Lack of water for household use
- A recent ABS Report has identified Australia is one of the driest continents on earth with limited renewable freshwater resources.
- Of the limited rainfall, most soaks into the ground with less than 12% of run-off collected in rivers.
- Of the total water used by households, 96% is supplied by mains water (potable water) and only 4% from rainwater tanks etc.
- As a further example each year the typical Melbourne home uses 270,000 litres of water. That's equal to about 5 average swimming pools.
- In a nation plagued by droughts, limited rainfall and a rapidly expanding population, harvesting water, supplying and the treatment of waste water will continue to drive up the cost of delivering these services.
Domestic water conservation a top priority
- Governments (Federal, State and Local), have recognised the need to manage the nations precious water resources and are offering rebates and incentives to ‘water wise’ consumers.
- State governments in particular are driving change via programs that reward the environmental credentials of a home. Eg. 5 Star (VIC), Basix (NSW) and Water proofing Adelaide (SA)
In addition the
Gold Coast Council has introdced a Gold Coast Water - Waterfuture Master Plan
- Local councils are encouraging the development of new estates which incorporate recycled water systems, rainwater tanks and grey water utilisation.
- New developments designed to embrace these water saving features will deliver a powerful competitive edge for participating developers and builders.
Water usage in the home
- The most efficient way to reduce a household’s mains water usage is to install a constant draw down and constant replenishment system such as Aquasource. That makes the toilet and laundry supply from a rainwater tank the most effective way to achieve a reduction in household mains water.
- If the tank system is used in conjunction with a mains interconnection device such as the Aquasource controller, a more compact tank would suffice as supply security is provided.
- Environmental benefits are derived from smaller systems as they reduce demands for mains water and are highly efficient.
- Against this background Aquasource has developed a unique ‘Rainwater Utilisation System’ designed to reduce a household’s dependence on mains water.
- Aquasource systems allow more appropriate sizing for high-density sites where space is at a premium, but return maximum potential to reduce mains water usage.
- Fitting an Aquasource ‘Rainwater Utilisation System allows households to use rainwater instead of potable water as the primary resource for the toilet and laundry resulting in water conservation and financial savings for the householder.
