Introduction

The building of any purpose, as well as facilities for cultural and recreational and industrial, located in sewage areas or having an external local sewage system, are equipped with treatment facilities. Constructed water supply systems of buildings shall provide consumers with water of the specified quality in the required quantity and under the necessary pressure. The cold water supply system, called the internal water supply system, consists of the following devices: water metering unit inlet, mains network, distribution pipelines and pipelines, valves, in some cases, head increasing units. The water supply system can be connected to a centralized water supply system or equipped with devices for obtaining water from local sources. For normal operation of the internal water supply at the entrance to the building, such a head must be created that provides the standard flow to the highest located water discharge device. In this project, the domestic drinking water supply system connected to the centralized water supply system is designed. Domestic sewage system is designed for domestic waste water discharge. Internal sewage systems are equipped with ventilation devices, for cleaning in case of clogging. Waste water is usually drained by gravity into the intraquartal sewage network.

Hydraulic calculation of internal water supply network

The entry to the building is laid perpendicular to its foundation, by the shortest distance.

The horizontal distance in the light between the inlets of the drinking water supply system and the outlets of sewers and drains should be at least 1.5 m.

The main line is laid in the basement, below the ceiling by 4050 cm, along the internal capital wall, with a slope of 0.005 towards the entrance, and in the absence of a basement or technical underground - on the first floor in underground channels together with heating pipelines.

The internal water supply network is usually made of steel water-gas galvanized pipes (as per GOST 326275).

The purpose of hydraulic calculation is to determine the diameters of pipes, head loss in them and the required head to ensure uninterrupted water supply to all consumers in the building.

The calculation is in the following order:

Calculation scheme is drawn up;

The diagram indicates the conditional currents (points of change of water flow), the length of the design sections;

Maximum second water flow rates for the design areas are determined;

Pipe diameters are selected by sections;

Linear head losses in the network by sections are determined;

Total head losses are determined.
