History

Presby Environmental Inc. (PEI) , founded in 1995 by inventor and entrepreneur David Presby, is  an innovative environmental organization that engineers new technology to change the way the world approaches wastewater treatment. 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 conceptualizing 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).

Presby Environmental has continued to combine innovation, simplicity and extensive research and development into a patented a line of complimentary onsite wastewater treatment technologies which are manufactured at PEI’s state-of-the-art facility in Whitefield, New Hampshire, USA. Presby Environmental is affiliated with two other companies, Presby Construction and Presby Plastics. These companies have specialized in onsite wastewater system manufacturing, design, installation, and maintenance for over 50 years.

Enviro-Septic Technology Today

After rigorous testing, Advanced Enviro-Septic has recently achieved NSF International Standard 40 Class I Certification.

With over a hundred thousand AES and Enviro-Septic Systems in the ground across New England, the Midwest and Canada, Presby Environmental is working hard to make this revolutionary technology available to citizens and organizations across the country, and across the globe.

Enviro-Septic Technology has provided onsite wastewater treatment solutions for private residence, subdivisions, cluster communities, resort communities, hotels, ski slopes, restaurants (including a number of McDonald’s), state parks (including Shendoah National Park in Virginia), laundromats, strip malls, farms, physician’s offices, condominium/apartment complexes and numerous other commercial facilities.

As a result of numerous competitive advantages Enviro-Septic Technology has enjoyed tremendous success in both the Canadian and US markets.

Whether it is a new or replacement system for your community or municipality, we are here to provide you with a proven environmentally safe system for the most value for your tax payer dollars.

The Advanced Enviro-Septic (AES) and Enviro-Septic Wastewater Treatment Systems are smart solutions for your community or municipality large flow needs.

Why Use Presby?

  • Low Maintenance Cost
  • Low Labor Cost
  • Longevity
  • Less Expensive

Cluster or STEP systems
As technology improves, “cluster” or “STEP” systems are becoming an increasingly popular solution to accommodate the sanitary needs of growing populations worldwide.

These community systems are designed to treat the wastewater from sections of a city, town, sub-division, resort area, or other groups of homes and businesses.

These systems provide a higher level of water quality protection, support the local water supplies, can easily accommodate growth, require less infrastructure, and make it easy to employ water reuse techniques.

With the incorporation of passive technology, communities are achieving these benefits with very little energy consumption, maintenance, chemicals, or additives; resulting in significantly reduced upfront and operational costs.

As part of Presby Environmental’s commitment to providing top-notch support we offer valuable tools to industry professionals and system owners.

Our experienced technical staff is available to speak with industry professionals directly or provide support via email.

History of Dependability

AES and Enviro-Septic® have an extremely low failure rate, and the unique ability to be “rejuventated” if the System is abused. It has become the “system of choice” in our home state of New Hampshire–accounting for 90-95% of system installations statewide in recent years. It has been in use in New England since 1995.

AES and Enviro-Septic® pipe is a proprietary device covered by numerous US Patents and manufactured exclusively by Presby Environmental/Presby Plastics.

Venting

Ongoing research proves that any onsite septic system will work better and last longer if it has a sufficient oxygen supply. For this reason, PEI is now recommending venting on all AES and Enviro-Septic® Systems. Given the minimal cost and effort it takes to add a vent to either a new or existing system, the benefits far outweigh any perceived detriments. Both of the following links provide a wealth of information.

System Sand

System Sand as specified in the state manuals is an essential component in the design and installation of Enviro-Septic®Technology. Presby Environmental maintains a System Sand Supplier Referral List for designers and installers. For information on System Sand Suppliers in your state, please see the Interactive Mappage.
