Cold water supply

2.1 SELECTION OF WATER SUPPLY SYSTEM AND SCHEME

The internal water supply network is designed with one input. The network is designed as a dead end with a dilution pipeline laid along the walls of the first floor. In this building, a break in the supply of cold water is possible, as a result of which the ring of the network is not required.

2.2 SELECTION OF INPUT PLACE

At the plant building at a distance of 11 m from the building there is a network of designed water supply B1, with a diameter of 75 mm, laid from polyethylene pipes.

To connect to this network, a well with a gate valve is installed and an inlet with a diameter of 75 mm is laid from polyethylene pipes.

2.3 PIPING AND VALVES FOR COLD WATER SUPPLY

We accept metal-plastic, steel galvanized and polyethylene pipes. Metal-plastic - supplies to instruments, steel galvanized pipes - risers and lines with a diameter of 25mm or more. Polyethylene pipes - water supply to the building.

Pipeline valves are installed at pressure of 0.6 MPa of valve type. With a diameter of 50 mm or more, we install disk rotary locks. A valve is provided at the base of the riser.

We install shutoff valves: at the entrance to the building; on branches from main lines; at the base of the risers; on branches supplying five water discharge points or more; on supply to flushing tank [2, section 10.5].

At the point of connection of the input, we install a pit with a diameter of 1500 mm, with a valve (gate) device in it to turn off the input. The input is installed with a slope of 0.005 towards the external network.

2.4 WATER METERING UNIT

Immediately behind the outer wall, we install a water metering unit with a bypass line, since in this project we have one input. On bypass line we install sealed gate valve. On each side of the water meter, a straight section of the pipeline is installed, the length of which is determined by the standard for meters. Before and after the water meter we install shutoff valves. Between the counter and the second (in the direction of water movement) valve or gate valve we install a drain valve.

Hot water supply

3.2 HOT WATER PIPELINES AND VALVES

We accept metal-plastic and steel galvanized pipes. Pipeline valves are installed at pressure of 0.6 MPa of valve type. With a diameter of 50 mm or more, install gate valves (gates). At the base of the riser we provide a valve and a drain plug. Shut-off valves up to and including 50 mm in diameter should be used bronze, brass, or made of heat-resistant plastics.

We install shutoff valves: at the entrance to the building; on branches from main lines; at the base of the risers; on branches supplying five water discharge points or more [2, section 10.5].

Check valves are installed on the sections of pipelines supplying water to the group mixers on the circulation pipeline before connecting it to the water heater [2, section 10.16].

Sewerage (internal)

4.1 SEWER SYSTEM SELECTION

The sewerage system is designed for household use - for waste water removal from sanitary and technical devices.

Washbasins, toilets, shower trays and ladders are installed for waste water removal. All sanitary appliances have hydraulic locks. Toilets are equipped with flush tanks.

Waste water is discharged via closed gravity pipelines.

The network is made of plastic pipes with a diameter of 50 and 100 mm. Connection to the riser of branch pipelines is carried out using oblique crosses and tees.

Laying of internal sewerage networks is made, open, risers are laid along the walls of bathrooms and other rooms.

Risers are brought to the roof, to a height of 0.5 m for a pitched roof. Revisions are installed on risers. The network is laid with a slope of 0.02.

Designed 4 outlets with a diameter of 50 and 100 mm. Prefabricated reinforced concrete wells with a diameter of 1 m are installed at the outlets.
