Various high school grades of highrise residential, multilayer, various forms of construction for people, villa, improve the living environment of housing purchase provides various options. When people buy houses in the house, besides attention location, layout, usable floor area, also for residential substandard equipment is concerned. Drainage system as the residence is an important part of the equipment, the rational design of the future, will be for residents of daily use and maintenance of influence.For building drainage design, textbooks and relevant specification already speak quite on the detailed engineering design experience, and talk about some of the characteristics of residential design.1 Building water supply Without the negative frequency water technologies Without the negative frequency supply equipment in recent years is a new water pressurizing equipment, equipment and effectively solved the municipal water supply pipe pressure, can solve the problem of insufficient traditional ways of water pollution, and secondary water can make full use of municipal water supply network, saving more widely used, currently. In municipal water under the condition of insufficient pressure from the local water supply, if can agree that, in the design process of the equipment can be used. MeterGB 500152003 architectural water drainage design specification regulation: the individual housing is relatively concentrated water meter, and should be set in the outdoors, In the water of indoor, appropriate USES longdistance water meter or IC card intellectualized meter. In the past, the design of residential water meter standing in residential kitchen, toilet water, as a household with chunks meter, causing inconvenience to fee, At the same time, the household metering also disrupt the inhabitants of normal life. As residents and safety of illicit close sex, suggestion on design should try to make a longdistance water meter, such as in indoor use CiKaShi meter. There are several a meter in a way: 1) or basement, will set metered on setting, every single water supply pipe set set. 2) Each layeron water meter, set on setting. meter in stairwells rest platform. 3) Water supply pipe set, which sets a meter box, each meter box embedded platform will rest on both sides of the wall. 4) Use longdistance water meter, cassette. Water pollution preventionWater can directly affect the user39。s health. GB 500152003 architectural water drainage design specification of water pollution prevention in a detailed regulations but in actual design work that should notice the following aspects, can do better water pollution prevention:1) Can set minimum air gap in the water pipe shall, when the backflow preventer Settings. 2) Residential water flushing toilet as far as possible USES flush. 3)The drinking water tank, pools of water tank, live in water. In residential design, supply the following several conditions are to set up a water tank: up a water tank for hydraulic system of outdoor multilayer residence building indoor required periodically, insufficient pressure tank, set in the water inlet, made for peak when insufficient pressure on water supply water layers above, B. outdoor water supply system pressure often not required, should put indoor water supply pump and joint.2 Building drainage1) In residential area, although not quite, but health utensils to decorate reasonable or not will directly affect the future use of household produces. When decorating a health utensils, should according to toilet shape with local residents used as possible, use convenient, layout is reasonable. Couplet platoon villa, for such highgrade residence, want to consider to use highgrade sanitary appliances luxurious bath and shower room, sauna room, etc, the possibility of reasonable arrangement draining locations. This is the most mon drain location problem, sit implement currently on the market, each manufacturer of more types of products from the position requirement drain wall is different, so sit implement outfall WKT should as far as possible is reasonable, meet residents as required.2) Sewage discharge pipe namely. Now, because of the lower caused by leak
