AES Brochure

AES Certified

Sign up to the AES certification course here. It provides in-depth information on designing and installing a secondary wastewater treatment system and specifically the AES system. This is available to anyone interested in understanding more, but especially designers and installers.

“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 is 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 Drain Layers has been positive and they find it very simple to install with very thorough manuals provided by the supplier.”
