Our story dates back as far as 1975...

…when Environmental Dynamics International (EDI) was founded by Charles E. Tharp, a Columbia, Missouri-based company that quickly became a global competitor in biological wastewater treatment and advanced diffused aeration systems for municipal and industrial clients.

In 1999, EDI's Parts Division, Diffuser Express was launched

For customers that need direct delivery of aeration parts without any engineering, design, or installation services; EDI offers express delivery of diffusers, membranes, and specialty diffuser items through ‘DiffuserExpress’ (DX). Customers can find compatible parts for all brands whenever they need and experience worry-free aeration in their new and existing water and wastewater treatment applications. DX offers high-quality equipment for specific applications made and continuously improved with EDI’s aeration expertise, application knowledge, and in-house research and development.

The origin of today's SiteWorks Installation & Service team dates back to 2008

EDI established the contract services installation division in 2008 that currently operates as SiteWorks™. Experienced SiteWorks™ field service professionals are experts at installation and maintenance of aeration systems. SiteWorks provides system operators a source for fast, reliable installation and maintenance. Across North America, you can have SiteWorks install your brand-new aeration system, as well as upgrade and maintain your age-old existing system from another brand, and anything in between.

In 2020, EDI joined the Axius Water Platform.

With the acquisition of EDI by Axius Water and with close cooperation with Nexom, EDI continues to offer “aeration for life” through its engineered aeration technologies, and the combination of the two comapnies instantly creates a globally-competitive nutrient management leader offering an ever-broadening range of category-leading technologies. Axius Water, as it is now known, was created to address United Nations Sustainable Development Goal #6 by addressing the global wastewater nutrient crisis.

Innovation Continues...

As one of the largest Aeration System suppliers in the USA and a major global vendor, EDI continues to bring new aeration solutions to the market. In 2022, EDI’s premium FlexAir product line was relaunched as FlexAIR PRO™ and a FlexAIR BASIC™ line was introduced that conforms to the most common aeration specification that call for solvent welded 9-inch disc diffusers with a quality, American-made product.
