    Venting has been demonstrated to improve the functioning of the system and enhance its life-span.

    Ongoing research proves that any onsite septic system will work better and last longer if it has a sufficient oxygen supply. For this reason, PEI is now recommending venting on all Advanced Enviro-Septic™ (AES) and Enviro-Septic® Systems. Given the minimal cost and effort it takes to add a vent to either a new or existing system, the benefits far outweigh any perceived detriments.

    In most applications, the house roof vent will serve as the “high vent” and a “low vent” is installed at the far end of the treatment bed. Similar to a chimney, as light wind moves across the high vent opening, air is drawn in through the low vent, up through the system and out of the high vent. The low vent can be disguised or demoted, minimizing visual impact.
