10. WATER SUPPLY

The design provides for the following internal water supply systems:

• Drinking water supply system

• Hot water supply

The domestic-fire water supply system is designed to supply water for household drinking needs.

The facility is supplied from the potable water pipeline TsUVS2VK210n (near the clinic). The connection point will be indicated "in place" by the authorized representative of ZPA and PTVA LLP "MAEKazatomoprom."

Tie-in is made by pipeline DN = 50 mm through stripping gate valve DN = 50 mm, RN = 16 (25).

The maximum amount of drinking water consumed per day is 3.5m3. all sections of the connected pipeline of the outer gasket to the point of tie-in to the pipeline have thermal insulation to prevent defrosting in winter.

Hot water supply designed to supply hot water to household needs. Preparation of hot water for household needs is carried out in electric water heater PEVN 2205020.

To prepare hot water, water is supplied from the host-drinking water supply system. The hot water supply network is designed from galvanized water-gas pipes with a diameter of 15; 25mm GOST 326275, are laid open on the walls of the building and painted with oil paint 2 times in the tone of the room.

At the boundary of operational responsibility and balance sheet belonging defined in the energy consumption contract, a heat-insulated metering unit is equipped in accordance with the Rules.

The metering device shall be installed under the control of the State auditor of "MAEKKazatomprom" LLP and in the presence of the authorized representative of ZPDiPTVS with the preparation of a bilateral Act in the established form. The building has a designed water reserve tank with a capacity of 2.0 m3 for watering green spaces.

Sewerage

A household sewage system has been designed in the building.

Waste water discharge from the building bathroom is designed to the external existing sewage pit.

Domestic sewerage networks are accepted from cast-iron sewerage pipes with a diameter of 50100mm according to GOST 6942.380, laid in the floor and above the floor of the building.

Organizational considerations
