The Horn Rapids Triangle lift station was built to serve the Pacific Northwest National Laboratories project operated by Battelle for the US Department of Energy. RC Worst & Co. provided the project engineer a design for an Automated Flow Systems packaged lift station which includes a 8’ x 20’ wet well and 6’ x 11’ valve vault. The design features triplex pumps to allow interim operation with two pumps while the flows are limited early in the project yet allow full capacity operation by simply adding a pump as the project matures. The fabricated schedule 10 stainless steel discharge manifold leaves the 4” pumps, increases to 6”, and finally leaves the lift station with 8”. While the lift station required an extensive excavation due to the granular soils the contractor was still able complete the installation in three days.

Not unlike many municipalities, the City of Lewiston, Idaho had expanded and needed to develop an area that required a sewage lift station. While the City designer knew he needed to specify this lift station, he also had a vision of developing a standard that would be a future template expediting design and operation. After working with RC Worst & Co. for several months, an Automated Flow Systems package was developed that would accommodate all the features that he was looking for. The station itself was nearly a stock AFS design with a few extras included in the controls. The Hydromatic Novus 4000 controller is housed in a freestanding stainless steel enclosure, senses the sewage levels using a Blue Ribbon Birdcage submersible pressure transducer, and includes an Omnisite XR50 cellular lift station monitoring system. From delivery to backfill, this AFS Lift Station took only a few hours to install.
