ADS Supplier Code of Conduct 

At Advanced Drainage Systems, Inc., along with our directly and indirectly controlled affiliates, subsidiaries and joint ventures (collectively “ADS” or the “Company”), we understand the importance of solving modern water challenges. From the moment rain enters the drain until we safely return it to the environment, we are responsible for managing this precious resource. ADS engineers industry leading sustainable and resilient products. Environmental stewardship is at the core of our suite of solutions that provide opportunity to create broader access to clean water and sanitation, and importantly, it begins with our Suppliers. We strive to continually assess and better our supply chain that provides solutions vital to global infrastructure, working alongside sustainable suppliers. 

Purpose + Scope 

ADS is committed to conducting business fairly, honorably, with integrity and transparency, and in compliance with all applicable laws at all times throughout our supply chain. That fundamental commitment is reflected in our Code of Business Conduct and Ethics.  

ADS considers open communication and strong business relationships with our Suppliers an integral part of our commitment to conducting business with integrity and transparency. As such, ADS expects our Suppliers to share our ethical values and adhere to this Supplier Code of Conduct (the “Code”). ADS defines Suppliers as any organization or entity that directly provides goods and/or services to ADS, including its directly and indirectly controlled affiliates, subsidiaries and joint ventures.     

This Code provides the framework by which Suppliers are expected to maintain the highest ethical standards in conducting business and is an integral part of implementing our vision of maximizing value in an ethical environment. Accordingly, this Code references the Ten Principles of the United Nations (“UN”) Global Compact that ADS strives to uphold. 

Please review the Code regularly, as you are expected to adhere to it and ensure that your employees, agents, and subcontractors adhere to it, both in form and in spirit. The provisions of the Code are in addition to any agreement or contract between the Supplier and ADS and should also be read in conjunction with the ADS Code of Business Conduct and Ethics, Global Anticorruption Policy, and other applicable policies. If you have any questions or concerns, please reach out through appropriate ADS channels, listed at the bottom of the Code, to address them. 

ADS considers collaboration in the supply chain an integral part of our success and strives to operate as an integrated team with Suppliers. We look to select Suppliers based upon their ethical standards in conducting business, as well as on the quality and competitiveness of their products and services. We look for strong progressive social and environmental programs in addition to pervasive business ethics. ADS’s Supplier Code of Conduct assists us in choosing and maintaining business partners who share similar principles and values. Our requirements in the Code are borderless and global in nature; however, if a local law or regulation is inconsistent with a contained policy, the Supplier should adhere to the local law or regulation. Suppliers are expected to be familiar with the business practices of their suppliers and subcontractors, and ensure they operate according to the Code. ADS reserves the right to terminate its relationship with a Supplier that fails to comply with this Code. 


Environment – Sustainability 

As one of the top plastics recyclers in the United States and a leading water management company, we are guided by our commitment to preserve and protect water.  ADS expects our Suppliers to share our commitment to reduce consumption, reuse consumer products and preserve precious resources in order to protect the environment. ADS does not tolerate violations of laws, rules, or regulations on environmental safety and precautions. Suppliers must store, handle, and dispose of hazardous materials in accordance with applicable law.  

ADS seeks strong business relationships with Suppliers willing to go beyond regulatory requirements to protect the environment, through efforts of recycling and conserving energy and natural resources. ADS encourages Suppliers to consider new ways to protect our environment through innovation, implementation, and promotional activities. 


ADS has committed to setting science-based targets for Greenhouse Gas Emissions (GHGs) in line with the Paris Agreement and limiting the global temperature increase to 1.5°C.  Our GHG emissions reduction goal once approved by the Science Based Targets initiative will include reductions in GHGs from the fuel we burn in our operations and fleet (scope 1) as well as the energy we purchase (scope 2) and will also include a scope 3 reduction target. Based on our analysis, most of our scope 3 emissions can be attributed to our Suppliers.  Therefore, we expect all our Suppliers to focus on reducing GHG emissions within their respective footprints as well.   

Water is Precious
