School of Municipal and Environmental Engineering, Jilin Institute of Architecture and Civil Engineering, Changchun, 2.

Changchun, Changchun, Abstract—According to the present situation of building water supply and drainage, analyzing the watersaving techniques of building water supply and drainage to achieve effective utilization of water resource. The watersaving techniques mainly include reasonably limiting the pressure of water distribution points and avoiding overpressure flow。 perfecting hot water supply system and reducing ineffectual cold water。 promoting the utilization of highquality pipe and valve。 water conservation。s livelihood but also has bee a major constraining factor that preventing socioeconomic sustainable development. Therefore, we should focus on watersaving. Construction watersaving is system engineering. Except for formulating relevant laws and regulations related to watersaving, strengthening daily management and public education, using price leverage to promote water saving, in addition effective technical measures should be taken to ensure the implementation of construction watersaving thoroughly [1] . II. REASONABLE LIMIT THE PRESSURE OF WATER DISTRIBUTION POINTS AND AVOID OVERPRESSURE FLOW In article of Code for Design of Building of Water Supply and Drainage, domestic water supply system of highrise building should be vertical division. The hydrostatic pressure of residential water distribution points is less than MPa, while office building’s is less than MPa. In special circumstances the hydrostatic pressure is less than MPa。 Automation9780769542867/10 $ 169。 have good running characteristics and have obvious effects on throttling and sound absorbing, which is widely used in the new buildings. However, the price of reducing valve is expensive, so it should be used after doing an economic parison in poor and backward areas. Proportional valve has simple structure and reasonable price which is remended to use. Compared with reducing valve, depression orifice plate’s system is fairly simple, and has less investment as well as convenient management, but depression orifice plate can only reduce dynamic pressure but not hydrostatic pressure, and the downstream pressure is always changing with the upstream pressure and flow rate. So it only can be used under less demand on water supply pressure. III. PERFECT HOT WATER SUPPLY SYSTEM AND REDUCE INEFFECTUAL COLD WATER With the improvement of people39。s Ministry of Construction and the other four ministries jointly issued a document, the document required that the cold galvanized steel pipe was banned used as the water supply pipes of newlybuilt residences in national urban since June 1st, 2020. Based on the local conditions, the hot galvanized steel pipe is gradually prohibited to use and the latemodel pipe is promoted to use. In the construction’s water supply system, plastic pipes mainly consist of low plastic rigid polyvinyl chloride pipe (PVCU), chlorinated polyvinyl chloride pipe (PVCC), highdensity polyethylene pipe (HDPE), crosslinked polyethylene pipe (PE
