Site Preparation For South Australian Conditions
How you can get your property ready for your water storage tank? Right before most water tanks can be put in, a sand pad foundation must be prepeared. There are some necessary things to think about when choosing your tank site and readying the pad:
Prepare your Property
The sand pad must be level, stable and free of clutter preceding building.
The sand pad must be at least two metres bigger than the diameter of your rainwater tank.
For sloping tank sites, ensure sufficient drainage to redirect run off from the tank wall.
Aggregate must be positioned around the area of your tank to eliminate erosion and meet warranty conditions.
A retaining wall may be required to ensure pad integrity.
Your tank should not be left empty for an extended time frame. A minimal load of water (10% of tank capacity) should be maintained in your tank at the completion of construction.
Although a correctly prepared sand pad will reduce the risk of contaminants or debris jeopardising the security of your water supply, Pioneer Water Tanks South Australia also recommends installing a underlying geotextile membrane for added protection of your tank liner.
Before you start preparing your site for installation of your water tank, Pioneer Water Tanks South Australia also advises you to get in touch with your local shire to see if there are any planning policies or requirements in place.
