Frequently Asked Questions About ATU / Nitrogen-Reducing Septic Systems
What is an ATU septic system?
An ATU (Aerobic Treatment Unit) septic system is an advanced wastewater treatment system that uses oxygen to break down waste more efficiently than traditional septic tanks. In Florida, many homeowners choose ATUs because they significantly reduce nitrogen levels in wastewater, helping protect local waterways.
Why are nitrogen-reducing septic systems important in Florida?
Florida’s sensitive ecosystems, especially in Central Florida and the Orlando area, can be harmed by nitrogen pollution. Nitrogen-reducing ATU systems help meet Florida Department of Environmental Protection (FDEP) requirements and protect lakes, springs, and groundwater from contamination.
How does an ATU system work?
An ATU uses an aeration chamber where air is pumped in to promote the growth of beneficial bacteria. These bacteria break down waste more thoroughly, reducing nitrogen and other contaminants before the water is safely released into the drain field.
Is an ATU septic system required in my area?
Some Florida counties and environmentally sensitive areas require nitrogen-reducing septic systems for new installations or replacements. Contact A1 Septic Orlando to find out if your property falls under these requirements.
Can A1 Septic Orlando install and maintain ATU systems?
Yes. Our certified technicians provide ATU installation, inspections, repairs, and maintenance throughout Orlando, Winter Park, Apopka, Kissimmee, Sanford, and other Central Florida communities.
How much does an ATU septic system cost?
Costs vary based on the size of your property, system requirements, and installation complexity. At A1 Septic Orlando, we provide free estimates and can help you explore financing options to make your nitrogen-reducing septic system more affordable.
