The Wet Well Mounted Pump Station (WWMPS) by Smith & Loveless offers many distinct advantages over submersibles, including significant savings in operating costs as demonstrated below.
Actual 9-Year Cost Comparison
The progressive Unified Government of Wyandotte County and Kansas City, Kan., operates numerous wastewater pump stations in its sewage network, including 30 duplex Smith & Loveless vacuum primed WWMPS and 21 duplex submersible stations. For each station (all with flow conditions of less than 1,000 GPM per pump and 50,000 GPD), the Unified Government keeps detailed records of all repair and maintenance work orders and costs.
As Figure 1 demonstrates at right, a nine-year data compilation reveals that the average annual repair and maintenance expenditure per pump station was 52% less for S&L stations compared to submersible stations (2002-2011). This staggering differential translates to savings of nearly $2,500 per station per year.
The complete study measures and compares labor hours and costs, outside contractor expense, material costs and total expenditure. In all, the results overwhelmingly favor the S&L Wet Well Mounted Pump Station approach with the thousands of dollars saved annually in maintenance and repairs.
