Water use efficiency refers to the ratio of water used in directly producing goods and services to the amount of water withdrawn from a source. High water use efficiency means less water is wasted. Improving water use efficiency in urban areas can help meet the increasing demand for water due to population growth and urbanization. Increased efficiency also helps reduce the energy used for water treatment and distribution, reducing the impact on water sources.
Different Water USE effeciencies
Residential Water Use Efficiency Residential water use efficiency is the practice of using water in a way that is sustainable and conserves water. In California, water use efficiency is important for supporting communities, farms, and ecosystems.
Indoor Tips:
- Regularly check for and repair leaks in faucets, toilets, and pipes. Even small leaks can waste significant amounts of water over time.
- Replace old fixtures with WaterSense labeled products, such as low-flow showerheads, faucets, and toilets.
- Use high-efficiency washing machines and dishwashers. Run them only with full loads to maximize water use efficiency.
- Reduce shower time to save water. A 5-minute shower can use up to 25 gallons of water.
- Turn off the tap while brushing teeth, shaving, or washing dishes to conserve water. Outdoor Tips:
- Choose drought-resistant plants and native species that require less water. Implement xeriscaping principles to reduce water use in your garden.
- Install drip irrigation systems and smart controllers that adjust watering schedules based on weather conditions.
- Use mulch around plants to retain soil moisture and reduce evaporation.
- Water your lawn and garden during early morning or late evening to minimize evaporation.
- Install rain barrels to collect and store rainwater for irrigation purposes. | Commercial Water Use Efficiency Commercial water use efficiency is the practice of reducing the amount of water used by businesses, industries and institutions. It can be achieved through water-efficient technologies, process optimization, and equipment upgrades. Benefits of water use efficiency
Water use efficiency legislation In California, AB 1572 bans the use of potable water on non-functional turf on commercial properties. Examples of Water Use efficiency
After upgrading its irrigation system, an office complex in Plano, Texas, reduced its outdoor water use by about 40 percent, saving nearly 12.5 million gallons of water in 2009. These retrofits helped the office complex earn water-efficiency credits toward LEED® Gold certification and saved more than $47,000 in 2009. With these savings, the project paid for itself in less than a year and a half! 2. Reducing water waste in food production Strategies for improving commercial water use efficiency
- Conduct regular water audits to identify areas of excessive water use and potential savings.
- Install water-efficient fixtures in restrooms and kitchens, such as low-flow faucets and toilets.
- Optimize cooling tower operations to reduce water consumption. Use air-cooled systems where feasible.
- Educate employees about water conservation practices and encourage them to report leaks and water waste.
- Implement efficient irrigation systems and select drought-tolerant landscaping around commercial properties.
- Explore opportunities for water recycling and reuse within your operations, such as using graywater for landscaping. |
