1, water supply and drainage
Building water supply system can be divided into living water supply system, production water supply system and fire water supply system according to its application. These three kinds of water supply systems are not necessarily separately set up, usually two or three kinds of water supply systems. The building drainage system collects water used by buildings in daily life and industrial production, and drains them out in time. According to the nature of sewage discharged from the system, the internal drainage of buildings can be divided into domestic sewage, domestic sewage, industrial waste water and roofing. Rainwater, sewage (wastewater), industrial waste water and rainwater are set to discharge pipes, known as diversion systems; two or more types of combinations in a pipeline are called combined flow systems; the requirements for different forms according to the water quality conditions and locations are determined after technical and economic comparisons.
