Water efficiency


Improving water efficiency involves developing and introducing new water technologies and solutions, implementing new policies and regulations, and changing consumer behaviours. It is important because rapidly growing populations and changing climates put significant pressure on freshwater availability and quality. Ensuring future security of freshwater resources requires new approaches to water management. Water sensitive cities provide water security through efficient use of diverse resources.

Management approaches


Research application

The CRCWSC’s water efficiency research has been applied in the following examples:

  • It was used to identify opportunities for water efficiency at Queens Park Regional Open Space including wicking bed playing fields and smart irrigation systems.
  • The Waterwise Council Program in Western Australia is a partnership that aims to build cooperative working relationships with local governments to improve water efficiency.
  • Water efficiency and alternative water supplies led to Josh’s House achieving a 92% reduction in mains water use compared with the average Perth home.
