For this project, we unblocked a pipe that was fully obstructed by calcium
“If we had the budget we would just keep doing this high pressure work for the next 6 months to remove all of the calcium” Sewer Maintenance Director
After removing calcite that lined the full length of the pipe, a full obstructed maintenance hole access was discovered at the end of the pipe.
We were able to open an access to the maintenance hole and clear the pipe end and invert.
The video is sped up to reduce viewing time; actual time working is about 11 minutes. It took about an hour to clear the entire pipe end and invert of any obstruction.
- Obstruction Type Calcite
- Pipe Type 8" VCP
- Year 2019
