Assuming that the power outage is not due to something that will contaminate rural wells these are some good ways to get water from exisiting wells.
Below are several cheap solutions to make use of existing wells.
Homemade well bucket: The benefits are that it is lightweight and portable. It requires either being able to lift approximately 40 lbs. or a pulley
system to assist with the lifting. Using a smaller diameter pipe will result in less water per haul but it will go down beside existing plumbing.
Using a bigger diameter pipe will result in about five gallons per haul but usually requires that the existing plumbing be removed from the well.
Simplistic hand pump: This can be left in the well and will work alongside of the existing plumbing. Not portable as the bucket is but infinitely more
useful. It's a lot of work and you may want to craft a seesaw device to assist with the pumping.

Water storage or hauling. A good way to store water is by using the potable water tanks designed for travel trailers. You can often obtain them fairly
cheaply at a salvage yard that typically carries wrecked campers and travel trailers. Make sure to inspect it thoroughly before you purchase it. Mount
it to a small trailer for carrying water from the source to your location.
