Service Overview
ATU Disinfection System Service Backed by 65+ Years of Local Experience
An aerobic treatment unit (ATU) doesn't just treat wastewater — it's required to disinfect it before it's dispersed. That disinfection component is a critical part of your system, and when it fails or runs out of disinfectant, you're not just out of compliance — you're putting your family and property at risk.
Lapin Services has been servicing ATU disinfection systems across Orlando and Central Florida for decades. Our licensed technicians know exactly what your system requires, handle all refills, repairs, and inspections, and make sure you stay compliant with county and state regulations — no guesswork, no shortcuts.
Problems We Solve
Common ATU Disinfection System Service Problems We Fix
Here are the issues our team commonly finds and resolves during atu disinfection system service calls across Central Florida.
Empty or Depleted Chlorinator
The most common disinfection issue is a tablet feeder that's run dry. Without a steady supply of disinfectant, treated water is dispersed without proper sanitation — a compliance violation and a health concern.
Clogged or Blocked Tablet Feeder
Residue, scale, or debris can clog the chlorinator or tablet feeder, preventing disinfectant from reaching the effluent even when tablets are present. This often goes unnoticed until a required inspection.
Disinfection System Component Failure
UV lamps, chlorinators, tablet feeders, and related hardware wear out over time. A failed component means your system isn't disinfecting — regardless of what the rest of the ATU is doing.
County Compliance Violations
ATU systems are subject to mandatory county inspections and maintenance contracts. A malfunctioning or unserviced disinfection system can result in violations, fines, and required emergency remediation.
Alarm or Warning Light Active
Many ATU systems include alarms that trigger when the disinfection system isn't functioning correctly. An active alarm should never be ignored — it's a signal that something needs immediate attention.
When to Call
Signs Your Septic System Needs Professional Attention
If you notice any of these warning signs, schedule atu disinfection system service before the problem becomes more disruptive or expensive.
Your ATU Alarm Is Going Off
An alarm light or audible alert on your ATU panel is often the first sign that the disinfection component has failed or the chlorinator needs attention.
You're Due for a County-Required Inspection
ATU systems in Florida require regular inspections and maintenance under a permitted service contract. If you're coming up on your inspection window, it's time to schedule a service visit.
You Haven't Had the System Serviced in Over a Year
Most ATU maintenance contracts require service every 4–6 months. If it's been more than a year since your last visit, the disinfection system may be depleted or malfunctioning without any obvious signs.
Odor Near the Spray Heads or Dispersal Area
A sewage or chemical odor near the spray heads or drip lines can signal that treated water isn't being properly disinfected before it's dispersed.
You've Received a Notice of Non-Compliance
If the county has flagged your ATU system for a disinfection issue, you need prompt professional service to resolve it and document the repair before reinspection.

FAQs
ATU Disinfection System Service FAQs
What does an ATU disinfection system do?
An aerobic treatment unit (ATU) treats wastewater through an aeration and settling process. The disinfection component — typically a chlorinator or UV system — kills pathogens in the treated effluent before it’s dispersed into the soil or through spray heads. It’s the final step that makes the treated water safe.
How often does an ATU disinfection system need to be serviced?
Most ATU systems in Florida require service every 4–6 months under a mandatory county maintenance contract. The disinfection component typically needs chlorine tablets refilled at each visit, along with an inspection of all related components.
What happens if my ATU disinfection system runs out of chlorine?
If the chlorinator runs dry, your system continues treating wastewater but stops disinfecting it before dispersal. This is both a health risk and a county compliance violation. Untreated effluent can contaminate soil and groundwater near your property.
Is ATU maintenance required by Florida law?
Yes. Florida law requires ATU owners to maintain an active maintenance contract with a licensed contractor. The system must be inspected and serviced on a regular schedule, and service reports must be filed with the county health department.
My ATU alarm is going off — is this a disinfection problem?
It could be. ATU alarms can indicate a range of issues including a depleted chlorinator, a float sensor malfunction, pump failure, or a problem with the disinfection system itself. A licensed technician needs to inspect the system to diagnose the cause.
Can Lapin Services handle county reporting and compliance for my ATU?
Yes. We manage all required service documentation and reporting to the county on your behalf, so you stay compliant without having to track the paperwork yourself.
What is a chlorinator or tablet feeder on an ATU?
A chlorinator or tablet feeder is a housing unit that holds chlorine tablets and allows them to dissolve slowly into the effluent stream. As treated water passes through, it picks up enough chlorine to kill bacteria and pathogens before dispersal. When tablets run out or the feeder clogs, disinfection stops.
