I live in East Texas. I have a propane tank in my yard and I have a gas heater in my house. I have an electric heat pump ac unit. We have a propane water heater and stove. We also has a wood burning stove with blowers that will heat most of our 2300 sq ft home. We also have a big Diesel generator that we bought after Hurricane Katrina. As prepared as my family tries to be, as a state, we are woefully unprepared for these temperatures. Almost every water supply in our area is down. My local hometown has no more bottled water, milk or bread. I have plenty of quarantine food, but unless I get water from my hot tub or pond, it is going to get bad.
Do you have your own well, it is it coming from town supply?
Got snow, sleet, or ice? Water from creekâboil it. Water for people, or livestock involved also?
Your water heater is a good source of fresh water. Usually in the range of 30-50 gallons.
That could help you get through a few days.
The back of each of your toilets are good for 2-5 gallons I believe it is.
Desperate times call for desperate measures.
If you have snow, you can collect it, melt it, boil it, and expose it to Sunlight for a few minutes to kill bacteria and viruses.
You could take a pass on showers for a few days or simply use a washcloth and very little water to clean up.
You can use a clean new bug spray canister to make a hand pump shower. I take showers on 1.25 gallons of water.
Drinking water and showers, some coffee and looking, I could easily last ten days on 30 gallons.
