1996 “STREETWISE” workshop visions to 2021
Body scanner & healthy body analogy Previous Research • Want a healthy body of network infrastructure under our streets • Human body easier as we know where most of the pipes should be • If we find the pipes can we find the failures? • Can we diagnose “illness” and prevent failures? Could we develop smart, self diagnosing pipes? • Can we use “key hole surgery” or in-pipe robotics or “self healing pipes” to keep a healthy network
Issues – assessing condition & life cycle • Corrosion weakens pipes Applied load • What load can a weakened pipe take? • New techniques for Supported on bells sampling & testing? • Defining remaining life cycle? • U.Surrey & Thames Water looking at trunk mains
U. Surrey R&D funded by TW Joint condition may also be an issue. “ Excess movement ” “ Locked & corroded ”
Predicting Failure & Life Remaining Understand interactions between natural & built environment? True soil nature in built areas? Predict corrosion & joint movement? Impact of CC on ground & pipe movement? Impact of traffic loading & other excavation? Predict pipe failure from age, condition, soil, traffic & other factors? Corrosive soils Shrink / swell soils London – Soil Map

The facility will be based within The facility will enable full scale experimental studies under a newly constructed building controlled but fully representative conditions to investigate the providing 600m 2 of space. The damage/deterioration mechanisms and failure of distributed building is located, close to the M1 urban water infrastructure. around 6 miles from the University of Sheffield’s main campus. The key experimental infrastructure will comprise a long hydraulic test cell (45m×6m×5m) in which urban water infrastructure assets (e.g. interconnected water pipes, sewer pipes/chambers, inlet structures) and natural artefacts such as impermeable and permeable catchment surfaces, soil The facility is a component part of the Urban Water activity within layers and voids can be created, with in-situ instrumentation the Laboratory Stream of the UKCRIC program. This internationally to allow for their interactions with the urban water leading, collaborative facility will allow researchers to simulate infrastructure assets to be studied. This full-scale physical, chemical and biological interactions between buried pipe environment will then be subjected to a controlled regime of and associated urban water systems infrastructure, the sub-surface, pipe and surface flows and physical and surrounding soil, and the interactions between surface water, in- chemical loadings and then the performance of the pipe (potable and sewage) flows and groundwater. It will allow representative part of the urban water infrastructure system researchers to develop and “field” test new sensing, inspection, will be monitored. repair and rehabilitation systems for surface and underground urban water systems infrastructure at much lower cost and in a more realistic environment than any other facility in the world. The outputs will deliver new fundamental understanding of the failure and degradation mechanisms of both recently constructed and ageing urban water infrastructure systems. Facility Capabilities Current Progress The facility will be able to generate in-pipe and surface flows of up to 200 l/s and subject pipes to pressure transient shocks of up to 10 bar to create conditions of hydraulic capacity exceedance, pipe bursting and contaminant ingress. Complex cyclic loads will be imposed on the contained soil and pipes, via controlled actuators to simulate surface loads. The test cell will have the ability to examine the role of various repeated and sustained Tank excavated and cast. Design of hydraulic systems completed loading types that cause the failure of a wide range of urban and procured. Estimated operational availability June 2018 water assets.
