There’s a national process (NSF Standard 40) for certifying aerobic treatment units and other small package treatment plants.There’s a national credential for installation professionals (National Environmental Health Association Certified Installer of Onsite Wastewater Treatment Systems). There’s a national onsite association (NOWRA). There’s a national group of regulatory officials (State Onsite Regulators Alliance).There’s a national Memorandum of Understanding between the U.S. EPA and a collection of onsite industry and water-quality partners. There’s a national Consortium of Institutes for Decentralized Wastewater Treatment, which sponsors nationally applicable training
