The Arapahoe County Water/Wastewater Authority holds a unique client within its district: the Arapahoe County Detention Center.
The hassles of pump ragging lead a South Carolina Public Service District to change out problematic pumps for Flygt N3171 submersibles.
Sun City, AZ, has had the same wastewater treatment plant since the '70s, along with a new, expensive problem: non-dispersible waste.
Pump blockages and rags are a significant barrier to energy and operational efficiencies at pump stations, causing unscheduled shut downs, safety hazards for operators, costly equipment repairs and increased power usage due to a decrease in the pumps’ hydraulic performance. Scottish Water observed these negative effects caused by an influx of wipes and rags throughout a network of area pump stations. Engineers looked to a proven, powerful solution in the form of two JWC Environmental Channel Monster® grinders at one of their most problematic sites.
Keeping up with both the water needs and sewage disposal of the Santa Margarita Water District has come with significant challenges, particularly due to both the increase in influent and change in the makeup and durability of the sewage running through the district’s reclaimed-water facility.
The Independence Hill Conservancy District's Taney Lift Station was having continuous problems with wipes, swiffers, and plastics deposited in the incoming lines, which then broke loose in storms and overwhelmed the old non-clog pumps.
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.
