1) the accomplishment of a function, task, process, or result with the minimal amount of water feasible;; 2) an indicator of the relationship between the amount of water required for a particular purpose and the amount of water used or delivered. ;

Though the two are often used interchangeably, there is a difference between water conservation and water efficiency. Water efficiency differs from water conservation in that it focuses on reducing waste. A proposition is that the key for efficiency is reducing waste, not restricting use. It also emphasises the influence consumers can have in water efficiency by making small behavioural changes to reduce water wastage and by choosing more water efficient products. Examples of water efficient steps includes fixing leaking taps, taking showers rather than baths, installing displacements devices inside toilet cisterns, and using dishwashers and washing machines with full loads. These are things that fall under the definition of water efficiency, as their purpose is to obtain the desired result or level of service with the least necessary water.

Importance

According to the Second United Nations World Water Development Report, if present levels of consumption continue, two-thirds of the global population will live in areas of water stress by 2025. Increasing human demand for water coupled with the effects of climate change mean that the future of our water supply is not secure. As of now, 2.6 billion people do not have safe drinking water. Added to this, are the changes in climate, population growth and lifestyles. The changes in human lifestyle and activities require more water per capita. This tightens the competition for water amongst agricultural, industrial, and human consumption.

Organisations

In most countries, people have recognized this growing water scarcity problem. Water efficiency, while not yet a major priority in the agendas of governments, has been a growing concern. Global organisations like the World Water Council, the International Water Management Institute, and UNESCO have been promoting water efficiency alongside water conservation.

Waterwise in the UK, the California Urban Water Conservation Council, the savewater! Alliance in Australia, and the WaterBucket website in Canada are some non governmental organisations that promote or support water efficiency at local national levels.
