Everything You Need to Know About ATU (Aerobic Treatment Units) in Maui

There are a number of different methods that are used for treating wastewater in Maui. An ATU (aerobic treatment units) in Maui is very popular for people who don’t have a direct connection to the municipal sewage lines and need a proper method for treating the wastewater. In the simplest sense, this is a self-contained electrical wastewater treatment system that is used on properties which are independent of the main sewage lines. Here are a few important things that you should know about the ATU (aerobic treatment units).

The System

The system consists of a series of different chambers, known as treatment units, which are connected to a drain disposal system. The first chamber works similar to a conventional septic tank, as the solids sink to the bottom. In this chamber, aerobic digestion takes place by the bacteria, creating a layer of sludge on the floor. Oils and grease, known commonly as scum, floats to the surface, and the partially clear wastewater moves to the next chamber, where the liquid is mixed with organic matter. If there’s an issue with the tank, you should call a local company such as Valley Isle Pumping.


One of the key things that you need to keep in mind if you have an ATU (aerobic treatment units) installed in your house is that it needs adequate servicing. To keep it running smoothly, it is going to require regular servicing. If the system is not regulated and serviced after timely intervals, it won’t take long before a series of problems begin to arise. These are just a few things that you should know about these wastewater treatment systems and how they work. You can also connect with them on Facebook.
