• save on water bills
• arguably, contribute to environmental sustainability and defer new dam construction.

• RAINFALL
  The average annual rainfall, the pattern of distribution throughout the year and the variation from year to year.
• ROOF AREA
  Which places an upper limit on the amount of water that can be collected.
• ACCEPTABLE LEVEL OF SECURITY
  The risk or possibility of the tank running dry. A higher level of security will be required where tanks are the sole source of supply.
• DEMAND
  Which varies enormously from household to household and season to season depending on:
  • number of people in the household.
  • their water use habits
  • what the rainwater is used for.
  • the number and type of water saving appliances.

Where a tank is to provide an alternative or secondary supply (eg to mains water), the size of the tank is not such a critical issue and often will depend on considering user requirements (watering garden, car washing etc) balanced against cost.
