This programme area includes research into both the demand for water and the supply of water, with the concept of the supply/demand balance driving much of the work. Subject areas include headroom, demand management/water efficiency research. Water quality forms a large component of this research area, including epidemiology and microbiological studies, cryptosporidium, metals and algal toxins. Research also includes asset location, distribution operation and maintenance strategies (DOMS) and pipeline innovation, with leakage projects taking a high priority to help water companies reduce leakage to their economic levels.
Much of this research has been in collaboration with the regulators so that basic methods and frameworks can be agreed and applied.

BQ04-F01 - Horizon scan – Update of current knowledge of threats and mitigations Project Status Project Commenced In 2016, UKWIR commissioned a thorough review of knowledge across all areas that, at the time, were considered to be potential threats to the UK Water Industry reaching the BQ04 vision of achieving 100% drinking water compliance. A global literature review was complemented by extensive stakeholder engagement to set the scope of the study, to collate relevant knowledge and, most importantly, to tap into the insights of industry subject matter experts to best understand the likely risk posed by any identified gaps in knowledge. This valuable work has served to shape the BQ04 programme since then, helping to structure the research into a logical and deliverable project, with a clear strategic direction. However, the world has changed surprisingly quickly over the last six years: the water industry is now facing calls for action in areas that were not identified as significant risks in the initial work, for example micro plastics, micro fibres, and PFAS/PFOS. Such contaminants, whether scientifically warranted or not, are high on the agenda of not only water quality regulators, but also the environmental lobby, the media and thus the public and politicians. The world has also moved on in terms of the collective knowledge around the risks that were identified at the time, not least thanks to UKWIR’s efforts. It is now the right time to revisit this work, to update our knowledge with the latest research in this area, and to evaluate how the BQ04 programme is helping to address some of the gaps in knowledge identified in the original research. |

BQ02-A27 A review of the success of previous mains renewal methods and an overview of new techniques Project Status Project Commenced The UK water industry is aware that mains replacement programmes are not at the volume needed to create a healthy distribution network for future generations. In building Mains Rehab business cases the industry must be able to make good decisions as to the engineering techniques employed. |
|
BQ02-A30 Optimising the Selection of Pipes for Renewal to Reduce Leakage Project Status Project Commenced In the 1990’s and 2000’s, mains renewal programmes were principally driven by the need to improve water quality in pipe networks, under the Section 19 undertakings. More recently, mains renewals have been targeted more at improving serviceability, specifically burst frequencies and interruptions to supply. The selection of mains for renewal under these programmes was based first on data on water samples and water quality complaints, and later on data on burst frequencies. As all of these types of data can be allocated to specific pipes, it was relatively simple to target individual pipes for renewal. Now, with the current focus on reducing leakage levels, leakage has become a major driver for mains renewal, if not the principal driver. However, leakage is not normally measured at the level of individual pipes, but only at DMA level. In reality leakage is rarely uniformly distributed across a DMA, but instead some pipes leak more than others within the DMA. In order to optimise the economics of a mains renewal programme driven by leakage reduction, a method is required to determine which pipes are leaking most in order to target the investment to maximise the benefits. Currently, as such a method is not generally available, mains are selected on the basis of historical burst numbers, using burst frequency as a surrogate for leakage. In reality, burst numbers are a poor indicator of leakage levels. |

BQ02-C33 Use of models to determine the size and most likely location of CSL Project Status Project Commenced Leakage on customer supply pipes and communication pipes is estimated to be a significant proportion of the total leakage. At present leakage is only detectable on communication and supply pipes either if the property is metered, or if there is an acoustic device nearby or if it is picked up on an active leakage control sweep of the DMA. Even is a property is metered, unless AMI or frequent AMR is deployed, then the average leak run time on a supply pipe before discovery is likely to be three months (based on six monthly reads). As a result, although the volume of a leak on a supply pipe or communication pipe may be small, they will typically run for a significant length of time. In recent years, the use of mains models to predict the likely location of a failure have increased. These models typically look at the previous failures within an area, the network model and mains materials and other environmental factors (weather, traffic loading, demand) in order to produce a “most likely” point of failure. This reduces the time spent sweeping the DMA by directing ALC responses to the optimum locations to search for a leak, and additionally can be used to drive mains replacement programmes. At present, these solutions concentrate on mains failures. However, there would be considerable benefit to these solutions being extended to the prediction of supply and communication pipe failures. Validated models that proved successful at predicting failures would not only reduce location and leak run times but additionally allow more targeted replacement polices. |

Understanding water infrastructure risks - major bursts, traffic volumes and the condition of road infrastructure. Project Status Project Commenced A number of companies experienced a rise in the rate of bursts on larger diameter mains in 2022, a number of these occurred at or close to sizeable road junctions. There is a hypothesis that the condition of the road and the volume of traffic at these road junctions and has contributed to failure of these mains. When a vehicle hits a pothole, and a shock is felt within the vehicle, however that shock wave will travel down through the road towards the water mains, but does this increase the risk of failure and how can that risk then be monitored to allow risk mitigation measures to be taken. Over the years we have had a number of major bursts at large road junctions. There are many reasons why we have burst, transients being a common factor, but does significant vibration/shock due to vehicles also result in premature/catastrophic failure or significant risk to major water distribution infrastructure. Should we consider the volume of traffic and the condition of road surfaces as significant risk to major water distribution infrastructure and how would we mange that risk. |

BQ0-A06 Assessing the levels of leakage on new polyethylene networks Project Status Project Commenced If the UK water industry aspires to achieve zero leakage from its distribution networks, it is clearly essential that all newly laid networks are leak-free when they are laid and remain leak-free throughout their economic lives. However, a major UKWIR study published in 2010 (Report No. 10/WM/08/43 – “Leakage from Polyethylene Pipe Systems”) determined that leakage levels from recently laid PE networks were indeed significant. This report concluded that, although burst rates per unit length for PE pipes were lower than for other pipe materials, there was “no significant reduction in leakage in DMAs with a high proportion of PE pipework”. If this is still the case today, then clearly the water companies and their contractors need to take urgent action to rectify the situation. However, the data presented in the 2010 UKWIR report is now all at least 15 years old. Some improvements in field procedures, training of operatives, and non-destructive joint testing have been introduced since then. Furthermore, very little of the data collected for the study were from DMAs which comprised 100% PE mains and services, and the report postulated that the persistently high leakage levels may have been due to increased leakage rates on the remaining non-PE parts of the system. In many of the DMAs used which were not within new housing developments, all, or most of the old mains, and in some cases the communication pipes, had been replaced with PE. But generally, the supply pipes had been disturbed but not replaced, probably resulting in increased supply pipe leakage. Consequently, while much anecdotal evidence remains to suggest that leakage on new networks is still significant, no more recent quantitative evidence has been collected at national level to support this, and even the 2010 report is questionable. |
