Aerobic Wastewater Treatment Systems (AWTS), or Package Treatment Plants:

There are a growing range of on-site wastewater treatment systems available today including the traditional Septic Tank system along with newer treatment systems such as Aerobic Wastewater Treatment Systems (AWTS), Wet Composting Systems, Sand Filtration Systems and Electro-flocculation Systems.

1) Traditional Septic Systems - Septic tanks have been used in un-sewered areas for many years as the most suitable form of primary treatment of sewage.

The septic tank is an underground watertight tank generally constructed of concrete or plastic which is usually divided into at least two compartments. The tank receives all sewage and separates the solid portion of the waste from the liquid portion. The liquid portion (effluent) passes out of the tank after approximately 24 hours.

The tank performs three functions:
 It acts as a settlement chamber for solid materials
 It allows some bacterial breakdown of waste materials to occur
 It acts as a storage chamber for undigested solid materials which must be removed periodically (usually every 4 years)

A number of problems can arise from their use and poor maintenance including:

 Sludge accumulating in the tank filling household pipes may become filled with sewage and clogging of the subsoil soil trench system solids.
 Effluent rising to the surface posing a risk to public health, particularly to children playing in the vicinity.
 Unpleasant smells emanating from the system.
 A breeding ground for mosquitoes
 After a number of years of use, some soakage systems may fail and require replacement.

2) Aerobic Wastewater Treatment Systems (AWTS)

An aerobic wastewater treatment unit is designed to treat septic tank effluent to a level suitable for surface irrigation within the site. The unit may incorporate a septic tank or it may be separate. Following primary treatment in the septic tank, the effluent is treated by a process of aeration, settling and disinfection and then pumped to a dedicated irrigation area as reclaimed water.

Aerobic wastewater treatment systems have a series of treatment processes such as aeration followed by clarification to breakdown and treat the wastewater, which is then disinfected, usually by chlorine, before pumping the treated effluent over the land.
