Study tests the water for more efficient products

Abstract

Water conservation Traditionally, water consuming products, such as toilets, showers, washing machines, dishwashers, baths and taps have been designed with functionality, aesthetics and cost in mind. Little attention was paid to how much water these items used. However, global concerns such as burgeoning population growth and rapid urbanisation amid increased water scarcity has prompted the realisation that water can no longer be used with reckless abandon, and sparked investigations into ways of using water more appropriately and efficiently. There are many examples of water demand management and water conservation campaigns that have been implemented around the world: the city of Seattle in the US, for example, has reduced its water consumption by 1% each year over the last 23 years despite a 23% increase in its population. In southern Africa, the city of Windhoek has managed to reduce the average consumption from 320 ℓ per person/ day to 220 ℓ per person/day over the last 30 years.
