Water supply and sanitation of a six-storey residential building - coursework

In this course project, it is necessary to design the internal systems of cold water supply and sewerage of a multi-apartment six-storey residential building, as well as to connect the cold water supply to the existing external network, and to divert wastewater from the internal sewerage network to the existing yard network.

A residential building of apartment type is equipped with water supply, sewerage, with a total rate of water consumption of the highest water consumption qutot = 210 l / day.
The distance from the red line to the building is 6 m, the height of the floor is et = 3.0 m; floor thickness – 0.3 m.

The initial data for the design and calculation of the internal water supply and sanitation system are as follows.
Number of floors 6
Rate of water consumption, qn, l/day·person 210
Warranty head, Hg, m 23,1
Diameter of the city water supply, Dv, mm 300
City sewerage meter, DK, mm 300
Basement height, h, m 2,6
Depth of soil freezing, m 1,8

Distance from the red line to the building, l, m6
Elevations, m:
- Ground surface near the building 97.5
- ground floor 98.0
- Tops of the city water pipe 95.1
- Tray in the well of the city sewer 94.0
- the surface of the earth at the sewerage connection point 97.2
