The Danish Quality Control Scheme for Pipeline
Rehabilitation was founded
Ensuring that contract work performed complies with: • the quality manual of the company
• the declaration of the rehabilitation system in question
The Control Scheme, currently only underground
non-pressure drainage and sewerage networks, comprises: • Renovation by lining with Cured-in-place pipes
• Renovation by lining with Close-fit pipes • Replacement by Pipe bursting

ISO 11295: Definitions
■ rehabilitation
all measures for restoring or upgrading the performance of an existing pipeline system
■ renovation
work incorporating all or part of the original fabric of the pipeline by means of which its current performance is improved
■ replacement
rehabilitation of an existing pipeline system by the installation of a new pipeline system, without incorporating the original fabric
■ technique family
group of renovation techniques which are considered to have common characteristics for standardisation purposes

Pipe bursting
Trenchless renovation is a maturing market
supported by international standards
ISO standards for pipeline renovation available
Renovation is an application in which plastics
have demonstrated their versatility
Challenges different from those of direct-bury pipe
Required testing of products in the installed state
assures quality of the new pipeline
