Cleaning Methods

cleaning of pipes and ducts for both pressure and gravity networks.

Application
Cleaning is applicable to Gas, Water, Sewer/Drainage/Culvert pipes and may be used where cable ducting becomes contaminated due to inflows from outside sources. Cleaning can be achieved over all diameters of pipe irrespective of soil types.
Limitations – The main limiting factor for pipe cleaning may be the length of pipe requiring cleaning at any one time dependent on the type of cleaning system of the technology being used. Access for the equipment may also be problematic given the need for vehicle access and access to a water source, again dependent on the type of equipment used.

Benefits
Cleaning is the most basic of rehabilitation methods in trenchless technology. Simply cleaning a pipeline effectively can reinstate its specified operations requirements without recourse to other most costly and challenging renovation options. It can also be achieved usually with minimum disruption to services and the local community as well as minimal impact on the environment provided the works are undertaken with the collection and correct disposal of waste as a priority.
