Sadly more often than not, facilities provided by National Parks that enable all members of our community to enjoy the experience offered our wonderful natural environment, is impacted by idiots.

We recently received a request from National Parks for a vandal proof low vent for our AES systems. With dozens of National Park sites now benefiting from the low capital, operational cost and Advanced Secondary treatment provided by Advanced Enviro-Septic. Our Vandal Proof Oxygen Demand vent is now available.


Made from 1.6mm Aluminium with 3 screwed lugs and the stainless gauze vent cowl inside. It can be concreted into the ground and the lid can be welded on if requested. Cost is $90 per unit in addition to the normal low vent cowl.
