Advanced Enviro-Septic® Now approved in the state of North Carolina

We are proud to introduce the Advanced Enviro-Septic® Treatment System (“AES”) to North Carolina. Advanced Enviro-Septic® is the next generation of our effective and reliable Enviro-Septic® technology; it has received Class I Certification under NSF International/ANSI’s Standard 40 for Wastewater Treatment Devices. The reduced bed size of the Advanced Enviro-Septic® will allow it to be smaller than traditional stone trench systems.

Certification Classes

We require individuals who wish to design or install an Advanced Enviro-Septic® be certified by attending the Advanced Enviro-Septic® Design and Installation Certification Class offered by Presby Environmental authorized personnel or to view the online training videos (see below). The class offers various design and installation configurations, troubleshooting techniques and tricks of the trade. All professionals involved in the review or approval of Presby systems should also become certified.

As an important part of your training, please watch this orientation video by the inventor David W. Presby
