Details are sketchy but the recent sinking of the cargo ship at Aswan must be the cause. We have been told no water for one or two days not sure when it starts.
My swimming pool will flush the toilets and provide buckets to wash in. I am filling up roof tank which will be good for cooking and there is mineral water. So relatively we are ok but others are not. When you earn 200-300LE a month a 2LE bottle of water is a big chunk.
