We have a dilemma on how best to replace UG pool equip. wiring. Residential home on a 8500 sq. ft. lot with a mature landscape. The 35 year old IMC conduit has been compromised and is unsafe. The entire backside of the home is concrete patio where the old conduit is/was. The alternatives seem to be tearing up the concrete or saw-cutting a chase (expensive) or running both PVC for underground and EMT above ground attached to the "2 x 10" mud rail at the bottom of the fence at the back of the property. The fence rail is the only area (in one area) where we can maintain a clearance of more than 5' from the wall of the pool. Underground is impossible back there due to mature trees & shrubs (roots). This conduit would contain 2) 220 volt motor circuits, a 20 GFCI protected pool lighting circuit and equipment ground wire @ 150' long. Pool equip. is on the other side of service equipment, motor circuits increased to #10 THHN. Any other ideas? Stuck!

minimal disturbance of the land at the entrance and exit of the U.G. pipe.

I don't know exactly what you have but if this pool area is a separate structure from the house then it is not code compliant to run 2 circuits as you stated to the area. I would add a pool subpanel and run PVC the entire way.

Take a look at 680.23(F)(3) - in regards to GFCI conductors for pool lighting installed in the same raceway as "other" conductors.
