As part of global critical infrastructure, water and wastewater facilities must operate continuously. Unplanned downtime not only reduces the capacity to treat contaminated water but risks cross contamination and reservoir overflows, which can lead to detrimental environmental effects. Fundamental water and wastewater plant processes, including filtration, extraction, and injection, rely on critical motor operation, making asset protection and reliable power nonnegotiable. Implementing SEL solutions built with the industry’s most rugged and reliable protection, control, and communications devices provides the operational stability that your customers—from individuals to global industries—need and expect. From retrofits to complete power management systems, our solutions improve your water and wastewater facility uptime and resiliency.
