How To Extend The Life Of Your Wastewater Pumps

By Steve Craig, Fluid Components International (FCI)

Wastewater treatment plants use numerous pumps in a variety of types and sizes to move water through the process. Depending on plant configuration, they may pump influent, activated sludge, thickened or digested sludge, biosolids, scum, filtrate, effluent, or reuse water. Each matrix has specific characteristics that engineers consider when designing pumping systems.

These wastewater pumps are very expensive, typically costing more than $5,000 per pump. Emergency repairs often include overtime costs, which can add on hundreds of dollars depending on the size of the emergency. The loss of a pump is not only costly, but puts the facility at risk of violating regulations. Even though permit violation costs are often budgeted in, facilities would prefer to avoid such fines. Protecting pumps from damage saves money and protects the environment.
