Hola dear.....
Explanation:
Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand. Population, household size, and growth and affluence all affect how much water is used. Factors such as climate change have increased pressures on natural water resources especially in manufacturing and agricultural irrigation.Many US cities have already implemented policies aimed at water conservation, with much success.
The goals of water conservation efforts include:
Ensuring availability of water for future generations where the withdrawal of freshwater from an ecosystem does not exceed its natural replacement rate.
Energy conservation as water pumping, delivery and wastewater treatment facilities consume a significant amount of energy. In some regions of the world over 15% of total electricity consumption is devoted to water management.
Habitat conservation where minimizing human water use helps to preserve freshwater habitats for local wildlife and migrating waterfowl, but also water quality.
The Home Water Works website contains useful information on household water conservation.[22] Contrary to the popular view that the most effective way to save water is to curtail water-using behavior (e.g., by taking shorter showers),[23] experts suggest the most efficient way is replacing toilets and retrofitting washers; as demonstrated by two household end use logging studies in the U.S.[24][25]
Water-saving technology for the home includes:
Low-flow shower heads sometimes called energy-efficient shower heads as they also use less energy
Low-flush toilets, composting toilets and incinerating toilets. Composting toilets have a dramatic impact in the developed world, as conventional Western flush toilets use large volumes of water
Dual flush toilets created by Caroma includes two buttons or handles to flush different levels of water. Dual flush toilets use up to 67% less water than conventional toilets
Faucet aerators, which break water flow into fine droplets to maintain "wetting effectiveness" while using less water. An additional benefit is that they reduce splashing while washing hands and dishes
Raw water flushing where toilets use sea water or non-purified water (i.e. greywater)
Wastewater reuse or recycling systems, allowing:
Reuse of graywater for flushing toilets or watering gardens
Recycling of wastewater through purification at a water treatment plant. See also Wastewater - Reuse
Rainwater harvesting
High-efficiency clothes washers
Weather-based irrigation controllers
Garden hose nozzles that shut off the water when it is not being used, instead of letting a hose run.
Low flow taps in wash basins
Swimming pool covers that reduce evaporation and can warm pool water to reduce water, energy and chemical costs.
Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.

Water Conservation Essay
One of the items people, animals, and our environment cannot live without is water. Water is extremely vital in the everyday life of everyone in the world from everyday life of drinking, washing clothes, animals, grains, cleaning, and so many other uses that eliminating water would eliminate our species as we all depend on the necessity of water. “The water footprint refers to the volumes of water consumption and pollution that are ‘behind’ your daily consumption”. (Network, 2010) If an average American uses approximately 80-100 gallons of water per day then an average American needs to change their ways and contribute to a better water footprint. Water is critical for ecological systems and the health of humans. Animals or plants…show more content…
Examples of products and water are that the “global average water footprint: 15500 litres of water per kg of beef” and the “global average water footprint: 2400 litres of water for one hamburger!” (Network, 2010) Understanding the amount of water our world uses is imperative as there are many consequences to follow globally. The global consequences of using so much water are that globally we are in a water crisis. The demand for water is always a necessity and as the population increases the need for water increases. The lack of safe drinking water and sanitation varies from country to country. “More than one out of six people lack access to safe drinking water, namely 1.1 billion people, and more than two out of six people lack adequate sanitation, namely 2.6 billion people. 2900 children die every day from water-borne diseases”. (Council, 2009) Not only is there a crisis with consumption of water for people but also it is critical that humans reduce the amount of water they use for industrial and agricultural development in order not to affect the aquatic ecosystems and their species. “Water covers almost 70 per cent of the surface of the globe and is the Earth’s most abundant resource. About 97 per cent of the water is the oceans and is too salty for drinking, growing crops, and most other human resources”. (Frederick, 2004) Since globally there is a water crisis, it is important to conserve as much water as possible every day. Not only understanding how
WATER Conservation INTRODUCTION: Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean, generating power, controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it. Water conservation: Refers to reducing the usage of water and recycling of wastewater for different purposes such as ccleaning
