Assembling of the Concrete Wet Well in a Large Hole

Commercial Development | Newark, DE | 60 GPM - 16' TDH

jweddell50gpm - 100gpm, Apartment Complexes, Eastern, Wastewater

A commercial development in Delaware required this wastewater lift station to handle low flows of sewage from a new fast food restaurant and retail stores. Tsurumi cutter pumps in a duplex configuration macerate solids any in the wastewater to pass through the force main diameter. This lift station pumps a short distance with low head to a nearby gravity collection system that flows to treatment. A UL listed control panel was supplied for complete electrical controls with Nolta Niva floats for in-well liquid level-sensing.

The Union Pacific Depot in Cheyenne, Wyoming needed two new sewer lift stations to replace its existing sewer collection system. Each lift station included three precast concrete vault structures, a wet well, valve vault, and metering vault. Both systems use 2 hp Ebara Vortex® sewage pumps in duplex configurations that are explosions proof rated for Class I, Division I locations. The valve assemblies comprise Val-Matic Cam-Centric® plug valves and Swing-Flex® check valves with pressure gauges. Endress and Hauser PROline® electromagnetic flow meters measure the sewage flows for both lift stations. These in-ground valve and meter assemblies were fitted with heat tracing to provide reliable frost protection with Raychem and Digitrace components.

City of Shafter in California

A suburb of the City of Shafter required a lift station package to repair and rehabilitate an existing wastewater sump. Duplex submersible centrifugal pumps and discharge pipe mounting brackets were fitted to a concrete slab poured in the bottom of the existing manhole. The Romtec Utilities package included the proper components to operate in this 26-foot-deep sump. An outdoor MultiSmart control panel utilizes conductive probes for primary and backup level controls and an autodialer for communications. This retrofit package saved about 60% the cost of a new lift station.

The City of Brawley needed this packaged lift station to handle high flows of wastewater at its municipal treatment plant. 12 HP submersible pumps in a duplex configuration were used to meet the high flow pumping needs and a conductive probe was used for liquid level-sensing. The in-ground valve assembly and meter assembly were each located in separate vault structures for a cost effective design and easy access. An outdoor, UL listed control panel was protected from weather and sunlight by a six-post shelter, which also covers the sump entry hatch and electric disconnect panel.

The City of Camas | Camas, WA | 126 GPM - 206' TDH

jweddell100gpm - 300gpm, Municipal Collection, Odor Control, Pacific, Residential Development, Sewer System Expansion, Urban Growth, Wastewater

In order to expand the municipal sewer system, this lift station was configured to pump to an existing gravity line flowing to treatment. A 24-foot-deep by 10-foot-diameter wet well collects the sewage flows. The wastewater is pumped at 120 gpm 10,000 lineal feet of 10” force main against 206’ TDH with 23 hp high head submersible solids handling pumps. A sheltered control panel utilizes an intrinsically safe barrier for in-well electrical, such as the pressure transducer and conductive probe for primary and backup level controls.
