Haynes Equipment Company started business in 1961 as a company representing several manufacturers in the Water and Wastewater Industry in Missouri and Kansas.  In 1971 we opened an office in Oklahoma City followed by our Tulsa office in 1999.

The Company was built on the premise of selling quality products at competitive prices and being able to service and maintain all of the equipment we have sold.  The Company’s formula of success has never been compromised and as a result, the Company is still growing.  In 2018 we celebrate our most recent expansion, opening Haynes Pump and Process based in Little Rock, Arkansas.


We equip and service the water and wastewater treatment industry to provide clean water that sustains life.


Our Staff consists of professionals in the Civil, Environmental, Mechanical, and Chemical engineering disciplines, highly qualified project managers, field service technicians and customer service personnel.
