my first thought is that it is a spring house , i have seen old timers use block and brick and dig a hole close to a creek and build a box, the water seeps in thru the sand and then thru the cracks in the stone/brick/block and fills up the hole with clean water . make it big enough and put a roof over it to protect it and keep it secure and you have a good source of clean water.
