- Immediate backfilling resulting in less cleanup and increased safety
- Reduced dewatering and shoring costs in poor ground conditions
- No added labour costs or job hold ups as pits are installed by the pipe laying crew as needed
- Pipe and pits can be ordered together
- Head losses are reduced when compared with square pits, as the circular shape assists in hydraulic efficiency
- Sumps or silt traps are easily obtained by deeper installation then required for drainage purposes
- Most pipes enter the pit radially
- Orientation is simple, allowing for easy alignment to suit the pipelines
- Holes can be punched quickly and where needed in the field
