Internal water supply

Selection of building water supply scheme

Internal water supply is a system of pipelines and devices that provides cold water supply to sanitary devices and fire cranes, serving the building and having a common water measuring device.

Internal water supply system consists of inlet, water metering unit, main line, risers, pipelines to water discharge devices and valves .

The project provides for the construction of a drinking water supply system. According to item 6.5 [2], a fire-fighting water supply system is not provided in a 5-storey residential building. The quality of cold water supplied shall comply with GOST 287482 *. According to item 9.1 [2], the diagram of the internal water supply network is accepted as dead end with lower wiring, the number of inputs to the building is 1 .

The main line is laid under the floor of the first floor at a distance of 20 cm. Pipelines are laid open along the walls, fixed with detachable clamps. Access to the instruments is open at a distance of 30 cm from the floor.

2.1. Select a channelization scheme

The risers are placed in the bathrooms in such a way that the length of the branch pipelines is the shortest. From sanitary devices to the risers, branch lines are traced from pipes with a diameter of 50 mm (wash, bath, wash basin) and 100 mm (from the toilet bowl). For residential buildings, floor laying of pipes is used. Risers extend above the roof by 0.5 m. The exhaust part of the sewer riser has the same diameter as the riser. Several risers are combined into a prefabricated pipeline and connected to the yard sewage system using exhaust.
