The watermain shall be protected by the following:

- When crossing under or over the watermain there must be aminimum separation of at least 0.6m between the outsidediameters of the crossing pipes.

- A minimum 5.0m length of pipe shall be centered at the pointof crossing so that the watermain joints will be equidistanceand as far as possible from the sewer or PDC. Crossing mustbe absolute minimum 2.0m from watermain joint.

- All construction methods including excavation and backfillcompaction within 0.6m of existing watermain shall be done byhand.

It 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 bondbreak).
