Abstract: This design is 22 residences building water supply of engineering design, mainly including building water supply system, construction drainage system, building fire system, building hot water system. Building water supply system using zoning water supply, one to 4 layer for low area by the municipal water supply pipe directly; Five layers to 13 layer for central, 14 to 22 layer for high layer area, with water pump water tank joint water supply.  Building drainage system: toilet USES corrupt, waste water should be made, the kitchen used wastewater discharge alone, ground floor separate drainage, toilet of sewage treatment by the septic tank back into the municipal drainage pipelines, kitchen and toilet of wastewater straight into municipal drainage pipelines, waste water drainage stand pipe set out only top ventilation stand pipe, water drainage stand pipe set ventilation stand pipe, for double the stand pipe drainage system. The plastic pipe pipe. Building fire system mainly adopts laboratory fire hydrant system, fire 10 min fire water consumption early by fire water tank roof supply, fire protection water tank of water from the fire by fire pump pool extraction; After 10 min fire start fire pump, water from the fire hydrant use for pool, pool of effective volume of 304 cubic meters. The basement set automatic sprinkler system. Fire hydrant system and automatic sprinkler system is using steel tube. Building hot water system USES open type mechanical circulation system, a division system of hot water with cold water system; The focus on hot water supply, heat source from the municipal HTM pipeline network (0.20 MPa), water heater municipal pipeline network under the direct water supply, water heater central and high by high water tank water supply.
