My brother has some in-laws that used to have a well drilling business. At their deer camp they have a 30 or so foot deep well that is cased with a 3″ pipe. They have a long skinny “bucket” that fits within the casing and is lowered by a rope down to the water. It is about 2 1/2 feet long and hold about a gallon of water. I wouldn’t want to have to fill a bath tub with it but it is an alternative to a pump in the event it gets damaged.
This is what they look like.
