I'm picky about the water myself and my family drink. I want it to be as close to wild natural water as I can get it. This house is fed by a spring that comes right out of the ground about 300' from the house near a beautiful rock bottom creek. The problem was that the pump was broken, the wiring was really rigged up and the pump was sitting on top of an 5' pile of cinder blocks inside of the spring house. This pile of block closely resembled a critter high rise apartment with many nests on each level with the poop and pee going directly into the water where the pump was fed. I don't know how the people drinking from here survived the many pathogens which must have been present in the water. My Dad had a local well installer replace the pump before we got there and I redid the wiring.
The structure itself consisted of a concrete box poured into the side of the hill with the water entering under the wall on one side. On top was a dilapidated rotten plywood structure with a piece of sheet metal on top. Obviously this all had to go.
Here's me getting all that block and the mechanicals out of the hole. I love this stuff!
Then I dug all the muck out of the bottom of the house in a thunderstorm.
Then I put it all back together in such a way that not even spiders get into it. After flushing the whole system, having the house itself re-plumbed, and installing a UV filter in the house the water tested good at the local municipal water department. Its real good water. It's spring water and I can really notice a difference in how I feel since drinking it exclusively. It also is great for bathing/showering and leaves no soapy film behind.
