-
The watermain shall be protected by the following:
When crossing under or over the watermain there must be a
minimum separation of at least 0.6m between the outside
diameters of the crossing pipes.
A minimum 5.0m length of pipe shall be centered at the point
of crossing so that the watermain joints will be equidistance
and as far as possible from the sewer or PDC. Crossing must
be absolute minimum 2.0m from watermain joint.
All construction methods including excavation and backfill
compaction within 0.6m of existing watermain shall be done by
hand.
should be noted that the support structure is to remain in
place until the watermain is fully supported by the reinstated
bedding (i.e, until SMPa unshrinkable fill is cured, provide bond
