City of Junction City – Replacement Wastewater Lift Station
Project Description
Romtec Utilities designed and supplied a wastewater lift station and control building to replace an existing municipal sewer system. The new lift station was designed with Flygt 18 hp pumps arranged in a triplex pumping configuration to handle high flows of wastewater from the surrounding area. Pumps are operated with a variable frequency drive, or VFD, to meet the varying flow demands the system encounters. The pumps and other in-well electrical components connect to the control panel through a disconnect panel using Meltric plugs to allow for easy pump station maintenance and inspections. Electrical controls, chemical feed odor controls, and an emergency generator were also supplied with the pump station and integrated into the design of the control building. This required the building to include a robust HVAC system to provide adequate ventilation and regulate the temperatures inside the building for the sensitive electrical controls. Remote monitoring and operation for this pump station was made possible through the implementation of Flygt’s proprietary FMC -400 controller connected to the city’s existing SCADA network.

Why They Chose Romtec Utilities
Romtec Utilities was contacted to provide the design and supply of a wastewater lift station for the City of Junction City in 2007. This system was needed to replace an existing sewer pump station in order to meet growing flow demands from the surrounding area and include modern features. This included connecting the system to the SCADA network and a chemical feed odor control system. Additionally, the wastewater for this lift station is sourced from a variety of buildings in the surrounding area, including a high school and several apartment complexes. One significant benefit Romtec Utilities brought to this project was our ability to design and supply the control building for the pump site. The building was designed alongside the pump station and integrates all of the necessary controls and auxiliary systems into the space. This required comprehensive knowledge of these systems and local building ordinances. Romtec Utilities worked closely alongside the Junction City Public Works Department to design the lift station and control building to their standards. Site-specific data and pumping requirements were supplied by Weber Elliet Engineers. Once the system design was approved, Romtec Utilities supplied the lift station and control building as a single package and provided an installation advisor onsite during the construction of the system. Romtec Utilities also provided start-up & testing services on the lift station and trained the public works department on the operation of the system and controls.
