EPA's Decentralized Wastewater Management Memorandum of Understanding (MOU) Partnership

EPA and 20 partner organizations are joined by an MOU to work collaboratively at the national level to improve decentralized performance and protect the nation's public health and water resources. EPA initiated this MOU partnership in 2005 through an MOU with eight public and private sector organizations. The MOU has expanded over the 15 years, comprised of 20 partners as of September 23, 2020.

The 2020 MOU renewed the commitment of EPA and its partner organizations to work together to encourage proper management of decentralized systems and increase collaboration among EPA, state and local governments, and decentralized system practitioners and providers.

2020 MOU Signing Event

At the MOU signing event, 20 public and private sector organizations expressed their intent to work together to improve management of decentralized wastewater. (Note, due to the 2020 MOU Partnership renewal meeting being a “virtual” event, the image shared below is from the 2017 renewal meeting.)
