Frost goes deeper in Marathon County than it does in the southern half of the state, and a plumbing system in Wausau has to account for that in water services, storm lines, and any pipe that runs near an exterior wall or loading dock. Southport Mechanical designs and installs commercial plumbing for plants, clinics, schools, and apartment buildings across Wisconsin, with pipe assemblies prefabricated in our own facility to shorten time on site.

Reasons to Call a Commercial Plumbing Contractor

Plumbing problems in a commercial building tend to grow quietly until they shut something down. These are the situations where an assessment now saves a larger repair later.

  • Pipes that freeze every winter in the same wall, dock, or mechanical room need rerouting, insulation, or heat, and patching them again only resets the clock.
  • Slow floor and trench drains in food processing or production areas often point to buildup or a sag in the line beneath the slab.
  • A failed backflow test has to be corrected before the device can be returned to service and recertified.
  • Plant expansions frequently need new process water, compressed air, or gas piping that the existing system was never sized to deliver.
  • Low pressure on upper floors in older buildings can mean corroded supply piping or a booster system that has reached the end of its life.

Commercial Plumbing Design and Installation

Layout begins with the fixture schedule, any process loads, and the state plumbing code that governs commercial work in Wisconsin. Our engineers route water, drainage, venting and gas around the structure and coordinate it with the HVAC and fire sprinkler layouts, so the trades are not competing for the same space overhead. In cold-climate work, that layout also keeps vulnerable piping inside heated space wherever possible and protects what cannot be moved.

Industry shapes plumbing scope around Wausau. Food and dairy processors need sanitary drainage that holds up to washdown, paper and wood products plants run process water and compressed air through the facility, and clinics and senior living buildings need domestic hot water held at safe temperatures around the clock. We design and install:

  • Potable water, drain and roof storm piping sized for the full building.
  • Natural gas distribution to boilers, unit heaters, kitchens and process burners, coordinated with our commercial HVAC team when the gas load feeds heating equipment.
  • Compressed air distribution for pneumatic tools and automated equipment on the plant floor.
  • Industrial process piping built to a facility’s specific requirements.
  • Deionized water lines for labs and manufacturing that cannot tolerate dissolved minerals.
  • Backflow assemblies that keep process water and chemicals out of the municipal system.

With sewer cameras and locating gear, our crews pinpoint breaks, sags and blockages before anyone opens a slab.

Prefabrication shortens field schedules. Risers, headers and underground runs are assembled at our shop, tagged by location and trucked to the site. For the Summer Ridge Apartments, every piece of underground sanitary pipe was shop-built ahead of time.

New Construction

We plumb new buildings through design-build or by installing to an engineer’s drawings. Our crews have handled plumbing at a large scale, including more than 180 residential buildings at the Springs of Kenosha development.

Repiping and Upgrades

Aging galvanized, copper, and cast iron systems can be swapped out zone by zone so tenants and production keep running. We schedule shutdowns ahead of time and restore water to occupied areas quickly.

Inspection and Maintenance

Routine inspections of water heaters, backflow assemblies, drains, and gas piping help facility managers find problems while they are still small.

Thank you for sending Andrew Wenk to test our furnace. He could answer our questions clearly and tested all the important components and measured various pressures, temperatures, speeds, and other technical factors. He gave us 3 estimates for replacing parts that are needed due to age of the furnace. Andrew was pleasant and respectful to us.

Southport’s Technician , Phil Lloyd, is a true asset to his organization! My wife, Karyn and I have had many contractors come through our house over the years and I would put Southport at the very top of our service partners. They are knowledgeable, reasonable, and most importantly trustworthy. Phil Lloyd took the time to share, in layman’s terms, the root cause of our problem and a remedy that would bring our system back up and running; peace of mind to our family. I would highly recommend Southport, and would give Phil Lloyd a 10 out of 10 related to Service, quality, and most important trust. Southport is fair on cost,I plan on partnering with Southport for many years to come. Jim Sheehan
