Objectives To trial in an underground environment the PRISM system developed as far as practicable. To develop and laboratory test mains end connection and service connection solutions. A demonstration of the PRISM system in a realistic dead main environment. The technologies demonstrated pass all independent testingA selection of service and mains end solutions to trial. A draft "G23" document that highlights areas that will need development to proceed to live trials.
Abstract Current methods of replacing gas distribution mains are costly and disruptive to customers and road users. This initiative seeks to determine a method of achieving the outputs of mains replacement more efficiently. Utilising PRISM, the renewal of mains within a street could be possible via an excavation at each end of the street. This would result in a reduction in 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 both under and outside of the NIA, and has brought together suitable project partners to develop a method of applying a resin to the inside of cast iron mains pipes suitable for a fully structural solution with potential to satisfy gas industry requirement. This project will trial the PRISM system developed so far in an underground dead main environment, and further develop solution for connecting the pipe to services and interconnecting mains.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
