Your domestic water tank can be used in many different areas of your home, but your entire system needs to be properly setup to ensure the water is fit for the task.  

For example;

A rain water tank which collects rainwater from a roof guttering system is likely to encounter all sorts of unwanted material, which could not only cause blockages, but could also contaminate the water.  Filters and screens may be required to prevent leaves and branches from entering the tank, and guttering may need to be checked to ensure it does not contain any lead.

If your water tank is connected to a toilet or washing machine, a constant pressure and flow of water will be required.  Domestic water tanks can be connected to 'mains' or drinking supply water as a backup in this situation, so when the water tank level is too low, it can be automatically filled.  You can also employ a control valve so that the source of water is switched over to 'mains' water supply.


A domestic rainwater tank can be used for the following:

• toilet flushing
• washing clothes
• water heating systems
• garden watering
• car washing
• filling swimming pools
• spas and ornamental ponds
• fire fighting
