I have been designing wastewater systems in Southland since 1978 and I have to say that the AES system is quite simply the best solution that I have come across in all that time.  My clients love it because it’s maintenance-free with no pumps or filters.  The AES system provides secondary treatment to an extremely high level so it’s very kind to the environment also.  The feedback I have had from Drainlayers has been positive and they find it very simple to install with very thorough manuals provided by the supplier.
