Burnham - Biodigester Installation Service

Excavate a hole 300mm wider and 200mm deeper than the relevant unit. Check the water table. If there is any chance of the water rising above the base of the unit then the Wet Ground method must be used. Install 200mm base of sand, gravel, scalpings or concrete. Place BIODIGESTER onto base, work ribs into base and check levels carefully. Fill the BIODIGESTER with water. If you have a high water table the Wet Ground anchors must be covered with at least 250mm of concrete to the minimum quantity specified by the data sheet.
