General part

1.1 The basis for the development of the Polyclinic project is NPP grade drawings and a task from a technologist.

1.2 This section of the project is executed in accordance with the applicable codes and regulations.

1.3 Section "Water Supply and Sewerage" is developed in accordance with the following regulatory documents:

- SNiP 2.04.0185 "Internal water supply and sewerage of buildings";

- SNiP 2.04.0284 "Water supply. External networks and structures ";

- SNiP 2.04.0385 "Sewerage. External networks and structures ";

- SanPiN 2.1.3.137503 "Hygienic requirements for accommodation, installation, equipment and operation of hospitals, maternity hospitals and other medical hospitals"

- Manual on design of health care institutions (to SNiP 2.08.0289)

1.4 This section contains the main solutions for water supply and sewerage of the designed Polyclinic building.

Water supply

3.1 Drinking water supply (B1)

3.1.1 The internal water supply network is designed for domestic drinking water supply.

3.1.2 The source of water supply is the existing urban general-purpose water supply networks.

3.1.3 For household and drinking needs, drinking water is required that meets the requirements of SanPiN 2.1.4.107401.

3.1.4 Required head 19.0m.

3.1.5 Internal cold water supply networks are designed from propylene pipes, main pipeline (passing along the basement corridor) from steel water and gas pipes as per GOST 326275 *.

3.1.6 The entry is made together with the heat networks, adopted from steel water-gas galvanized pipes GOST 326275 *.

3.1.7 At the entrance to the building, a water metering unit is installed according to the 5.9011 series, selected to pass the flow rate of water for household and drinking needs .

3.1.8 According to SP 4110195, paragraph 4.3, a FMF50 ferromagnetic filter is installed in the water metering unit.

3.1.9 Heat insulate the main pipeline (passing along the basement) with "Energoflex" insulation.

3.1.10 Perforated steel pipeline (dry pipe) connected to B1 system is laid along the perimeter of sauna room. The holes of the pipe are located at an angle of 2030 °, the irrigation jet should be directed to the side surface of the wall. The diameter of the holes should be 3-5 mm with a pitch of 150200mm. Water for irrigation is supplied by opening a ball crane located at a height of 1 m from the floor in an accessible place in a special box having a corresponding designation.

3.1.11 Cover all steel pipelines with PF113 enamel GOST 92682 * two layers by primer layer GF021 GOST 2512982 *. Before application of anticorrosion coating, clean pipes from scale and rust up to degree 2, provide and degrease according to GOST 9.4022004.

3.1.12 Piping shall be accepted as open in bathrooms and hidden (in boxes, sheeting ceiling) in other rooms.

3.2 Hot water supply (T3)

3.2.1 Hot water supply is carried out from the water heater (see part of CW) operating year-round from the heat networks of the city .

3.2.2 According to item 5.4 of SanPiN 2.1.3.137503, standby hot water supply (in case of emergency disconnection of networks) from electric water heaters is provided:

- storage type Super Glass Ariston SG 80 (V = 80 l, N = 0.112 kW) are installed in a sanatorium, sanbines (showers).

- flow type Ariston Bravo E 3323 UF7 (Q = 24 l/min, N = 3.3 kW) are installed in preoperative, procedural, dressing room, eating room and lore room (procedural).

3.2.3 Required head is 24.0 m.

3.2.4 For water circulation the pump is provided WILOStarZ 20/7 (Q = 0.9 m3/h, H = 5.6 m, N = 0.112 kW).

3.2.5 Towels are installed in rooms equipped with shower nets or baths on the hot water pipeline.

3.2.6 At the lower point of the network T3, T4, a descent is installed - for lowering water from the system, at the higher point - an air duct, for air discharge.

3.2.7 Hot water temperature is provided 60 ° С.

3.2.8 Hot water supply network is adopted from polypropylene pipes.

3.2.9 Heat insulate the main hot water supply pipeline (in the basement) with "Energoflex" insulation.

3.2.10 Pipeline laying is accepted as open in bathrooms and hidden (in boxes, sheet ceiling) in other rooms.

Sewerage

4.1 Domestic sewerage system (K1)

4.1.1 Domestic sewage system is designed to drain effluents from sanitary devices. The network is made of polyethylene sewage pipes according to GOST 2268989.

4.1.2 Waste water is discharged by two outlets:

- waste water from sanitizers of 1-4 floors ;

- waste water of the basement.

Drains are drained by gravity to the existing urban external sewage network.

4.1.3 The issue is accepted from plastic sewage pipes according to GOST 185992001.

4.1.4 Pipeline laying is accepted: open along walls in bathrooms, and hidden in the channel (in the basement) and in boxes, in the basement ceiling (together with water supply pipelines) in corridors and other rooms.
