Water supply and drainage science and engineering generally refer to municipal water supply systems, drainage systems (municipal water supply and drainage and building water supply and drainage). Water supply and drainage engineering is researched to solve the problem of social circulation of water. "water supply": a modern water supply plant extracts natural water from rivers and lakes every day, purifies the water into tap water meeting the standards of production and domestic water by a series of physical and chemical means, and then delivers the tap water to thousands of households through a city water network of Tongtong and Ba Da. The method comprises the following steps: an advanced sewage treatment plant intensively treats sewage and wastewater which are produced and used in life, and then discharges the sewage and the wastewater into rivers and lakes cleanly.

The water supply and drainage pipeline can be subjected to high water pressure during working, water seepage is easily caused at the joint of the water supply and drainage pipeline, and therefore a sealing ring is generally additionally arranged at the joint of the water supply and drainage pipeline to improve the sealing performance.
