Aerobic Treatment Units (ATUs) are advanced septic systems that treat wastewater more effectively than traditional tanks. However, to function properly, they require regular professional maintenance. At Rob’s Septic Tanks, Inc., we’ve specialized in ATU care across Central Florida for over 40 years, keeping systems efficient, compliant, and environmentally safe.

What Is an Aerobic Treatment Unit (ATU)?

An ATU is a small-scale wastewater treatment plant for your home. Instead of relying solely on anaerobic bacteria, it introduces oxygen to break down waste faster and cleaner.

✅ Cleaner effluent — Reduces environmental impact and odor.
✅ Compact design — Ideal for smaller lots or high-water-table areas.
✅ Longer drainfield life — Treated water reduces soil clogging.

In Florida’s sandy soils and dense communities, ATUs are becoming the preferred solution for reliable wastewater management.

Why ATU Maintenance Is Crucial

Unlike traditional septic tanks, ATUs have mechanical and electrical components that require regular servicing. Ignoring maintenance can lead to expensive failures, system shutdowns, or even environmental violations.

✅ Air compressors and blowers must run continuously for oxygenation.
✅ Filters and diffusers need periodic cleaning to prevent clogs.
✅ Chlorinators and pumps require checks for proper disinfection.
✅ Control panels and alarms must be tested to ensure safe operation.
