVIEW Today’s increased reliance on very sensitive electronics makes surge protection an important topic for Water and Wastewater Management. The Insurance Institute for Business & Home Safety study found that $26 billion dollars was lost due to non-lightning power surges. In addition, there are about 25 million lightning strikes in the US each year that cause between $650M to $1B in losses according to the Insurance Information Institute, State Farm©. This article discusses the various aspects of Water and Wastewater Treatment (WWT) systems to help you develop a comprehensive surge mitigation strategy for your equipment. Each section will conclude with a Surge Protective Device (SPD) Protection Point which identifies where and what SPD to use. Lift Station | Pump Panel Lift Station The lift station, also called the pump station, is a critical element of the wastewater infrastructure. Among the variety of configurations of lift stations they usually house pumps, control panels, backup generators in case of emergencies. Lift stations require reliability for constant use for households, businesses, and industries that each contribute wastewater. SPD Protection Point - Pump Station Per the NEC 2020, Article 708.2, defines a Critical Operations Power Systems as one that affects business continuity. A UL listed Surge Protective Device must be installed to be compliant with the NEC.
