One issue that we are working through is the odd sewer system. Our home-site sits about 30ft below the on-site sewer system, so we will obviously need to pump sewage up-hill to the pipe. The main issue is that the pipe on our property is pressurized to 38psi.
Converting pressure in psi to head in feet
h = p 2.31 / SG (3)h = (38psi * 2.31) / 1 (SG of water)
h = head (ft)
p = pressure (psi)
h = 87.78 ft
Tack on another 25' in elevation just to GET to the pipe... and our pump has to be pretty beastly. There may be a couple other options, but we wont really know until we meet with the City next week.
