The AES Process

AES Revolutionises Domestic Waste Water Treatment
AES is a passive, onsite wastewater treatment system developed and in use in the USA for over 20 years with over 400,000 installations.  The effluent is treated using natural bacterial processes within specially-designed, passively aerated pipes laid in a sand bed following a standard local septic tank.  In its simplest form the treated effluent is dispersed passively into the soil beneath the bed, or can be collected and used for irrigation if preferred.

AES provides 10 x the results recommended by the AUS/NZ Standards without the use of power or chemicals providing a cleaner output into groundwater resources and soil.
