Question

paragraph on save water 300 words

Answer 1

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.[1] Many US cities have already implemented policies aimed at water conservation, with much success.[2]

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.[3]

Strategies[edit]

The key activities that benefit water conservation(save water) are as follows :

Any beneficial reduction in water loss, use and waste of resources.Avoiding any damage to water quality.Improving water management practices that reduce the use or enhance the beneficial use of water.[4][5]

One strategy in water conservation is rain water harvesting.[6] Digging ponds, lakes, canals, expanding the water reservoir, and installing rain water catching ducts and filtration systems on homes are different methods of harvesting rain water.[6] Harvested and filtered rain water could be used for toilets, home gardening, lawn irrigation, and small scale agriculture.[6]

Another strategy in water conservation is protecting groundwater resources. When precipitation occurs, some infiltrates the soil and goes underground.[7] Water in this saturation zone is called groundwater.[7] Contamination of groundwater causes the groundwater water supply to not be able to be used as resource of fresh drinking water and the natural regeneration of contaminated groundwater can takes years to replenish.[8] Some examples of potential sources of groundwater contamination include storage tanks, septicsystems, uncontrolled hazardous waste, landfills, atmospheric contaminants, chemicals, and road salts.[8] Contamination of groundwater decreases the replenishment of available freshwater so taking preventative measures by protecting groundwater resources form contamination is an important aspect of water conservation.[6]

An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources.[6] Groundwater flows due to gravity and eventually discharges into streams.[7] Excess pumping of groundwater leads to a decrease in groundwater levels and if continued it can exhaust the resource.[6] Ground and surface waters are connected and overuse of groundwater can reduce and, in extreme examples, diminish the water supply of lakes, rivers, and streams.[8] In coastal regions, over pumping groundwater can increase saltwater intrusion which results in the contamination of groundwater water supply.[8] Sustainable use of groundwater is essential in water conservation.

Answer 2

Answer:

Save water save environment

Water is necessary for life. Water is needed for domestic, agricultural and industrial purposes.

Three-fourth of Earth's surface is covered by water bodies. 97 per cent of this water is present in oceans as salt water and is unfit for human consumption. Fresh water accounts for only about 2.7 per cent. Nearly 70 per cent of this occurs as ice sheets and glaciers n Antarctica and other inaccessible places. Only one per cent of fresh water is available and fit for human use. So it is very important to conserve this precious resource. And yet we are contaminating the existing water resources with sewage, toxic chemicals and other wastes. Increasing population and rapid urbanisation has led to over-use of water resources leading to water pollution and scarcity.

How to save water

•Fix your leaks

•Flush with less

•Turn off tap while brushing

•Bath for short duration

•Install a faucet aerator

Many areas in the western U.S. experience water shortages. At the beginning of 2014, California faced its worst drought in 500 years, according to B. Lynn Ingram, a professor at the University of California, Berkeley. The State Water Project, which supplements the local water supply for several California towns, is completely out of water.
