Frequently Asked Questions

What’s the difference between a septic system and an onsite wastewater treatment system?

A septic system is a basic OWTS using gravity for simple waste separation. OWTS also includes advanced systems, like aerobic units, that use electricity and aeration to better treat wastewater and produce cleaner effluent than standard septic systems.

What is an Innovative/Alternative Onsite Wastewater Treatment System (I/A OWTS)?

An I/A OWTS is an advanced wastewater treatment system designed to reduce nitrogen pollution and treat sewage more effectively than traditional septic systems, especially in environmentally sensitive areas.

Is an I/A OWTS required for properties on Long Island?

Many areas across Long Island now require I/A OWTS for new builds and septic upgrades, especially in environmentally sensitive or high groundwater zones, to meet local wastewater treatment regulations.

How does an I/A OWTS work?

I/A OWTS units treat wastewater in multiple stages using aeration and filtration to remove contaminants before safely returning water to the ground, reducing pollution and improving groundwater protection.

What are the benefits of using an I/A OWTS?

Key benefits include reduced nitrogen discharge, improved water quality, compliance with county regulations, smaller system footprint, and eligibility for grant funding or rebates.

How long does it take to install an I/A OWTS?

Most I/A OWTS installations are completed within 1–3 days after obtaining necessary permits and health department approvals.

How often should an I/A OWTS be serviced?

Maintenance is typically required every 6–12 months to inspect, clean, and ensure the system meets operational standards set by the manufacturer.

Can I convert my old septic system to an I/A OWTS?

Yes, many older septic systems can be upgraded to I/A OWTS to meet current environmental regulations and improve system performance.

Are grants or rebates available for I/A OWTS installation?

New York State offer financial assistance programs to help offset the cost of installing approved I/A OWTS units.

What types of properties are eligible for I/A OWTS systems?

I/A OWTS solutions are ideal for both residential and commercial properties without sewer access, especially in areas with high groundwater or environmental sensitivity.
