Clark Regional Wastewater District – Wastewater Lift Station
Project Description
Romtec Utilities designed and supplied a wastewater lift station for a new housing development in Vancouver, Washington. The system needed to handle medium flows of wastewater from the surrounding area, including multiple new residences. Romtec Utilities used Ebara 20 hp submersible pumps with solids-handling capabilities in a duplex configuration to meet the pumping requirements. All of the components used in this sewer pump station were selected to meet the design standards of the local water authority. This included an ultrasonic transducer for in-well level sensing with a conductive probe for redundancy. Romtec Utilities also provided a chemical feed odor control system for this lift station to prevent corrosive H2S gas from damaging the wet well, pipes, and other downstream infrastructure. Electrical controls were designed with a Micrologix PLC and connect to pumps and other in-well components through a disconnect stand. This allows personnel to perform maintenance and troubleshooting on pumps quickly and safely.

Why They Chose Romtec Utilities
Romtec Utilities was contacted to provide the design and supply of a wastewater lift station as a complete package for a new housing development in Vancouver, Washington. The location of the development required Romtec Utilities to adhere to the robust design standards of the Clark Regional Wastewater District (CRWWD) for new lift stations. Romtec Utilities has provided multiple pump stations for CRWWD and is experienced working with their lift station design standards. Like many housing development projects, the initial design and installation of this lift station was the responsibility of the developer. Hinton Development and their site engineer, SGA Engineering, worked directly with Romtec Utilities to complete the design of the lift station according to the site-specific requirements. The design was reviewed and approved by SGA Engineering and CRWWD. Rotschy, Inc., was the contractor for this project and completed the installation of the system. Once the rest of the site work was completed and the system was ready for start-up, Romtec Utilities sent a start-up technician to the job site to commission the system, test the system, and train operating personnel. Ownership of the lift station was then transferred to CRWWD.
