What size water tank do I need?

The installation of a ‘large as possible’ rainwater tank and harvesting rainwater from your roof minimises the impact of water shortages and lessens your water costs.

  • Calculate your likely annual usage from the water storage requirement table below.
  • Using the water catchment table and the average rainfall for your area, calculate the amount of rainwater captured by your roof.
  • Now you can check your intended usage against the average annual catchment.
  • Identify your proposed water tank site and measure the space and height available.

Advantages of using plastic or polyethylene water tanks over other materials:

  • Old concrete water tanks can get calcium leaching out of the walls, forming white deposits.
  • Tin and galvanised iron or steel water tanks can react chemically with the water, especially minerals in bore water.
  • Plastic lined corrugated iron  water tanks sweat between the liner and the corrugated iron causing rust. The liner will split and is not vermin proof.
  • Fibreglass water tanks break down after a period of time.
  • Open top water tanks or water tanks with shadecloth over the top allow dirt, debris and sunlight into them causing algae growth.
