Description

In the course work, the systems of internal water supply, internal sewerage and internal drainage are designed. The connection of a residential seven-storey building to city networks is projected, all bindings and marks of systems are shown. Connection of the water supply is carried out through the CTP where booster pumps are installed. Household sewerage is connected to the yard network connected to the city sewerage. According to the estimated depth of laying and elevations of the surface of the earth, the profile of the yard sewerage network is being built. Storm sewers bring water to the scaffolding near the building. The explanatory note contains all the calculations performed in the design of systems, and the specification of the equipment.
