Restoring Water Quality with Trenchless Air Pigging
McBreen Enviro UK recently completed an air pigging project to clean approximately 6km of water pipework at a site in the South East of England.
The network had been experiencing reduced flow and poor water quality due to a gradual buildup of sediment within the pipework.
Objectives
- Clean 6km of pipework sized 3″, 4″and 6″
- Restore water quality across the network
- Complete cleaning within a 10-day working period
- Minimise disruption to ongoing site operations
- Coordinate access to approximately 40 hydrants and 46 sluice valves
Works Completed
The project involved air pigging and scouring of the pipework using compressed air and water to dislodge and remove sediment and internal deposits.
Cleaning was scheduled to target three 200m sections per day, progressing efficiently through the network.
Access to approximately 40 hydrants and 46 sluice valves was carefully managed to facilitate smooth operation throughout the works.
The trenchless method eliminated the need for excavation, allowing site activities to continue uninterrupted.
