The Marathon Petroleum Refinery in Robinson, IL needed this new industrial process water pump station to handle its medium flows of highly acidic water combined with standard wastewater. A precast concrete sump included an interior Tnemec coating to withstand the water chemistry from a refinery testing lab. 11 hp Goulds grinder pumps were designed in a duplex configuration and included a factory epoxy coating to withstand the water chemistry. The pump station piping was designed with stainless steel components, and corrosion resistant floats were included as the liquid level sensing devices.

Plantation Pipe Line Received a Stormwater Pump Station

Plantation Pipe Line|Polk County, GA|175 GPM - 90' TDH

jweddell100gpm - 300gpm, Eastern, Oil & Gas, Stormwater, Stormwater Runoff

This package stormwater lift station was configured to meet the medium runoff flow of this industrial property. One submersible centrifugal pump makes this a simplex station with an in-well check valve. The single pump handles high head conditions caused by 9,000 feet of 4” force main. Additional system valves are located in a below grade valve vault. An outdoor control panel includes floats for liquid level-sensing and a basic alarm for communication. A Thern crane was included with this station to raise and lower the pump.

jweddell1,000gpm - 5,000gpm, Central, Industrial, Industrial Water, Oil & Gas, Wastewater

A liquid hydrogen plant required this large 20’ deep lift station to handle super-high flows of industrial wastewater. In order to provide redundancy and expanded pumping capabilities, triplex submersible centrifugal pumps were specified in the 8’ diameter sump. A large custom valve vault holds the complete 8” valve configurations with triplex discharge piping and force main headers. Two below grade junction boxes hold electrical disconnects to comply with the classified space. An outdoor UL listed control panel uses float controls for primary and backup liquid level-sensing.

Dow Chemical Company

jweddell50gpm - 100gpm, Central, Oil & Gas, Wastewater

This package wastewater lift station replacement was delivered largely preassembled for quick and simple installation by the customer. This procedure provided an expertly designed lift station that would uphold the privacy values of the facility. The fiberglass wet well arrived with mounting hardware, discharge piping, and the valve assembly preinstalled. Only the duplex solids handling pumps needed to be lowered after installation of the sump. An outdoor UL listed control panel was designed with float controls for liquid level-sensing and included an autodialer for communications.

Tesoro Oil and Water Separator Pump

Tesoro Corporation|Port Angeles, WA|400 GPM - 30' TDH

jweddell300gpm - 500gpm, Industrial, Industrial Water, Oil & Gas, Oil/Water Separators, Pacific, Stormwater, Stormwater Runoff

A remote Tesoro Corporation industrial site needed this stormwater pump station to handle water discharged from an oil/water separator which processes on-site runoff. Submersible centrifugal pumps were used in a duplex configuration in this shallow wet well. The 7.5 hp Ebara explosion-proof pumps were sized to meet low flow, medium head conditions for stormwater. Check valves and plug valves were integrated into the discharge piping in the well for a simple and cost-effective design. The precast concrete wet well and the access hatch are both pedestrian rated.
