Underslab Drainage plumbing & Services entry points (water, electrical)


Original plumbing for reference (‘dial before you dig’)

Existing services that may impact earthworks are minimal.  House stormwater / septic pipes are sufficiently clear of the shed:


A small 300x300mm drainage pit to remove surface water from driveway was added in recent years.  This can be adjusted as needed or left in place.

Earthworks is straightforward without obstructions and involves pushing small rockdrain rocks aside and creating a level pad area 100mm above soil level all around, allowing for easy under slab plumbing at lowest point (= east elevation).
