McMillan Water
Treatment, Inc.

McMillan Water Treatment has been providing services since 1966.

The company was founded by David G McMillan. The company quickly evolved into a highly regarded name within the industrial Water Treatment Service industry. Early on, McMillan realized the need and importance of providing “service” on equipment that went beyond the common water treater’s role. McMillan continues to take pride in their service, which separates them from most Water Treatment companies. Currently, David J McMillan continues to carry on his father’s legacy as owner of McMillan Water Treatment, Inc.

As McMillan continues to be an industry leader, with a solid reputation and commitment to honest and reliable service, McMillan provides services in California, Nevada, and Arizona. Our Tri-state locations service hundreds of locations monthly that include various types of systems and industries. For example, HVAC/refrigeration, commercial, industrial, manufacturing and more.

The employees of McMillan Water Treatment Inc. are background checked and extensively trained to be knowledgeable of the equipment being serviced, ethical and proper Water Treatment practices, including chemical applications and safety. Our long tenured management team is highly respected within our industry, and is committed to providing excellent customer service.

We take pride in knowing that our contribution in water conservation, reduced energy costs, and extending equipment life expectancy, all result in reduced operation expenses for our customers.
