HIGH WATER TABLE SUPPLEMENT

If the Bio-Pure is installed in wet ground the top and bottom parts of the unit should be sealed by means of a water tight mastic sealant and the unit should be anchored by means of concrete or anchorage pins.

Anchorage by Concrete

The  Bio-Pure Domestic Sewage Treatment Plant has 4 anti-flotation wedges positioned on the sides. For moderately wet ground these can be covered in a lean mix of concrete to act as an anti-flotation ring. IN SEVERE WET GROUND THE ENTIRE UNIT SHOULD BE BURIED IN CONCRETE UP TO THE INLET AND OUTLETS OR THE ANCHORAGE PIN METHOD SHOULD BE USED.

NB. When using concrete the unit should be filled with water at the same rate as concrete is poured.

High Water Table Anchorage – Dry Pin Method

1. Insert the steel anchorage pins by hammering them horizontally
(90 degrees) to the walls of the excavation into the undisturbed ground at a depth of 1200 mm (from the top). The pins need to be inserted leaving 300 mm protruding into the excavated area.

2. Connect a length of galvanised chain into the hole in the end of each pin using a shackle. Take the loose end to the top of the excavation and secure temporarily.

3. Continue to install tank as per fitting instructions.

4. When the Bio-Pure Domestic Sewage Treatment system is fully installed, insert eye bolts into the down position

ie. Eye bolt at the bottom, nut at the top. Attach the loose end of the chain into the eye bolts by means of shackle, adjust and tighten each eye bolt to take up any slack in chain – do not leave any slack in chains as tank may move.

5. Continue to back fill to desired level.
