Whether you’ve worked with Southern Utilities for decades or just recently, we want you to know that our team is here to make the transition smooth, seamless, and stress-free.

Honoring the Southern Utilities Legacy

Founded in 1932 by Stephen Ambrose Gorman, Southern Utilities built its reputation on engineering expertise, reliable equipment, and strong customer relationships. From its early days in Washington, DC, to serving Maryland and beyond, the company was known for being “More Than A Pump House.”

We at Cummins-Wagner share these same values and are committed to carrying forward Southern Utilities’ legacy with the same dedication, technical knowledge, and personal touch.

About Cummins-Wagner

Founded in 1960 by “Charlie” Cummins and “Chub” Wagner, Cummins-Wagner has grown from a regional distributor into a 100% employee-owned company serving Maryland, Virginia, Washington DC, Delaware, West Virginia, Pennsylvania, New York, and New England.

Over the decades, we have expanded through strategic acquisitions—including Siewert Equipment, F.R. Mahony, and Thermoflo—and today we are a trusted source for:

• Pumps
• Air compressors
• Cooling Towers
• Plumbing
• Boilers
• Heat transfer equipment
• Packaged systems and engineered solutions

Because we are employee-owned, every member of our team is personally invested in your success. We don’t just sell equipment—we engineer solutions, install systems, provide maintenance, and offer full repair services for both the products we sell and many we don’t.

How We Can Support Former Southern Utilities Customers

As your new partner, Cummins-Wagner offers:

• Application-specific equipment recommendations
• Turnkey installation and startup
• Preventative maintenance programs
• 24/7 emergency service
• Access to industry-leading brands and parts

Our mission is simple: to provide efficient, effective solutions to mechanical equipment applications—and to support our customers long after the initial sale.
