Overview
The problems and solutions associated with sewers and stormwater connections are divided into pipes and associated structures.
Common Pipe Failures
Typical problems encountered with sewer or stormwater pipes include:
- Intrusions
- Encrustation
- Blockages due to tree roots, debris and even concrete
- Cracks/breaks/fractures
- Leaking or broken/displaced joints
- Disused junctions
- Bulges and localised irregularities
- Short ends
- Poorly cut junction re-openings
- Lateral connections blocked
- Failed liners causing blockages
- Pipe lifting holes left unplugged – risk of soil ingress and surface subsidence
- Corrosion
- Leaks
Structures Including Manholes & Culverts
Typical problems encountered with sewer or stormwater related structures include:
- Gas attack of concrete
- Concrete degeneration
- Infiltration gushes
- Groundwater infiltration
- Leaks
- Structural collapse through corrosion
- Cracks
