The Stringfield at Granite Mountain site sits above much of the surrounding area, creating extreme elevation challenges for water delivery. Because of this, a basic water system using gravity alone would not work. Instead, a booster pump station and lift station system was needed to move water uphill and keep pressure consistent throughout the development.
Romtec Utilities partnered with LGI Homes to deliver a complete residential wastewater pump station for the Eldorado housing development in Kitsap County, Washington. Initially the scope only included Eldorado, but the system was expanded to include the adjacent development, Verbarendse.
This high flow wet/dry lift station replacement was installed “in the sand” of Main Beach with three dry pit pumps in a 26-feet-deep precast rectangular vault. Triplex split case pumps, sump pumps, an intake/exhaust fan, lights, valves, stairs, and a mezzanine were all provided in the package. The Allen Bradley PLC control panel, flow transmitter, and junction box are located in a control building. Sophisticated SCADA, 3 levels of redundancy, auxiliary power, and an HDPE wet well are all primary components of this package lift station.
To create new potable water, this lift station pumps clean stormwater from a collection/storage basin to a treatment facility. Duplex vertical turbine pumps move high flows of water very efficiently and use soft starters to reduce torque on the vertical shaft and provide additional pump diagnostics. Also included is an above-grade valve assembly on the top slab. The control panel utilizes an ultrasonic transducer for primary level controls and a pressure transducer for backup. The entire package lift station is located inside an owner-supplied control building.
Romtec Utilities supplied a wastewater lift station that will be owned and maintained by the Sacramento Regional County Sanitation District.
