Essay on Save Water for Children and Students
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.

Water conservation can also be advanced by improving other domestic uses of water. One simple conservation practice is to install ultra-low-flush (ULF) toilets and low-flow showerheads in homes and other buildings. A ULF toilet uses only 1.6 gal (6.1 l) per flush, compared to 5 to 7 gal by a standard toilet. Replacing a standard toilet with an ULF saves about 30 to 40 gal (114 to 151 l) of water per day, equivalent to 10,000 to 16,000 gal (37,850 to 60,560 l) per year. More recently, advanced toilets and urinals requiring no water have been developed and are beginning to be utilized on a limited basis.

One of the most important objectives for the water conservation is a widespread installation of metering systems. Distribution of water meters in the private sector is very different in different countries. Recent surveys have shown that in the U.K. only 30% of households use meters to measure their water consumption, In Canada this indicator reaches 61%. Although there are conflicting opinions about the usefulness of the installation of water meters in private homes, according to the U.S. Agency for Environmental Protection, the metering could reduce consumption by between 20 and 40 percent. These metering systems do not only inform consumers about the level of water consumption, but are an excellent tool for the detection and localization of leaks.
