建筑给排水工程设计（Building water supply and drainage engineering design） Building water supply and drainage engineering design In recent years, with the rapid development of national economy and city of our country to accelerate the process of building water supply and drainage rapidly, but there are many problems, such as the pipeline installation does not meet specifications, quality standards, waste etc.. In order to promote the healthy development of water quality, energy saving and water quality improvement, it is necessary to pay attention to these aspects in the process of design. Keywords water saving; energy saving; water quality; reclaimed water reuse; I. The present situation of construction water supply and drainage engineering in China (I) building water supply In our country the city water supply, insufficient water supply capacity in some city, residential and public buildings in city development lags behind the development of water, coupled with the decline in pipeline aging, bearing capacity, many city high-rise buildings need not only boost supply, half of multi-storey buildings can not meet the water requirements, so that our two pressurized equipment widely used, boosting facilities as a proportion of building water supply device in the fastest developing. The common supercharging facilities in our country are water pump, pneumatic water supply equipment and frequency control water supply equipment. The latter two technologies have been mature. At the same time, the water storage tank which is arranged on the roof is a common water storage device, but because of its two serious pollution, the water tank began to develop in a diversified way. A novel water tank from the material is galvanized, enamel, composite steel plate, coating, glass steel and stainless steel water tank, and the water contact surface is not easy to rust, no pollution to water, and reduce the structural weight, solve the problem of inconvenient construction etc.. In addition to these,
