smith and loveless wet well mounted pump stations cost analysis versus submersible proven savings wyandotte county kansas
 
For more than 12 years (2002-2014), the progressive Unified Government of Wyandotte County and Kansas City, Kan. has kept detailed records of all repair and maintenance work orders for the 53 duplex wastewater pump stations in its sewerage network. Of these stations (all with flow conditions of less than 1,000 GPM per pump and 50,000 GPD), 32 are Smith & Loveless vacuum primed Wet Well Mounted Pump Stations (WWMPS) and 21 are submersible pump stations. This study measures and compares labor hours and costs, outside contractor expense, parts costs and total expenditures for these stations over the 12-year period. See table at right for the full data on all 53 stations, including actual pumping conditions and all accumulated repair and maintenance costs per pump station.
 
Cost Comparison Results
The results overwhelmingly favor the S&L Wet Well Mounted Pump Station approach with nearly 56% in total cost savings, an average of more than $2,700 per pump station per year (nearly $400,000 saved by the city over a 12-year period).
