A Rewardinq Restoration: Submersible Pump Replacement at IN Lift Station Cuts Repair Costs, Improves Performance

摘要

The population of Fishers, Ind., a suburb of Indianapolis lying northeast of the city, is rapidly growing with an increase of about 110 percent since 2000. In 2002, the town's wastewater treatment plant expanded to its current capacity of 8 million gallons per day (mgd), although it normally sees flows on an average of 6.2 mgd. The Cedar Cove lift station, one of 22 in the town, was in major need of renovations by 2011. Constructed in the early 1990s, the duplex station serves an apartment complex and residential area of around 350 units. It was exhibiting a number of problems, including outdated controls, wet-well corrosion and failed valving. But perhaps the biggest problem was the two unreliable submersible pumps that were frequently failing due to clogging and seal damage.
