Introduction

In this course project, it is necessary to calculate and design a cold drinking water supply system combined with a fire water supply, as well as a domestic sewage system for a residential quarter.

When designing the water supply network, we choose the optimal routing of the network, we expect it to pass the flow rate per hour of maximum water consumption. Based on this, we select diameters and speeds in the pipelines, as well as the hydraulic slope of the network and head loss at each design area. Check the network for pressure flow at maximum water consumption. Based on the fact that the mode of water movement in the water supply line, the pressure one selects the material of the pipes and the type of their insulation.

The sewage network is laid taking into account the gravity mode of waste water movement in the headers. To fulfill this condition, we carry out a hydraulic calculation of the network and select the optimal slope and diameter of the pipes when the liquid moves at a non-silting speed.

In the graphical part of the project, we detail the wells of the water supply network, compile a specification, draw longitudinal profiles of all sewage collectors.

Conclusion

As a result of the calculation, the water supply network of the residential quarter was selected and designed.

The domestic drinking water supply system is designed in case of maximum water consumption, and is also checked in case of fire under unfavorable network conditions. Based on these data, the water supply is designed from cast iron pressure pipes with a diameter of 150 mm. The points of intersection of the water pipeline with sewerage and with roads, as well as inputs to the building, are designed from steel pipes with diameters corresponding to the calculation. All shaped parts and fittings were also selected for the water supply system in accordance with GOST requirements.

The sewage yard network is designed taking into account the gravity mode of the liquid (with optimal deepening of the network into the ground) and non-silting speeds from ceramic pipes with a diameter of 150 mm.

It is recommended to discharge waste water from buildings from cast iron sewage pipe with a diameter of 100 mm.
