As a result, Continue to have a large living area to be developed.

In this paper, a large residential area project as a reference, only The design ideas and process of domestic water supply system plan are introduced, which provide the basis for subsequent water supply system and water supply pipe deepening design, and provide references for water supply and drainage design of related projects.
