6.3: Structural loads transmitted to water and sewerage network mains
ActewAGL will approve an application for building or landscape works only where water and sewerage network equipment is protected from dynamic or static structural loads transmitted by:
- construction or maintenance equipment (cranes, vehicles, earthmoving equipment, compaction equipment, lifts, scaffolding, etc.)
- proposed structures
- earthworks in excess of as-constructed levels
- stored materials
- any other load-bearing element that may, in the opinion of ActewAGL, cause or have the potential to cause harm to the integrity of the network equipment regardless of whether or not that equipment is inside or outside the property boundaries.
As a guide, ActewAGL will generally approve an application where the bearing for any imposed load (in local Canberra soils) is outside a 45-degree angle measured from the invert of the network main (see illustration below).
Approval is also conditional upon compliance with foundation stability rules.
Alternative conditions may apply to rock or uncommon soils.
Note: ActewAGL will not allow concrete encasement of water or sewerage network pipes to carry loads imposed by structures.
