Enhanced Onsite Wastewater Treatment Options

Peconic Green Growth is pleased to announce that it has developed an informational resource on enhanced wastewater treatment available on the web for people wishing to upgrade their onsite wastewater treatment systems.

The project was funded by the Long Island Community Foundation.


The site is:

or one can navigate the website through the environment tab at .


The site provides a general understanding of enhanced treatment and the typical classifications of enhanced treatment technologies, also called innovative/alternative onsite wastewater treatment systems or I/A OWTS. The site then delves into specifics with a technology comparison chart and two-page data sheets on each technology. When shopping for systems, property owners need to evaluate which systems work best for their uses, site conditions, levels of treatment, and budgets. Maintenance and energy needs are other considerations.

Water quality is a critical concern for the eastern end of Long Island, where roughly half of onsite systems are outdated. The existing cesspools and septic systems do not treat for nitrogen adequately enough to protect the quality of aquifers and surface waters. The growing number of algal blooms and fish kills is proof of the need to act. While Suffolk County is just finishing one pilot and starting another, as it tests technology for applicability in our region, the County now allows people to install some form of enhancement. The choices will increase rapidly over the next couple of years. This website will help people to make an informed decision and be prepared to take advantages of incentives when and if they occur.

As people and organizations turn to Peconic Green Growth for advice on systems, the non-profit organization, with support from the Long Island Community Foundation and its generous donors, felt that a third-party introduction to both proprietary and non-proprietary solutions would serve people’s needs while helping to accelerate the installation of upgraded treatment systems. Only a concerted effort will help restore our water quality.
