Wollongong Site Preparation

Did you know?

The best ways to ready your home for your rainwater tank

Even before most water tanks can be set up, a stable sand pad foundation must be prepared.

There are some vital things to think about when selecting your tank site and readying the pad:

Prepare your property



  1. The sand pad should be flat, secure and free of debris before construction.
  2. The sand pad must be at the very least two meters larger than the diameter of your tank.
  3. For uneven tank sites, ensure sufficient drainage to divert run off away from the tank wall.
  4. Aggregate must be installed around the circumference of your tank to stop erosion and comply with manufacturer’s warranty conditions *.
  5. A retaining wall may be necessitated to take care of pad integrity **.
  6. Your tank shouldn’t be left empty for an extended time period. A minimal load of water (10% of tank capacity) should be stored in your tank at the conclusion of construction.

* Check with us to see if we can provide this extra service. If not, you will want to ensure this is properly applied after installation yourself

** 1,000 litres of stored water weighs 1,000kgs (1 tonne).

Although a successfully prepared sand pad will reduce the risk of contaminants or debris jeopardising your water supply, Pioneer Water Tanks servicing the Wollongong area also advises installing a geotextile membrane for added protection.

Just before you start preparing your site for setup of your water tank, Pioneer Water Tanks servicing Wollongong also suggests you speak to your local shire to see if there are any guidelines or constraints in place.
