The design of water supply and drainage systems not only needs to meet the requirements of efficient operation of water supply and drainage networks

but also should be comprehensively grasped from the dimensions of system energy conservation and consumption reduction as well as intelligent control. Based on an overview of the energy-saving optimization design of the water supply and drainage system in intelligent residential communities

this paper expounds the impact of the energy-saving optimization design of the water supply and drainage system on intelligent residential communities and clarifies the specific measures for the energy-saving optimization design of the water supply and drainage system in intelligent residential communities. Research shows that the building water supply and drainage system plays a crucial role during the operation stage of buildings. By adjusting and improving relevant design schemes and deeply integrating energy-saving design concepts

the operational efficiency of smart residential communities can be further demonstrated

and the total energy consumption of residential projects can be maintained at a low level. This will respond to the policy orientation of building energy conservation and green development

and continuously continue to the high-quality development of the construction industry.
