FREQUENTLY ASKED QUESTIONS
An ATU (Aerobic Treatment Unit) uses oxygen to break down and treat wastewater more efficiently than traditional septic tanks. This results in cleaner effluent and is often required in areas with high water tables or sensitive environments.
Most ATU systems require professional maintenance every 3–6 months, including inspections, cleaning, and calibrations. Proper maintenance is essential to comply with Florida regulations and ensure efficient operation.
Common signs include alarms sounding, foul odors, water pooling near the drain field, slow drains, or irregular noises from the unit. Contact us immediately if you notice any of these issues.
ATU systems rely on electricity. During a power outage, your unit may stop aerating wastewater. It’s best to minimize water usage until power returns and have us check the system after extended outages.
Yes, our technicians have extensive experience servicing all major ATU brands and models common in Central Florida, ensuring prompt repairs and reliable maintenance.
