4 Water supply
4.1 Water quantity, water quality, water pressure
The designed water supply should be determined based on the following water use: 4.1.1.1
Domestic water:
Production water;
Firefighting water:
Water for flushing platforms and equipment:
Unforeseen water use and water loss in the pipe network. 4.1.2 The domestic water quota and hourly variation coefficient can be determined according to the provisions of Table 4.1.2. When the actual water consumption is significantly different from that specified in Table 4.1.2, the water consumption quota may be appropriately increased or decreased according to the water consumption statistics after approval by the design approval department. Water consumption name
Drinking water for housing
Drinking water for non-housing
