From this thread on shallow wells I have decided that I should build an insulated pump house. Here are some pictures of a design I came up with. Unfortunately I couldn't get the program to show you the framing of the box. What do you think? This would be located in zone 5, Michigan. We have a solar for electricity and we are offgrid. Here are the specs: - Top to bottom, without the hinged "roof" is 6 ft tall - 4 ft wide - Marine grade plywood over treated 2x4's - Black poly plastic covering the plywood sides - Hinged steel roof, also framed with treated 2x4's - Heavily insulated with rigid foam board My plan was to buy it 3 ft in the ground with 3ft of the pump house above the surface. The diagrams show the shelf that holds the pump and pressure tank at the 3ft level. I will need to frame the shelf to support the weight of the pressure tank adequately. I was also planning to backfill around exposed 3 ft of the pump house with dirt and river stone to help insulate the box above the ground. Thoughts? I was also planning to wrap the pipes with the electrical warming "tape" that would be controlled via a thermostat. What do you think?
