STRONGER TOGETHER

We are committed to excellence in meeting the current moment’s environmental, social, and governance (ESG) needs.

EDI’s impact on the world 

…is much bigger than the aeration systems we supply or numbers that show up on financial statements. As a part of the Axius Water platform, we are part of a global team that is meeting some of the critical challenges of our time with energy, determination, and creativity, at a growing scale that is making a real difference.  Stronger Together, Axius Water’s 2021 Sustainability Report, shares the depth and breadth of how our platform is collectively addressing these challenges. You can download the report in full, but make sure to scroll down to discover how EDI specifically is contributing. 

From the Axius Water CEO 

“Like many other companies, Axius experienced unprecedented challenges resulting from the ongoing pandemic in 2021. It was gratifying to see our teams adapt to the new normal as they prioritized doing business safely while continuing to serve customers. Our business resilience was tested — and proven — as we confronted and resolved supply chain disruptions and shortages of key raw materials. Through it all, our people worked as a team to overcome obstacles and remain focused on our mission to achieve clean water globally by bringing people together to drive out nutrient pollution. I am so proud of the Axius team for excelling, collaborating, and adapting. They proved that, indeed, we are stronger together.”

Restoring the Chesapeake Bay Watershed

A once-vital ecosystem is bouncing back thanks in small part to our collective action.

Restoring the Chesapeake Bay Watershed 

Encompassing nearly 4,500 square miles, the massive Chesapeake Bay is the birthplace of much of the shrimp, oysters, and other aquatic life in the northern Atlantic Ocean. However, the rivers that flow into the Bay are laden with pollutants from the enormous 64,000 square mile Chesapeake Bay watershed, which extends from Delaware, the District of Columbia, and Maryland into Pennsylvania, Virginia, West Virginia, and even New York. Nutrient pollutants (i.e., nitrogen, phosphorous, and ammonia), including fertilizer from farms as far away as New York State, collect in the Bay, where they create hypoxic or dead zones that kill fish and harm other aquatic life. 

EDI has provided aeration products to more than 450 wastewater treatment plants in the Chesapeake Bay watershed, serving well over 15 million people. One of its largest customers is the Washington Suburban Sanitary Commission (WSSC), which EOSi also serves. Established in 1918, WSSC is one of the largest water and wastewater utilities in the nation, serving 1.9 million residents over an area of nearly 1,000 square miles in Prince George’s and Montgomery counties. Recently, EDI replaced outdated equipment in the WSSC’s Piscataway Water Resource Recovery Plant, which could no longer achieve regulatory limits…

Why is the Chesapeake Bay so important?

The Chesapeake Bay is the largest of more than 100 estuaries in the United States. As such a large estuary, the Bay impacts the health and safety of 18 million people who live in the Chesapeake Bay watershed as well as thousands of species of animals and plants. The Bay also supports the seafood, recreation, and tourism industries, making it an important economic resource.

ESG Impact Summaries

Our contributions toward building a more environmentally-friendly, socially-equitable, and responsibly-governed world.

Environmental Performance 

Water Quality Management  

By helping its customers reduce pollution and improve water quality, Axius Water contributes to measurable progress toward SDG 6: Clean Water and Sanitation.  EDI and Nexom design, manufacture, install, and service simple and sustainable technologies that enable small and remote communities to manage local waterway impacts with limited resources effectively. 

“I come to work excited every day, knowing that I am making a difference in the world by helping our clients achieve cleaner water. I’m grateful that my education and experience enable me to help people and our planet.” Tanner Devlin, PhD EDI Regional Sales Manager

Regulatory Compliance 

We provide services and products our clients use to monitor and manage the quality of their wastewater discharge to comply with regulatory quality standards.  EDI and Nexom sales and applications teams monitor changes to North American effluent discharge regulations at the federal, state, and provincial levels and develop strategies to help customers achieve compliance. 

Climate Impact 

Axius Water strives to reduce greenhouse gas emissions, both directly in operations and through the implementation of technologies at customer sites.  Because up to 70% of a typical wastewater plant’s energy consumption may be used to power the aeration process, EDI assists customers in optimizing their energy use by replacing, maintaining, or investing in the aeration process. EDI’s distinctive matrix membranes were designed specifically to operate at the lowest energy requirements for the longest interval, enabling customers to drive down their power requirements.

Waste Management 

While most of our operations do not involve or generate significant amounts of waste, we employ policies and procedures as necessary for the treatment, handling, storage, disposal, and regulatory compliance related to hazardous and nonhazardous waste, including chemicals.  EDI and Nexom meet all requirements for the disposal of hazardous waste from operations. Most production processes do not produce hazardous waste.

Valuing People 

Diversity, Equity, and Inclusion 

We focus on creating a workplace in which employees feel welcome, affirmed, and safe.   Axius Water is committed to creating workplaces that welcome and support people of all backgrounds. Soon, we are hoping to implement a DEI training program at EDI as well as ensuring the presence of an Affirmative Action/Equal Employment Opportunity program this upcoming year.  

Worker Well-being 

Our goal and responsibility is to return our valued employees safe and healthy to their families and loved ones every day. Our employees are mindful of maintaining robust health and safety programs that incorporate industry best practices and closely monitor our performance.  EDI experienced three recordable employee injuries in 2021. In response, we have instituted Six Sigma standard protocols as it implemented routine observation facility walks to identify possible safety risks and proactively resolves any found issues. Reach out to our HR team to see about joining our growing team. 

Responsible Business 

We operate according to the principles of responsibility and reliability so stakeholders can depend on us.  

Sustainability, Governance, and Strategy 

We place consideration of ESG issues at the forefront of everything we do because we believe it’s the right thing to do. While responsibility for Axius’ ESG performance is shared by the Axius Water leadership team, in 2021, the company appointed the senior vice president of operations to lead and coordinate Axius’ ESG initiatives. The Axius Water board of directors reviews Axius’ ESG performance as part of its quarterly business planning and review process. 

Business Continuity 

Axius’ operating companies strive to build operational resilience and maintain business continuity because wastewater treatment facilities must operate continuously, through all weather conditions, and thus require an uninterrupted supply of consistent quality products. EDI strives to build operational resilience and maintain business continuity to assure that we can deliver critical raw materials even during market disruptions. 

Supply Chain Management 

Like Axius Water’s other operating companies, EDI took steps to strengthen oversight of labor, human rights, environmental, and diversity issues with their respective supply chains in 2021, with ATAC leading the way. We took steps to strengthen oversight of labor, human rights, environmental, and diversity issues with our respective supply chains in 2021.  

Risk Management  

At both the platform and operating company levels, Axius Water’s senior leaders take various actions to identify, assess, and manage ESG and other risks and opportunities. For example, in 2021, Axius recognized a risk management vulnerability and identified the need to more clearly articulate the scope and limits of authority delegated by Axius across the day-to-day operations of their companies. In response, in early 2020, Axius developed and adopted a Delegation of Authority policy covering commercial transactions, capital expenditures, employment matters, banking/treasury/investment matters, contributions and changes to the corporate structure, legal entities, and mergers and acquisitions.

Serving Customers 

We draw on decades of experience to create economical, effective, and sustainable solutions for clean water, and our customers define success using many terms, such as SOTE, power, space, NPV, Total N, P, BOD, and TSS. These terms may be rather technical, but what our customers really want is a positive outcome, not a product.   Our highly experienced professionals have been offering deep application knowledge backed by unique services and technologies to assist our clients in providing cleaner, healthier water in communities around the world for 47 years. We design and implement innovative, cost-effective, sustainable solutions that help clients maintain compliance of the contaminants and nutrients that regulators are targeting today and into the future. Our ability to solve customer problems is evidenced by the number of our staff members who previously worked for one of our customers and were so impressed with our service level that they chose to join our team and provide that service level to other customers. 

Building Local Economies 

EDI has deep roots in its local and regional community. We contribute to vibrant economies by providing rewarding careers, depending on local suppliers, and contributing to the expansion of U.S. exports. EDI has received both the Missouri Small Business Exporter of the Year Award and the U.S. Department of Commerce President’s ‘E’ Award for Excellence. Also known as the E-Star Award, this recognition is the highest recognition any U.S. entity can receive for making a significant contribution to the expansion of U.S. exports and has only been granted to 300 companies since its inception. Read more about how EDI continues to serve their community and country.

Research-Based Solutions 

In addition to conducting disciplined Research and Development and extensive analysis of customer-specific needs, we can draw on years of data from dozens of full-scale installations that have been meeting rigorous regulations and recognized academic authorities and regulatory agencies. In a field in which experience matters, EDI’s people have been solving aeration challenges for 47 years. 

Innovating for a Better Tomorrow 

Axius Water’s operating companies offer proprietary, eco-friendly treatment products and services that can replace outdated methods with current best practices and utilize information technology to enhance and remotely control process management. 

“At EDI, we value the voice of the customer and look beyond what standard “commodity” systems can offer. We have almost 50 years of aeration innovation and have always placed the highest regard on value for our customers while simultaneously recognizing our corporate mission: being good stewards of the environment.”Patrick Ely, Regional Sales Manager, EDI Employee since 1988 

Water Infrastructure Investments 

In response to prolonged underinvestment in water infrastructure in the United States, the Bipartisan Infrastructure Law enacted in 2022 delivers more than $50 billion to the EPA to improve U.S. drinking water, wastewater, and stormwater infrastructure. Axius companies are advising and assisting customers on how they can best access and utilize funding from the single largest investment in water that the U.S. federal government has ever made. Axius operating companies possess innovative water treatment technology that can help customers achieve aggressive clean water goals and build future-focused solutions for the 21st century.  As U.S.-based manufacturers, both EDI and Nexom produce clean water technologies that are eligible for projects funded under the Build America, Buy America Act, which is part of the Bipartisan Infrastructure Law. Find out which EDI product is the best fit for your BABA project.

EDI in Action: Piscataway wastewter treatment Plant

A complex, coordinated system upgrade is helping to restore the Chesapeake Bay, one diffuser at a time.

Located in a rural section of Prince George’s County, Maryland…

the Piscataway Wastewater Treatment Plant treats water that enters an environmentally sensitive area of Piscataway Creek before it flows into the Potomac River. Expanded twice since it was built in 1967, the sophisticated plant treats 30 million gallons per day, removing suspended solids, organics, ammonia, nitrogen, and phosphorus. In 2021, EDI played a critical role in upgrading the plant by installing 18,400 units of FlexAir Pro 9” Disc Diffusers with EDI’s proprietary Matrix Plus membranes for the fixed-grid aeration system. The plant has four basins and 96 unique zones, each with different layouts, designs, piping, and independent shipping requirement, making this a mammoth undertaking. Also, quick installation was crucial because taking one of the basins off-line during installation significantly impacted treatment capacity. EDI’s solution included factoryconfigured Smart Packaging, in which EDI delivers equipment for each tank and zone with color-coded pallets to make inventory and installation easier and faster for the contractor. In coordination with the materials contractor and engineering firm, the tenacious EDI crew persevered through snowy weather and installed the system during the winter of 2021, with a final startup in January 2022. Since then, the plant has operated smoothly, removing nutrients and biological oxygen demand (BOD) and protecting the delicate balance of water in the Potomac estuary.
