20140828_Des&Install_Tab_50_01In an effort to provide product support to septic professionals, Presby Environmental offers Enviro-Septic® Technology certification classes free of charge. In most states, certification is required in order to design or install an AES or Enviro-Septic® System (CEUs/TCHs/PDHs may apply). See your state page on this website for details on certification requirements and CEUs/TCHs/PDHs. The classes are a great way to learn more about our product, even if not seeking certification. Support in reviewing your first several plans is available to certification class graduates.
