Objectives	The overall aim of this project, building on the CIPP for GD mains project, is to demonstrate that CIPP is fit-for-purpose as a permanent repair and replacement technique for gas service pipes.The cured-in-place pipe (CIPP) technique is a method whereby a host pipe is lined with a flexible tube which is impregnated with a thermosetting resin; this produces a tough pipe-in- pipe replacement solution after resin cure. The resin may be cured by the use of heat or UV light. The technique was developed in the early-1970s and is now used extensively throughout the world, with at least 70,000 km installed to date in adjoining sectors. An advantage of the technique is a smaller site footprint and less excavation and local disruption compared with conventional techniques. The UK gas sector is undertaking a major replacement programme of ferrous mains to reduce the risk of leakage and mains breaks. To achieve the mains renewal target within the current RIIO-GD1 period, it is estimated that 2,000 km of service pipe will also need to be replaced by Cadent.Currently, only plastic polyethylene (PE) or steel pipes are allowed as permanent replacement solutions. In many cases the CIPP technologies can be less expensive and less disruptive and provide better capacity than standard replacement methods. As such, the gas industry is considering the potential to deliver cost savings and reduce social and environmental disruption through the use of these technologies. Lining technologies are also often more practical, especially in congested urban environments where they have a smaller site footprint and typically a faster installation rate than conventional techniques.The ideal solution would offer a fully structural replacement back to original meter position therefore leading to less re-sited metersCadent will work with the Water Research Council (WRC) to deliver this project in five stages:1. Review and report on currently available CIPP productsThere are many variants of these liner technologies; for CIPP liners the major variables include thermosetting resin type, installation method, curing method, wetting-out procedure and location (factory, on-site), lining with and without reinforcement fibres.A comprehensive desk review will be undertaken to summarise the available liner and end fitting systems. This will include contact with WRCs extensive worldwide industry contacts and web searches.2. Development of a performance specification for CIPP for Services with Cadent Policy teams (and HSE if required)A Performance Specification and Best Practice Guide will be written for CIPP in services technologies. A single performance specification and best practice guide will cover all liner techniques.The Best Practice Guide will include recommendations such as design and installation practice guidance, standard operating procedures (SOP), scheme for assessment of conformity (including quality control) and for example, including a decision tree detailing which technologies are appropriate for specific site situations with accompanying SOP.3. Open call to technology providers, evaluation and selection of liner and fitting to proceed to a further (separate) stage of the projectAn open call “technology challenge? to developers and providers will be made to seek out the best possible solutions to this problem. This will ask technology providers to submit their ideas or existing products which fit the challenge. This approach has been used successfully by other utility sectors where there is a benefit in extending a search beyond known supplies and it is believed there is benefit in this approach here. In addition to the companies identified in the Stage 1 Desk Review the call will go out via technical groups and forums, trade associations and social media.WRc and Cadent will then undertake an assessment of each potential technology put forward. This will take the form of a gap analysis using the Performance Specification. The output from the assessment will be used to provide recommendations to the Steering Committee on which CIPP products should be taken forward.4. Risk assessment and testing framework.WRc will devise an appropriate framework for measuring safety, operational and business risks associated with the deployment of CIPP for services, to enable an objective comparison with the risk profile of standard replacement techniques.5. Development of detailed programme for future stagesBased upon our research review, risk assessment framework and building upon any additional learning gained from GD CIPP, WRc will prepare an updated proposal and detailed work programme for future project stages in consultation with Cadent. The objective of this project is to assess the market for potential products to progress to a future manufacture and testing phase and to assess the viability of utilising CIPP technology as a replacement for small diameter pipes (3/4” to 3”).
Abstract	The UK gas sector is undertaking a major replacement programme of ferrous mains to reduce the risk of leakage and mains breaks. To achieve the mains renewal target within the current RIIO-GD1 period, it is estimated that 2,000 km of service pipe will also need to be replaced by Cadent. Currently, only plastic polyethylene (PE) or steel pipes are allowed as permanent replacement solutions. In many cases the CIPP technologies can be less expensive and less disruptive and provide better capacity than standard replacement methods.
