Water conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh waterto protect the hydrosphereand to meet the current and future human demand thus avoiding water scarcity. 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 essay on soil conservation irrigation.

Water conservation programs involved in social solutions are typically initiated at the local level, by either municipal water utilities or regional governments. Common strategies include public outreach campaigns, [6] tiered water rates charging progressively higher prices as water use increasesor restrictions on outdoor water use such as lawn watering and car washing.

One of the strategies in water conservation is rain water harvesting. Many people in many countries keep clean containers so they can boil it and drink it, essay on soil conservation, which is useful to supply water to the needy. Another strategy in water conservation is protecting groundwater resources. When precipitation occurs, some infiltrates the soil and goes underground.

An additional strategy to water conservation is practicing sustainable methods of utilizing groundwater resources. A fundamental component to water conservation strategy is communication and education outreach of different water programs.

One fundamental conservation goal is universal water metering. The prevalence of residential water metering varies significantly worldwide. Water metering would benefit society, in the long run, it is proven that water metering increases the efficiency of the entire water system, as well as help unnecessary expenses for individuals for years to come.

One would be unable to waste water unless they are willing to pay the extra charges, this way the water department would be able to monitor water usage by the public, domestic and manufacturing services. Conservation advocates have urged removal of all subsidies to force farmers to grow more water-efficient crops and adopt less wasteful irrigation techniques. New technology poses a few new options for consumers, features such as full flush and half flush when using a toilet are trying to make a difference in water consumption and waste.

Earthships often use such a setup, essay on soil conservation. Also available are modern shower heads that help reduce wasting water: Old shower heads are said to use gallons per minute, while new fixtures available use 2. Such a setup called a " water recycling shower " has also been employed at the VIRTUe LINQ house. Besides recycling water, it also reuses the heat of the water which would otherwise be lost. Contrary to the popular view that the most effective way to save water is to curtail water-using behavior essay on soil conservation. Smart water meters are also a promising technology for reducing household water usage.

A study conducted in Valencia, Spain shows the potential that smart meter-based water consumption feedback has for conserving water in households. The findings showed that households that were equipped with smart water meters increased their water savings. This technology works to show people how much water they were using in their household, suggest essay on soil conservation they can reduce water usage, and incentivize water savings with physical rewards.

Many water-saving devices such as low-flush toilets that are useful in homes can also be useful for business water saving. Other water-saving technology for essay on soil conservation includes:. Water is a very important part in irrigation. Plants always take a lot of ground water thus ground water should be replenished. For crop irrigation, optimal water efficiency means minimizing losses due to evaporationrunoff or subsurface drainage while maximizing production, essay on soil conservation.

Flood irrigationthe oldest and most common type, is often very uneven in distribution, as parts of a field may receive excess water in order to deliver sufficient quantities to other parts. Overhead irrigationusing center-pivot or lateral-moving sprinklers, has the potential for a much more equal and controlled distribution pattern.

Drip irrigation is the most expensive and least-used type, but offers the ability to deliver water to plant roots with minimal losses, essay on soil conservation.

However, drip irrigation is increasingly affordable, especially for the home gardener and in light of rising water rates.

Using drip irrigation methods can save up to 30, gallons of water per year when replacing irrigation systems that spray in all directions. As changing irrigation systems can be a costly undertaking, essay on soil conservation, conservation efforts often concentrate on maximizing the efficiency of the existing system.

This may include chiselling compacted soils, creating furrow dikes to prevent runoff, and using soil moisture and rainfall sensors to optimize irrigation schedules, essay on soil conservation. The UNEP Green Economy Report notes that "[i]mproved soil organic matter from the use of green manures, mulching, and recycling of crop residues and animal manure increases the water essay on soil conservation capacity of soils and their ability to absorb water during torrential rains", [27] which is a way to optimize the use of rainfall and irrigation during dry periods in the season.

As seen in China, plastic mulch also has the potential to conserve water in agricultural practices. The "mulch" is really a thin sheet of plastic that is placed over the soil.

There are holes in the plastic for the plants to grow through. Some essay on soil conservation have shown that plastic mulch conserves water by reducing the evaporation of soil moisture, however, there haven't been enough applied studies to determine the total water savings that this practice may bring about. Water shortage has become an increasingly difficult problem to manage. The imbalance between supply and demand, along with persisting issues such as climate change and population growthhas made water reuse a necessary method for conserving water.

Seawater desalination requires more energy than the desalination of fresh water. Despite this, many seawater desalination plants have been built in response to water shortages around the world.

This makes it necessary to evaluate the impacts of seawater desalination and to find ways to improve desalination technology. Current research involves the use of experiments to determine the most effective and least energy intensive methods of desalination. Sand filtration is another method used to treat water. Recent studies show that sand filtration needs further improvements, but it is approaching optimization with its effectiveness at removing pathogens from water. The removal of pathogens from recycled water is of high priority because wastewater always contains pathogens capable of infecting humans.

The levels of pathogenic viruses have to be reduced to a certain level in order for recycled water to not pose essay on soil conservation threat to human populations. Further research is necessary to determine more accurate methods of assessing the level of pathogenic viruses in treated wastewater.

Wasting of water is essay on soil conservation flip side of water conservation and, in household applications, it means causing or permitting discharge of water without any practical purpose.

Inefficient water use is also considered wasteful. By EPA estimate, household leaks in the US can waste approximately billion gallons 3. However, definition of water waste is often given in local drought emergency ordinances. Water utilities and other media sources often provide listings of essay on soil conservation water-use practices and prohibitions of wasteful uses. Examples include utilities in San Antonio, Texas, essay on soil conservation.

Strictly speaking, water that is discharged into the sewer, or directly to the environment is not wasted or lost. It remains within the hydrologic cycle and returns to the land surface and surface water bodies as precipitation. However, in many cases, the source of the water is at a significant distance from the return point and may be in a different catchment. The separation between extraction point and return point can represent significant environmental degradation in the watercourse and riparian strip.

What is "wasted" is the community's supply of water that was captured, stored, transported and treated to drinking quality standards. Efficient use of water saves the expense of water supply provision and leaves more fresh water in lakes, rivers and aquifers for other users and also for supporting ecosystems.

A concept that is closely related to water wasting is "water-use efficiency. Technical efficiency derives from engineering practice where it is typically used to describe the ratio of output to input and is useful in comparing various products and processes. Urinals are more efficient than toilet stalls in public restrooms for men or boys in situations where the user only needs to urinate; and although this is a natural function, urinals offer considerably less privacy.

The technical efficiency concept is not useful in making decisions of investing money or resources in water conservation measures unless the inputs and outputs are measured in value terms.

This expression of efficiency is referred to as economic efficiency and is incorporated into the concept of water conservation.
