A residential boom town of employees from nearby natural gas mining facilities needed a large lift station to handle over 1.2 MGD of wastewater. Submersible Ebara sewage pumps in a triplex configuration were included for the new and future pumping rates resulting from residential growth. The lift station controls are located in a nearby control building. The UL listed control panel utilizes floats for primary and backup level controls, an autodialer for communications, and a permanent onsite generator for backup power.

A large book distribution center required the local municipal agency to install this package wastewater lift station. The force main was installed via a horizontally drilled hole to the exact elevation of the wet well connection. The submersible solids handling pumps are explosion proof to meet the hazardous area classifications for this lift station. A sheltered PLC control panel contains an intrinsically safe barrier to also meet the hazardous area requirements. The panel utilizes a pressure transducer and floats for primary and backup level-sensing controls.
