Before most water tanks may be put in, a secure sand pad foundation must be prepared.
There are some essential things to think about when deciding on your tank site and preparing the pad:
The sand pad should be level, steady and without clutter before building.
The sand pad must be at the minimum two metres bigger than the diameter of your tank.
For uneven tank sites, make sure adequate drainage to divert run off from the tank wall.
Aggregate must be applied around the area of your tank to eliminate erosion and follow manufacturer’s warranty conditions *.
A retaining wall may be required to take care of pad integrity **.
Your tank should not be left unfilled for an extended amount of time. A minimum load of water (10% of tank capacity) should be stored in your tank at the finish of construction.
* Check with us to see if we can present this additional service. If not, you will need to ensure this is suitably applied after installation yourself
** 1,000 litres of stored water weighs 1,000 kgs (1 tonne).
Despite the fact that a successfully prepared sand pad will minimise the risk of contaminants or debris risking your supply of water, Pioneer Water Tanks Western Australa also recommends installing a geotextile membrane for added safeguards.
Before you start preparing your site for installation of your water tank, Pioneer Water Tanks servicing WA also advises you contact your local shire or council to see if there are any policies or limits in place.
