At present, people's requirements for construction projects are no longer limited to appearance, and their demands for buildings are constantly increasing, including quality, performance, comfort, and so on. Therefore, relevant departments need to strengthen the design of water supply and drainage engineering in the process of building engineering design, and effectively solve the problems existing in the project, so as to ensure the quality of drainage engineering and improve the quality of building engineering.

As an important component of water supply and drainage, the quality of building water supply and drainage directly affects all aspects of our daily life. Strengthening the control of building water supply and drainage quality, eliminating engineering quality defects, and ensuring the vital interests of the people are of great significance. In order to improve the quality of building water supply and drainage engineering, it is necessary to comprehensively and systematically control all aspects of the project from design, construction to final acceptance. Quality control must be strictly controlled in the design, construction, supervision and other management work of building water supply and drainage, and potential safety hazards must be eliminated to the greatest extent possible to ensure the quality and safety of the building project.
