jweddell100gpm - 300gpm, Data Center Cooling Waste, Data Centers, Municipal Collection, Pacific, Sewer System Expansion, Wastewater

This large commercial facility needed identical lift stations to manage wastewater in the form of sanitary sewer and discharge water from the cooling processes. This was the second of four Romtec Utilities lift stations supplied to Microsoft’s 70-acre data center. Aircraft rated hatches are included for each lift station to handle heavy forklift traffic. Outside the sump, two valve cans provide access to the below-grade check valves. An outdoor UL listed control panel utilizes an intrinsically safe barrier for in-well electrical controls and utilizes float controls for liquid level-sensing.

To handle a combination of sewer and cooling process wastewater, this commercial facility purchased four identical Romtec Utilities package lift stations. This was the third of four lift stations supplied to Microsoft’s 70-acre data center. Aircraft rated hatches are included for each lift station to handle heavy forklift traffic. Valve cans provide easy access to the below grade check valves with much less material costs than a valve vault. An outdoor UL listed control panel includes floats for level controls and an intrinsically safe barrier for in-well electrical controls.

The City of Arcata | Arcata, CA | 2,947 GPM - 34.2' TDH

jweddell1,000gpm - 5,000gpm, Municipal Collection, Municipal Lift Station Replacement, Pacific, Wastewater

This “turnkey” replacement lift station was designed, supplied, and installed to meet super-high sewage flow with infiltration and inflow requirements of a municipal wastewater lift station. Submersible solids-handling pumps in a triplex configuration were installed. The below-grade valve assembly includes plug valves, check valves, ball valves, a pumping port, and a pigging port. The UL listed control panel has an ultrasonic transducer for primary liquid level sensing, redundant float controls, and an autodialer alarm. VFDs were also included in the lift station controls.

jweddell50gpm - 100gpm, Municipal Collection, Municipal Lift Station Replacement, Pacific, Replacements & Retrofits, Wastewater

Santa Barbara County needed this package lift station to replace an existing system serving a residential area next to Goleta Beach. Ebara submersible sewage pumps were engineered in a duplex configuration to alternate starts and create redundancy in the system. Liquid level-sensing also includes redundancy by using Dwyer floats as the primary control device and a Multitrode probe for high-level backup. A UL listed control panel uses a NEMA 4X stainless steel enclosure to be safely located outside of the existing control building.

The City of the Dalles | The Dalles, OR | 38 GPM - 28.2' TDH

jweddell5gpm - 50gpm, Municipal Collection, Pacific, Replacements & Retrofits, Wastewater

The City of the Dalles required this replacement package lift station to meet medium flows of municipal wastewater. This lift station included submersible centrifugal pumps in a duplex configuration with the ability to handle some suspended solids. The control panel for this lift station includes SCADA software to interact with a remote telemetry unit (RTU). These two systems provide communications from the pressure transducer and conductive probe level sensing devices. They also communicate calculated flow rates and any voltage variances in from the power supply.
