Water is very important content. With out water there is no life in earth. We use water in so many ways in our daily life. Water is a substance which covers part of the world. It means water is occupying more portion compared to land. But this water is becoming more polluted because of the environmental changes. So it is necessary to conserve the water. It is every one duty to protect the water because everyone uses this water and we the people are making water polluted. Now we may get the doubt how to conserve the water. A few simple changes in home about the water consumption make a vast contribution to water conservation.
As the availability of water becomes more restricted, the costs to both the provider and consumer are increased. In a situation unique to the water supply industry, providers are frequently placed in the position of trying to convince consumers to use less of the commodity that they supply. Most large water providers have departments dedicated to education of the public with regard to conservation. In general, these education efforts have been largely ineffective and conservation of freshwater resources has been best achieved through economic incentives. Water providers frequently provide rebates for those consumers that are willing to change from older technology to newer, such as low-flush toilets and modern washing machines, convert to water efficient landscaping, or otherwise demonstrate lower water usage. Greatest effect has been achieved through tiered pricing. In this pricing structure, users are charged higher rates for each successive unit, or block, of water used. The rate structure penalizes heavy users with greatly increased rates. This technique has been shown to be highly effective in reducing overall usage. In , , for example, an increasing tiered price structure resulted in decreased usage of 26% over a three-year period. Additionally, some communities have implemented the use of water conservation monitors and water waste hotlines to penalize those that continue to waste the resource. Many communities currently limit the type and size of landscaping, the time and nature of outdoor water use, and in extreme cases, have completely banned outdoor water use during crisis periods.
Comprehensive Essay on Water Conservation
Subsurface irrigation is an emerging technology with high water-utilization efficiency. Subsurface irrigation uses a drip-irrigation tubing buried 6 to 8 in (15 to 20 cm) underground, with a spacing of 12 to 24 in (30 to 60 cm) between parallel lines. The tubing contains drip outlets that deliver water and nutrients within the root zone at a desired rate. In addition to water conservation, subsurface irrigation has other advantages that overhead sprinklers do not: minimal over watering, fewer disease and aeration problems, less runoff and erosion, fewer weeds, and better protection from vandalism. However, this system is relatively expensive to install. In , subsurface irrigation has been used on fruit trees, field crops, and lawns, and has achieved water-use savings of about 50%. However, this methodology can, in arid environments, lead to the buildup of soil salinity levels, damaging plants and reducing crop yields. Balancing the water needs of the plant with maintenance of soil quality is an important component of water conservation measures. Technologically advanced irrigation systems now incorporate climate-based controls. These systems utilize meteorological information to determine the need for irrigation and modify the length and duration of irrigation to match the plants requirements. Though these systems are currently used primarily on large-scale applications, development of economical models for the small-scale user is underway.
