7.4      Sensitivity of water supply pipe crossing
Extending from an easement at the end of Liane Drive are four water supply pipes which span the
main channel and project from the creek embankments approximately 1.5m above the creek bed.
The elevations and diameters of each pipe differ slightly with the largest pipe also including metal
frame presumably to prevent people walking across the pipe. Refer to Image 5-2 and Image 5-3.
