For people whose water is on, especially if it is down to trickle, gather as much water as you can in pots, jugs, bottles etc. Before we lost ours completely the water had come down to a trickle and the stores are mostly all sold out of water. Gather as much water as you can while you can. If you don't need it you don't need it but if you do, then you will be happy you put some aside. Water is necessary to drink, cook, do dishes etc. If your water is down to a trickle I also suggest boiling it before using it for the above activities. We were prepared. When the the rest of town had no water we had some to spare. If you are completely out of water gonoutsise and gather snow with items mentioned before. U can use a ladle or cup to scoop. Filter it using a coffee filter, screen. Cheesecloth etc. Then boil and it's safe to drink. If you want flush your toilet then gather snow and get at least 1.5 gallons melted in a pot or bucket. Dump it all all at once in the toilet and it will flush. Cannot use a gallon jug dod this method it will not #texaswinterstorm2021
