A large neighborhood received these two lift stations that were designed to handle medium sewage flow requirements. The submersible solids-handling pumps in duplex configurations were specified to handle influent from three inlet lines from different sections of the neighborhood. The below-grade valve assemblies hold the system operation valves, bypass pumping ports, and shut-off valves. The outdoor UL listed control panels utilize pressure transducers and redundant float controls for liquid level-sensing; basic alarms were included for communications.

A liquid hydrogen plant required this large 20’ deep lift station to handle super-high flows of industrial wastewater. In order to provide redundancy and expanded pumping capabilities, triplex submersible centrifugal pumps were specified in the 8’ diameter sump. A large custom valve vault holds the complete 8” valve configurations with triplex discharge piping and force main headers. Two below grade junction boxes hold electrical disconnects to comply with the classified space. An outdoor UL listed control panel uses float controls for primary and backup liquid level-sensing.

This industrial pumping system was designed to handle medium flows of process wastewater created from cleaning cycles at the Merck Animal Health facility. The wastewater was specified with highly variable pH conditions, so the pumping system was designed with a double-wall fiberglass sump with leak detection. All of the submersible components in the well were constructed of stainless steel, including the Tsurumi duplex submersible pumps. The pumping system electrical controls comprised a UL listed panel with SCADA integration.

This industrial power plant needed a package lift station to meet the requirements for municipal wastewater. The 23-foot-deep sump holds duplex Goulds submersible sewage pumps specified to meet the 50 gpm maximum flow requirements. A precast concrete valve vault contains the system valves and a force main junction. Both the below-grade wet well and valve vault are pedestrian rated. Liquid level-sensing controls are a pressure transducer and floats for backup. The outdoor control panel includes a receptacle for an owner supplied onsite generator.

This package wastewater lift station replacement was delivered largely preassembled for quick and simple installation by the customer. This procedure provided an expertly designed lift station that would uphold the privacy values of the facility. The fiberglass wet well arrived with mounting hardware, discharge piping, and the valve assembly preinstalled. Only the duplex solids handling pumps needed to be lowered after installation of the sump. An outdoor UL listed control panel was designed with float controls for liquid level-sensing and included an autodialer for communications.
