| **** | **Conditions for using the municipal water supply network as a water source**. When the hotel uses the municipal water supply network for direct water supply, it should be ensured that there are **two** service pipes (or the requirements for a looped network are met), and the municipal water supply pressure and flow rate should meet the firefighting requirements of the fire hydrant at the most unfavorable point. Otherwise, a fire water tank should be provided. |
