Founded in 1963 and headquartered in Tomah, Wisconsin, USEMCO Inc. has been an industry leader in engineering and manufacturing custom pump stations, water boosters, control systems, modular buildings, and steel fabrication solutions. All pumping stations are pre-assembled and factory-tested, requiring only electrical and piping connections. Over the years, we’ve developed three distinct brands — PumpMate, AquaPak, and Northland Tank & Fabrication — to cater to diverse industries, including but not limited to municipal water management, wastewater treatment, industrial facilities, and commercial applications.

PumpMate is our wastewater brand for pre-engineered, custom-built pumping stations designed for efficiency and dependability in municipal and industrial wastewater systems. AquaPak specializes in water booster systems that deliver precision and high performance for potable water applications in commercial and municipal settings. Northland Tank & Fabrication focuses on crafting high-quality tanks and steel structures, offering versatile solutions for fuel storage, process systems, and more. Together, our brands, extensive expertise, and innovative designs provide a comprehensive range of products and services designed to meet the unique needs of our customers. Make USEMCO your trusted partner for engineered solutions that perform reliably in even the most demanding environments.

Our diverse fabricating capabilities also include the production of underground and above-ground steel fuel storage tanks, ASME pressure vessels, process tanks, and major specialty subcontract fabricating.

Our custom design and manufacturing allow USEMCO to offer quality cost-efficient products that are engineered for the specific application. From job shop and custom fabricating work to pumping stations and control systems, USEMCO is here to work for you.

The USEMCO Difference

USEMCO is in total control over the entire manufacturing process. As a member of the Steel Tank Institute, USEMCO rolls, welds, fabricates, blasts and coats all of the steel for the pump stations and products we make.

Our customers benefit from industry first designs like our stairway entrances and factory shimming of the base for proper drainage to the sump.

Station bases are fabricated and the pumps, valves, and piping are installed to the base before the shell is attached. The painted shell and head is lowered as one unit onto the base and welded.

The processes that take place in-between the fabrication and shipping are as follows.

  • All welds are dye-checked for integrity. The steel is blasted in our booth to a near-white finish using an angular grit shot.

  • The product is then immediately transported to the staging area in-between the blast and paint booth for inspection and to have every weld hand striped coated to insure that the proper coating thickness is achieved on the welds.

  • The product then goes into the paint booth. The applicators use pneumatically powered lifts on each side of the booth to insure proper access for coating the pumping station uniformly and to specification.

  • Once the shell has past through the coating process it is then mated to the base assembly.

  • Piping penetrations that have to be made after the shell and base are welded together are die checked and then re-coated. Note the two different colors of coating. By applying the coatings in separate applications using different colors we insure proper coating thickness throughout the surface area by covering over the contrasting layer.

  • Stations are then tested to design conditions not just hydrostatically. This is done with every station except those that exceed our power and suction capabilities.

USEMCO’s design and manufacturing philosophy is reflected in the quality of the product, our state-of-the-art facilities, and our information technology infrastructure.

Our diverse capabilities of custom design and manufacturing enable USEMCO to offer quality cost-efficient products that are engineered for your specific application. From pumping stations and control systems to job shop and custom fabricating work. USEMCO is here to fulfill your needs.
