I Live in Ontartio, Canada and our winters get cold here. We are building a new house on our 32 acre property and just recently had our well drilled. I am designing a pump house now and need some help.
I am putting in a simple pump and the whole system will run off of a small solar system. The pump house will be 10'x10' (max size that I do not need a permit for) I am going to put a pitless adapter on the well at around 5 feet. I am thinking the pit of the well will be around 6 feet deep, and be approximately 5'x5'. The whole pump house will be well insulated and there will be a false floor over the pit allowing the shed to be used for other things as well. All of my pressure tank, filters and other such plumbing related systems will be in the pit to help it from freezing in the winter.
I was going to pour a concrete floor, and do a cinder block wall up to the level of the ground 6 ' up, and then build the pump house as 2x4 construction. I had a thought of putting infloor tubes embedded in the concrete and connecting it to the return line from my barn to my outdoor furnace to put a little heat in the building. The heat on the return line will not be allot as it has already run through the barn, but would still have a bit of heat in it that could keep the pump house above freezing.
My question is about the floor in the pit. I was going to do concrete but I wonder if I should just do a footing for the pit walls and use gravel as the floor to allow any water to drain. The ground is mostly sand where I live so has great drainage. The water coming from the well is pretty cold (around 50f) so in the summer the pipes and tanks will sweat allot and I feel without drainage it will collect on the concrete.
What would other suggest? Does this seem logical. Is a 5x5x6 pit large enough to hold all plumbing and possible batteries for the solar system?
