WATER CONSERVATION

Water conservation refers to reducing use of fresh water, through technological or social methods. The goals of water conservation efforts include: Sustainability - To ensure availability for future generations, the withdrawal of fresh water from an ecosystem should not exceed its natural replacement rate.Energy conservation - Water pumping, delivery and wastewater treatment facilities consume a significant amount of energy. In some regions of the world (for example, California ) over 15% of total electricity consumption is devoted to water management.Habitat conservation - Minimizing human water use helps to preserve fresh water habitats for local wildlife and migrating waterfowl, as well as reducing the need to build new dams and other water diversion infrastructure.

water conservation
n : the conservation of water resources

Noun
1. the conservation of water resources
(hypernym) conservation

The physical control, protection, management, and use of water resources in such a way as to maintain crop, grazing, and forest lands, vegetative cover, wildlife, and wildlife habitat for maximum sustained benefits to people, agriculture, industry, commerce, and other segments of the national economy. Water conservation measures result in a reduction in applied water due to more efficient water use such as the implementation of Best Management Practices (BMP): Urban Water Use, or Efficient Water Management Practices (EWMP): Agricultural Water Use. The extent to which these actions actually create a savings in water supply depends on how they affect new water use and depletion.
