Rainwater Harvesting Tanks

Rainwater is part of the never-ending water cycle. No single drop is lost or made in the continuous flow between seas, rivers, lakes and groundwater.

However, fresh water is an increasingly scarce, precious and expensive resource. Saving water is now an essential part of our drive to a sustainable society. Delivering clean tap water requires more and more effort, energy and expensive resource, so saving water is now essential in our drive towards an ecologically sustainable society.

For many everyday uses, we simply don’t need to use expensively purified drinking water, we need to use rainwater harvesting tanks. Harvested roof rainwater is not only a free resource, but is also ideal for appliances, toilet flushing and irrigation in domestic, agricultural, commercial, industrial and public sector environments.

Half of our future potable water demand can be met without any increase in effort.

Clear benefits for rainwater harvesting tanks for the environment and for us all include:

• Reduced flooding and overloading of sewers

• Prolonged appliance lifetimes • Softer water

• Ideal for irrigation
