Founded in 1928, Mechanical Equipment Company (MECO) has been a pioneer in advanced water purification technology for nearly a century. From patenting the world’s most efficient vapor compression process for seawater desalination in 1939 to powering today’s critical industries, MECO’s legacy is built on innovation, reliability, and a relentless commitment to quality.
Today, MECO is a proud member of the Grundfos family, following its acquisition by Grundfos in 2021. This partnership strengthened MECO’s global reach and investment in sustainable, high-performance water solutions. In 2022, MECO expanded further with the acquisition of Water Works, enhancing our capabilities to deliver fully integrated ultrapure water solutions for the pharmaceutical, biotechnology, healthcare, and industrial sectors. Together, MECO and Water Works empower customers’ breakthroughs with a complete portfolio of purified water, WFI (Water for Injection), pure steam, and laboratory water systems — backed by decades of expertise and service excellence.
Headquartered in Mandeville, Louisiana, MECO operates a state-of-the-art manufacturing facility that represents the best in energy-efficient design, precision engineering, and operational excellence. Our commitment to customer success is reflected in a proud track record: over 75% of MECO customers are repeat customers, many of whom have partnered with us for over 20 years.
