Water is reused and recycled as natural water processes like a hydrologic cycle. Man-made recycling of water focuses to use treated wastewater. Recycling wastewater may extend to water supplies, reduce disposal and discharge of wastewater, improve the quality of water, and save energy. Water recycling is a major component of the effort of a government to utilize water supplies efficiently. Industries, farms, and cities use recycled water as a substitute for many potable and non-potable uses. Potable use includes drinking water and non-potable uses include industrial processes, crop irrigation, recreational fountains and lakes, groundwater discharge, and wetland habitat restoration, creation, and maintenance.
When you use recycled water for such needs, then you automatically reduce your dependence on surface water. It can reduce groundwater overuse and also minimize wastewater discharges into oceans and rivers. For different water use, different treatment levels are there. The extent of this treatment, tertiary, secondary, or advanced is decided by the primary quality of water, state laws, and its end-use application. If you want to know how to save water, then water recycling is the best option. Various companies are using wastewater through this method. By returning the water to the rivers, it is again used for irrigation.
Water recycling and environmental benefits
Apart from providing a locally-controlled and dependable water supply, water recycling offers incredible environmental benefits. Wildlife and plants depend a lot on adequate water flow to live. The lack of sufficient flow because of urban, agricultural, and industrial reasons can cause the decline of water quality. In many cases, the need for water recycling does not come from the need for water supply but because of the requirement to decrease or eliminate wastewater discharges. Wetland gives multiple benefits that include wildlife habitat, flood diminishment, water quality improvement, and fisheries breeding ground. The streams that have dried can be supplied with water flow to improve the wildlife habitat.
When pollutants are discharged into rivers, oceans; the water bodies are reduced and the pollutants are decreased. Substances that may be pollutants when are discharged to water body can be reused for irrigation, Recycled water contains greater nutrients levels than potable water. When you use recycled water to agriculture, you get additional nutrients and therefore, you do not need to add fertilizers. Extracted water when transported to long distances needs more energy. Recycled water reduces the energy required for pumping water. Even recycled water minimizes the energy required for moving water to long distances. This water is of lower quality and does not need any treatment.
The future of water recycling
Water recycling is successful and effective in creating a reliable water supply. Non-potable reuse is an accepted practice that shall continue to grow. It is expanding to other areas to accommodate the requirements of the growing demand for water supply needs. How to save water is a question asked by many and to address this question, water recycling is the answer. It is a cost-effective and sustainable approach to the treatment of wastewater. Various agencies are reaching out to the public for addressing this growing concern.
