ATU Septic Systems
ATU Septic Systems- How Do They Work?
There are 3 main steps in the ATU Septic System. First there is a pretreatment where solids are separated and held in a separate tank or compartment off the main tank. The second step is the ATU itself, air is forced with an air-pump to introduce additional oxygen in the the tank. This process causes the bacteria inside the tank to grow at a rapid rate and intensifies the breakdown process. Once Broken-down the water and remaining solids flow to the settling tank. Here gravity separates the solids left with the water. This separation allows the treated water and effluent to then be discharged into the drainfield.
Any of the drainfield systems can be used including conventional, chamber, mound or drip.
Is There Maintenance for the ATUs?
Yes. In the state of Florida homeowners must maintain current operating permits for the system. This must be renewed every 2 years. You must also maintain a valid maintenance contract with an approved company. All City Septic has you covered with our maintenance program to maintain your ATU system.

ATU Septic Systems
ATU Systems are a great option for some homeowners depending on their situation. They don’t require a drain field like a septic system, making it possible to build homes on smaller lots or where drain field space is limited. Let’s take a quick look at the components of an ATU system to better understand how they work:
-
Pretreatment Tank-The main sewer line from your house empties into this tank. This is where solid waste remains while the effluent (liquid wastewater) continues to the ATU.
-
Aerobic Treatment Unit (ATU)-This is where the magic happens. And by magic we mean the aerobic bacteria breaking down waste particles in the water. Oxygen is injected into this unit to create the aerobic process. Usually the water will continue to a clarifying chamber or go through a chlorinator for further purification before entering the pump tank.
-
Pump Tank-After being treated, water enters the pump tank and is then distributed onto the soil through an irrigation system (sprinklers or drip irrigation). The microbes in the soil finish the purification process and the water returns to groundwater to be used again.
