If you do have a serious soaking, you will want to call your insurance company and seek their advice on finding a reliable water damage Austin company.
You should not even think about cleaning things up your self as it is too dangerous. Flood water from whatever source it may come from, has all kinds of harmful stuff in it like raw sewage, chemicals, petroleum residue, bacteria, viruses, and many other nasty things.
You don't really have the equipment, experience or stamina to do everything that is necessary, so get out of the house and stay somewhere else while the water people come in and do their thing.
When they are finished, they will have dried everything out, sterilized the place and you will be able to move back into a nearly brand new environment where you would be hard pressed to know that a water event had even taken place there.
