Studentship description

The project forms part of a larger ongoing programme of research into large diameter (trunk) water mains and trials of pipe condition assessment technology. The wider goal is to improve the sponsor’s ability to understand the condition of its water network for the purposes of long-term asset management, medium-term investment targeting, and short-term tactical planning and risk mitigation.  Thames Water’s network include ferrous (cast iron, ductile iron, steel) and non-ferrous (asbestos cement, polyvinylchloride, polyethylene, concrete and glass reinforced polymer) pipes. Depending on the material, pipes are joined using methods such as socket and spigot, bolted flange and compression couplings, as well as welding. The project aims to establish how both the material and the jointing systems of the pipeline structure are likely to deteriorate and fail in the future. 

The existing approach to predicting average future performance in non-ferrous trunk mains is to carry out statistical analysis of past failures of assets, grouped by pipe age, material and diameter. Moving on from using backward-looking analysis as a guide to future failures, Thames Water would like to arrive at a better understanding of the deterioration mechanisms and processes of failure for the individual pipe systems making up its network. This should take into account the material assessment as well as considering the water main as a structure, so that the majority of common failure types (including pipe barrel and joint failures) are accounted for. The work presents challenges in identifying those failure mechanisms and being able to model their future trajectory towards eventual failure. It is anticipated combining this approach with the original failure data will allow for better targeting of asset investment and improved confidence in its long term strategy for the network. 

The research engineer will be based at the sponsor’s Water Innovation Centre at Kempton Park Water Treatment Works in south-west London. 

The project will start on the 1st October 2019 and will finish on the 31st September 2023. 

Entry requirements

This project requires a First, Upper Second, or merit at Masters in a physical sciences subject. As this is a multidisciplinary project, applications are welcomed from candidates from a range of backgrounds including statistics, mathematics, computing, science, physics, materials science, civil/mechanical engineering. Additional experience is welcomed, knowledge of pipeline engineering would be an advantage. The successful candidate would need to have a strong ability in maths/statistics and experience of numerical modelling.

Non-native speakers of English will be required to have IELTS 6.5 or above (or equivalent). 


This studentship attracts a stipend of circa approx. £20,000 per annum – all fees will be met separately to that amount. Please see our Centre website for background information: View Website

Applications are now restricted to UK/EU students due to funding limitations.
