Our History

Henry Mayer, along with his brother August, founded Mayer Brothers in 1959. His daughter, Nancy, continues its operation today, and Henry wouldn't have it any other way.

Henry's father, August Mayer, was a general contractor in nearby Relay, Maryland in the early 1900's. He saw a need for a precast operation in the area. Precast concrete was a new concept, and several customers started asking for small pipe and valve vaults - products that are still made today.

Although some of our product lines are over 50 years old, Mayer Brothers has progressed and now makes some of the most advanced on-site wastewater treatment plants available. We are viewed as leaders in grease interceptor design and manufacture, and we offer state of the art oil-water separators.
