To support the development and delivery of a safe and efficient suite of processes, tools and techniques to replace gas mains that significantly reduces the need for the excavation and reinstatement element of existing processes and thereby significantly reduce the costs and customer and stakeholder inconvenience and disruption. This 6" trial will provide a proof of concept for future trials on PRISM (Pipe replacement in situ manufacturing) technique to expedite commissioning of projects correctly targeted at accelerating the delivery of a commercial solution Satisfactory evidence to support the PRISM technique and results that enable us to continue to the 12" trial.

Current methods of replacing gas distribution mains are costly and disruptive to customers and road users. This PRISM initiative seeks to determine a method of achieving the outputs of mains replacement or Re-habilitation with increased customer satisfaction and whilst being quicker and cheaper than current methods. The renewal of mains within a street could be possible via one excavation at each end of the street; this would result in reduced cost and effort, improved safety, environmental benefits through reduced waste to landfill and reduced customer and third party disruption, leading to improved customer satisfaction. This project will build on recent work outside of the NIA and has brought together suitable project partners and delivered proof of concept method of applying a polymer to inside of pipes with potential to satisfy gas industry requirement. Other projects have been undertaken over the past 10 years. The most successful of being project FORGE; a scheme managed by both National Grid and Balfour Beatty. FORGE developed a process to rehabilitate gas mains through a replacement/re-habilitation technology adopted by the water sectors. In 2011 a project for gas mains, 3-6" was undertaken in the Leeds area. This project is to review those achievements and identify a strategic and practical approach to delivering a working solution.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
