Contaminant Ingress into Distribution systems (CID)
Lead Research Organisation:
University of Sheffield
Department Name: Civil and Structural Engineering
Abstract
The quality of potable water is of vital importance to public health. However, contamination events are observed to occur even in the tiny volume (relative to total supply volume) of the samples collected for regulatory purposes. These events are often unexplained. A possible source of such contamination is pollutant ingress into the distribution system from the surrounding soil and water. Such ingress can occur through the many apertures normally associated with leakage, at times when low or negative pressure conditions occur such as due to hydraulic transients (water hammer).This project will investigate the currently unknown potential for such contaminant ingress into potable water distribution systems by direct measurement utilising a specially developed laboratory facility. Laboratory studies are necessary to address difficulties associated with the short response duration of transient events and the costs, complexity and regulatory unacceptability of field studies. The experimental set up will be full scale and include surrounding ground conditions and a contaminant flow field (for example, an adjacent leaky sewer). Initial studies will investigate the influence of the characteristics of the transients (magnitude, duration etc.) while further studies will investigate the influence of aperture shape, geometry and location.The experiments will provide quantitative evidence of the conditions causing ingress which will be used to develop a new ingress model which, together with existing modelling tools, will enable quantification of the potential for contaminant ingress. The outputs from the new modelling approach will inform improvements to distribution system design, operation and maintenance, management of pollution incidents and ultimately result in improved drinking water quality.The project will be undertaken at the University of Sheffield, with advice and support from Professor Bryan Karney of Toronto University, an international expert in transient analysis and in collaboration with Ecole Polytechnique de Montreal for access to the best currently available relevant field data.

| Description | Contaminant Ingress into Distribution systems (CID) has explored the possibility of drawing pollutants into pressurised water distribution pipes due to dynamic hydraulic conditions. This is directly relevant to drinking water quality and hence of importance to public health and wellbeing. The project has, for the first time, conclusively proven that contaminant ingress can occur. While the dynamic hydraulic conditions required are extreme, they can occur within real water distribution systems. This has been achieved through a programme of sophisticated experimental study using an internationally unique physical testing facility developed at the University of Sheffield. The facility is full scale and representative of real system conditions, in particular the surrounding soil and water. Demonstrations using the facility have, and continue to be, vital to the relevance and impact of the completed and future research. [obj. 1]. The programme of experimental work has allowed systematic quantification of the relative significance of different physical factors including the dynamic conditions, leakage aperture geometry and location, and soil and ground conditions. This has brought unique new understanding of the dominant role of the fill material immediately external to pipes and the importance of considering three dimensional effects in the surrounding ground. [obj. 2] The new understanding resulting from our research is relevant to both ingress and leakage, including improvement to leakage estimation. Considerable added value with major new findings has resulted from research associated with crack opening behaviour under dynamic conditions. This has yielded new information directly relevant to active pressure management strategies. [obj. 3] We have used an active programme of modelling to inform our experimental programme, and have developed practical tools for risk assessment and advanced analytical tools for further research. We have derived and verified an expression that effectively and efficiently quantifies ingress and leakage volumes. This expression considers the three dimensional effects of soil/ground external to a pipe and is in a form that may readily be applied in current water network modelling software used in practice and research. We have produced and verified novel computation fluid dynamic models which are also relevant to both ingress and leakage. [obj. 5 & 6] An industrial steering committee has been actively utilised to ensure the practical relevance and value of the research, including operation and maintenance strategies to minimise future risks. A key resulting finding has been the risk posed by air valve chambers, with Boxall and Collins now acting as expert consultants for a UK Water Industry Research project in this area. An example quote of industrial impact is from Andy White, Asset Planning - Anglian Water: "one of the most useful academic exercises I've seen in recent years. Hopefully the work will reinforce understanding of a poorly understood risk Water Undertakers face every day". [obj. 4] Our active programme of dissemination and engagement has focused on industry and academia, but also with public engagement. We have substantially raised the profile and awareness of hydraulic transients and their impacts within the water industry. Evidence of this includes follow on funding to complete internationally unprecedented field monitoring campaign and the construction of operator training facilities by water companies, the design of which is fundamentally based on our research facility. The industrial and academic impact has been international, for example including engagement with the United States Environmental Protection Agency and collaboration with leading international groups across North America, Italy and South Africa. We have produced jointly authored international publications and were awarded 'best paper presentation' at the Water Distribution Systems Analysis conference in Australia. [obj. 7] |

| Description | Many UK water companies have built versions of the experimental facility developed for this research project to train and inform their operational staff. Training facilities with direct input from the research team include Severn Trent Water, Anglian Water, Yorkshire Water, Thames Water, Welsh Water, Northumbiran Water, and Scottish Water. Training and influence from this research has led to the 'calm networks' initiatives in the UK, which is seeing substantial improvements to levels of service from ageing water distribution infrastructure. Policy and practice relating to transients in water distribution systems have been influenced. For example practices associated with air valves and monitoring and management of large industrial users. Training has even included fire services and changed there practices for interacting with water distribution systems. Substantial media interest and coverage was generated coincident with publication of a major research paper from this research in 2015. This included a video produced by University of Sheffield media team, an interview on BBC radio Sheffield and articles in soft and hard copy media internationally. |
