Application of water saving concept in building water supply and drainage design

: The application of environmentally sound technology and materials in the construction of building water supply and drainage system can increase the utilization of resources, help to improve the energy saving and environmental protection performance of buildings, and truly show the concept of green and sustainable development. The use of energy-saving technology and environmentally friendly materials and the construction of water supply and drainage system with scientific methods and advanced technologies not only improve the performance of water supply and drainage system, but also save a lot of natural resources and energy, thus raising residents' understanding of energy saving and environmental protection, limiting and greatly reducing the damage caused by pollutants discharged into the environment, and can also protect the environment for cities. The sustainable development of green science provides a positive case. This kind of building environmental protection and energy saving technology has been promoted to a more trendy and avantgarde social development direction. On this basis, this report mainly analyzes the importance of energy saving and water saving to water supply and drainage, and puts forward some design ideas and solutions for saving energy and reducing the discharge of water supply and drainage from buildings.
