A new school needed this package lift station to pump stored wastewater every 24 hours. The sump was oversized by design to hold in excess of 5,000 gallons of sewage that would be pumped out at specified medium pumping rate to a low-level shutoff float control. The submersible solids handling pumps in a duplex configuration are accessible by a crane installed on the top slab. An outdoor UL listed control panel is tied-in to an onsite generator for backup power and utilizes an autodialer for communications.

The expansion of a college campus required this stormwater pump station to handle medium flows of stormwater runoff. To meet the required pumping rate, 7.5 hp Ebara submersible centrifugal pumps were designed in a duplex configuration. This pumping system was designed with dual force mains and check valves integrated in the discharge piping to simplify the engineering for the system. Romtec Utilities provided the complete electrical engineering plans for the UL listed control panel. Floats for primary and backup liquid level-sensing were supplied to give the system added redundancy.
