Macaulay Controls Company was founded in 1965 when Richard Macaulay first began representing a control valve product line. From this humble start, we have evolved from valves and controls into a true representative firm selling a full line of equipment and instrumentation critical for water and wastewater applications.

Over the years, we have worked hard to expand product lines, implement the latest industry technology, improve the quality of our services, and develop strong customer relationships. Through field demonstrations, application analysis, and design assistance, we are pleased to work with engineers and end users on these products and offer a complete solution to their needs.

Today the company is owned and operated by Kari Macaulay Hollway, Richard’s daughter, who started with the company in 1980. We are proud to still be a privately held, family owned organization with second generation leadership at the helm. Our team’s dedication to customer satisfaction since the beginning has driven us to be a leading manufacturers representative in the highly competitive water and wastewater industry.
