Equipment Chosen For Efficiency And Reliability In Lift Station Overhaul

The 5.8 million gallon per day (mgd) Fairwood Lift Station, one of 76 major stations in the Hot Springs system, experienced frequent overflows. Particularly, the station struggled during heavy rainfall events or when pumps clogged because of increasingly popular "disposable" products such as duster heads, cleaning cloths, and disinfecting wipes, which can build up on the leading edge of the pump impeller and become entangled, reducing the efficiency of the pump or even causing a complete stoppage.

A new Xylem Flygt MultiSmart station controller was installed to provide both real-time control and protection along with historical and communications options. The installed MAS 711 pump monitoring system, which records pump starts and stops; pump vibration; station power quality and energy usage; and pump bearing and seal temperatures, will calculate and record the daily inflow and outflow of the station in gallons per day.
