The general scope of this project extends to low pressure pipes in the Tier One RIIO range.
The focus is primarily on domestic type mains renewal schemes where the excavation density is typically highest and the benefits are therefore maximized.
This project will undertake field testing of an end to end solution.
Deliver an end to end field tested, pre-commercialised operational system for 4” applications.
Deliver a prototype demonstration system for 6” applications.
Compelling case to continue to Stage 5
