Northshore Utility District – Wet-Dry Lift Station for Residential Development
Project Description
Romtec Utilities designed and manufactured a wastewater lift station for a residential development in Kirkland, Washington. This lift station was designed with a wet-dry pumping configuration with a wet well and an adjacent dry well. Two 17hp Flygt pumps were installed inside the dry well to meet the medium flow and high head pumping requirements. Personnel can easily enter the dry well for maintenance using a ladder with an air exchange system and emergency system shut-offs in the well for safety. Electrical controls and the emergency generator are located under a steel 4-post control shelter with a cmu block wall and fencing surrounding it. Wastewater levels are detected in the wet well using a pressure transducer and an array of mechanical floats for backup level sensing.

Why They Chose Romtec Utilities
Romtec Utilities was contacted to provide the design and supply of a sewer lift station to connect 12 newly constructed homes in the Seattle metropolitan area. Our scope on this project included the structural and mechanical systems. Romtec Utilities designed the lift station in a wet-dry pumping configuration to meet the standards of Northshore Utility District (NUD), the water authority, while working with Blue Line Group, the engineer. Buchan Homes was the developer of the new homes and requested the lift station have a low-profile design so residents would not be bothered by loud generators and unsightly equipment. The system was designed according to these specifications and was approved by NUD. Steve Ruhnke Construction completed the installation of the lift station. Romtec Utilities provided a construction advisor to the job site to answer any questions regarding the system. A Romtec Utilities field technician travelled to Kirkland to commission the system and provide testing & training services for the operators at NUD.
