求翻译：不到半个小时，一辆专门消过毒的洒水车到达酒店门前，看着清亮的水哗哗流出来，大家终于松了口气。等酒店蓄水池、水壶统统“喝”饱了，洒水车悄然驶走。是什么意思？

Less than half an hour, a specialized sterile sprinkler reaches the front of the hotel, Huahua look bright in the water flow out, everyone was relieved. All hotels, such as water tanks, water bottles "drink" full, sprinkler quietly drove away.
