Service Overview
ATU Inspection Backed by 65+ Years of Local Experience
Your aerobic treatment unit (ATU) works harder than a conventional septic system — and that means it needs regular, professional inspections to stay safe, compliant, and functioning the way it should. Florida law requires permitted ATU systems to be inspected on a regular maintenance schedule, and skipping those inspections doesn't just put you at risk of fines — it puts your family and property at risk too. Lapin Services has been inspecting and maintaining ATU systems across Central Florida since 1958, and our licensed master septic contractors know exactly what to look for.
Whether you're due for a routine inspection, received a notice from Orange, Osceola, or Seminole County, or you've noticed something isn't quite right with your system, we're ready when it happens. Our team handles the full inspection, documents everything required for county compliance, and lets you know if any repairs or adjustments are needed — no runaround, no surprises.
Problems We Solve
Common ATU Inspection Problems We Fix
Here are the issues our team commonly finds and resolves during atu inspection calls across Central Florida.
Missed or Overdue Maintenance Inspections
Florida requires ATU owners to maintain a service contract and keep up with scheduled inspections. Many homeowners don't realize they've fallen behind until they receive a county notice or violation. Lapin can get you back on schedule fast and handle all required documentation.
Air Pump and Aerator Failure
The air pump is the heart of an aerobic treatment unit — it keeps the aerobic bacteria alive and working. When it fails, the system stops treating wastewater properly. Our inspectors check pump performance at every visit so small issues get caught before they become costly failures.
Chlorinator Depletion or Malfunction
ATUs disinfect treated effluent with a chlorinator before dispersal. An empty, clogged, or malfunctioning chlorinator means untreated water is reaching your yard — a health hazard and a compliance violation. We inspect and service the chlorinator system as part of every maintenance visit.
Control Panel Alarms and Electrical Issues
ATU control panels monitor system performance and alert you when something's wrong. A flashing light or audible alarm is your system telling you it needs attention. Our technicians diagnose control panel faults, reset alarms where appropriate, and identify the underlying cause so it doesn't keep coming back.
Effluent Dispersal Problems
ATUs spray or drip treated effluent into your yard through a dispersal system. Clogged heads, broken lines, or saturated soil can cause pooling, odors, and system backups. We inspect the full dispersal field to make sure treated water is being distributed safely and evenly.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these warning signs, schedule atu inspection before the problem becomes more disruptive or expensive.
Your Alarm Light or Buzzer Is Going Off
An active alarm on your ATU control panel means the system has detected a problem — don't ignore it. Our technicians will diagnose the fault, clear the alarm, and make sure the underlying issue is resolved before we leave.
You Received a County Notice or Violation
Orange, Osceola, Seminole, and other Central Florida counties actively enforce ATU maintenance requirements. If you've received a notice or compliance letter, Lapin can complete the required inspection, generate the proper documentation, and help you respond to the county — we've done it hundreds of times.
You Can't Remember Your Last Inspection
Most ATU maintenance contracts require inspections every 4–6 months. If you're not sure when your system was last checked, now is the right time to schedule one. Staying ahead of the schedule is always cheaper than dealing with a system failure or compliance fine.
Odors Near Your Yard or Spray Heads
Foul odors around your yard, near your ATU, or at spray head locations can signal a chlorinator issue, dispersal problem, or system overload. These smells don't go away on their own — and they can indicate a health risk that needs to be addressed promptly.
You're Buying or Selling a Home with an ATU
If you're purchasing a property with an aerobic treatment unit — or selling one — a professional ATU inspection gives you a clear picture of system condition. We provide thorough written reports that protect buyers and help sellers avoid surprises at closing.

FAQs
ATU Inspection FAQs
How often does an ATU need to be inspected in Florida?
Florida requires aerobic treatment units to be covered under a maintenance contract with a licensed septic contractor. Inspection frequency depends on your county and system permit, but most ATUs in Central Florida require inspections every 4 to 6 months. Orange, Osceola, and Seminole counties each have specific requirements — Lapin knows all of them and can make sure your system stays compliant.
What is an ATU and how is it different from a regular septic system?
An aerobic treatment unit (ATU) uses an electric air pump to inject oxygen into the wastewater, which accelerates bacterial breakdown and produces a higher-quality treated effluent than a conventional anaerobic septic system. Because ATUs treat wastewater more thoroughly, they’re often required on smaller lots or in areas with poor soil conditions. They also require more active maintenance — including regular inspections, chlorinator servicing, and air pump monitoring.
What does a Lapin ATU inspection include?
Our inspections cover the full system: air pump and aerator function, all tank compartments and liquid levels, control panel and alarm status, chlorinator level and condition, spray heads or drip dispersal components, and the overall yard dispersal field. We document everything required for county compliance and service what we can on the spot — including chlorinator recharging and spray head cleaning.
My ATU alarm is going off. Is it an emergency?
An active alarm means your system has detected a problem — it could be something minor like a float switch triggered by high water, or it could indicate a pump failure or electrical issue that needs immediate attention. Don’t ignore it. Call Lapin at (407) 326-3367 and we’ll help you assess the situation quickly. We’re available 24/7 for septic emergencies.
Can Lapin help if I've received a county compliance notice for my ATU?
Absolutely. We handle county compliance issues regularly. Our licensed technicians will perform the required inspection, complete all necessary paperwork, and can communicate directly with county inspectors on your behalf if needed. We’ll help you understand exactly what’s required and get your system back into compliance as quickly as possible.
How much does an ATU inspection cost in Orlando?
ATU inspection costs vary depending on your system type, current maintenance contract status, and whether any repairs or service are needed during the visit. Lapin provides transparent, upfront pricing before any work begins — no surprise charges. Call us at (407) 326-3367 for a quote, or ask about our ATU maintenance contract options, which often provide the most cost-effective way to keep your system compliant year-round.
