Justification and selection of water supply and drainage systems

Water supply system

Based on the water balance, architectural and construction solutions of buildings, its storey, the composition of consumers, it is accepted: drinking water supply system B1, which provides water supply from the city water supply system to each apartment in the volume of 300 l/person ∙ day., B1 is divided into a cold water pipeline supplying 180 l/person ∙ day, with the total water consumption of the region of 300 l/person ∙ day and water supply of hot water, supplying 120 l/person ∙ day, with a total water consumption of 300 l/person ∙ day (only cold water supply is being developed).

In accordance with SNiP 2.04.0185 *, fire-fighting water supply with fire cranes is accepted for buildings above 12 floors, which must supply water in case of fire.

Since the number of floors is 9 according to the task, a joint economic and fire water supply is not provided and is not calculated accordingly.

Water disposal system

Domestic sewage system K1 is used to divert household effluents generated in the apartment.
