5.1 AES Infiltration Bed Design.            Advanced Enviro-Septic System

The AES Bed Design is to be a gravity fed, below ground system. See system design drawings page 6.

The total bed base required is 36m2 (9m x 4m). Bed is to be installed as shown on the site plan. See drawings page 6 for bed
profile. A minimum 4m setback is required to any tree.

The entire bed base it to be ripped 250mm parallel to the AES pipes and gypsum applied at 1kg per m2.

Coarse washed sand will be referred to as “system sand” and must meet the specifications of the system manufacturer.
System sand will need to be placed around AES pipework and for the infiltration area as shown on the attached drawings.

System pipe bed dimensions (Area A) are 6.6m x 1.35m and a total minimum sand depth of 750mm. 300mm of course washed
sand is to be spread to form a base and 2 rows of 2 lengths of AES pipes installed as per the attached drawings.

A further infiltration area (Area B) is to be constructed around and below the pipe bed as per the site drawings and a minimum of
150mm system sand to be spread over the entire infiltration area.

Pipes are to be covered by a minimum of 150mm of system sand. A further 150mm of site soil is to be mounded over the sand to
prevent surface water entering the bed. After all settlement the AES Bed is to have a minimum 150mm cover of site soil.

Beds are to be constructed in accordance with the AES Design and Installation Manual and all plumbing works in accordance with
the QPW code. All site work is to be carried out by a licenced plumber and all AES horizontal pipes layed with the aid of a laser
or dumpy level to ensure absolute compliance with the manufacturers installation guidelines. This is critical for correct operation.

Oxygen Demand Vents are to be installed as per the AES Design & Installation Manual. The high vent (100mm - on the studio)
must be a minimum of 3m higher than the AES low vent and provide unrestricted air flow through the entire system.

Two Inspection Ports are to be installed, one in the centre of the pipe bed and another at the furthest point from the influent to AES
Pipes. See Installation Instructions Appendix A - page 11.

Care must be exercised to prevent machinery access on the AES bed during and after construction.
