History of Advanced Enviro-Septic®

Advanced Enviro-Septic was developed by Presby Environmental Inc. (PEI), an innovative environmental organisation that engineers new technology to change the way the world approaches wastewater treatment. Founded in 1995 by inventor and entrepreneur David Presby, today the company is working at the cutting edge of water pollution control to help protect and preserve our most precious natural resources.

At the age of 14, New Hampshire native David Presby began his career apprenticing under his father at Presby Construction. In the 1980’s, while working with different aspects of the wastewater and construction industry, the lack of a reliable, cost effective approach to wastewater treatment motivated David to begin conceptualising what later became the Enviro-Septic® Technology. Over the years, through extensive testing and R&D, this technology evolved into the world’s most practical and effective wastewater treatment system, the Advanced Enviro-Septic™ Wastewater Treatment System (AES™). The Advanced Enviro-Septic solution provides an alternative to traditional septic tank systems.

Presby Environmental has continued to combine innovation, simplicity and extensive research and development into a patented line of complimentary onsite wastewater treatment technologies which are manufactured at PEI’s state-of-the-art facility in Whitefield, New Hampshire, USA.
