Integrating UKCP18 with UKWIR tools and guidance: Review of existing methods

This project has systematically reviewed UKWIR methods and tools in the context of climate change following the Met Office’s recent release of the latest UK climate change projections (UKCP18). This review has particularly focussed on water resources and drainage and has taken into account current usage, industry needs into the future and the potential impact of adopting the new UKCP18 projections. As part of this, comparisons between the range of UKCP18 products with those available under UKCP09 are presented and, given the broad similarities between the projected impacts, recommended that urgent action in relation to submitted plans was not required. The study’s prioritised recommendations for updates to methods and tools has also considered other ongoing complimentary research and industry studies and has identified key research gaps for the future, recognising that the water industry methods are undergoing significant evolution at this time.

Improved Understanding of current and future household consumption

Reference: 21/WR/01/17
ISBN: 978-1-84057-916-1
Published Date: 28/04/2021

The UKWIR project ‘Improving Understanding of Household Consumption’ collated and analysed water metering data to explore patterns in demand for water. The project used innovative data analysis methods to separate measurements of individual household use into ten weekday and ten weekend profiles. These were then interpreted with reference to environmental and socio-economic factors and their influence on customer behaviour. Changes to patterns of water demand through time were also explored. The project report included:

  • Detail of the processes applied for data collection and management, the methodology used to partition households into ‘clusters’ and the results of the data interpretation.
  • Guidance for water companies and other organisations on the implementation of the methods presented, including supporting information on which methods to use and practical guidance.
  • Recommendations for the development of a longitudinal study of household data, to ensure that data collected in future are suitable for data analysis.

WRMP19 Methods – Household Consumption Forecasting

Reference: 15/WR/02/9
ISBN: 1 84057 805 X
Published Date: 25/01/2021

The Household Consumption Forecasting Guidance Manual provides practitioners with technical guidance on how to forecast household water consumption.  It presents methods to determine the most appropriate approaches for use, depending on the ‘level of concern’ in a water resources zone. It provides an outline of different forecasting methods, identifying data requirements and pros and cons of each.  It includes sections on understanding the factors that influence household consumption, methods for segmenting customers (e.g. by meter status), dealing with weather effects, and uncertainty.  The guidance has been developed to link with other UKWIR reports that support the WRMP19 water resources planning guidelines, including methods on property, population and occupancy forecasting and risk based planning.  The manual sets out several alternative methods to the micro-component forecasting approach that has been used by the water industry for a number years.  It also includes a case study of an imaginary water resources planner.  The manual is accompanied by Supporting Guidance which presents the results of stakeholder consultation; a review of the factors that influence consumption and further background on methods for forecasting household consumption.

Deriving a Best Value Water Resources Management Plan

Reference: 20/WR/02/14
ISBN: 978-1-84057-905-5
Published Date: 05/12/2020

The UKWIR research project “Deriving a best value Water Resources Management Plan” was commissioned to provide a comprehensive framework and guidance incorporating technical, economic, environmental and legal perspectives to allow organisations to derive a best value strategic water resources plan (WRP) in the UK and Ireland.  The project has developed a best value WRP framework which includes support guidance on environmental regulations, regulator engagement, stakeholder engagement and customer engagement.  The generic approach within the framework is based on multi-criteria decision analysis (MCDA) and sets out the steps that planners can follow to develop their best value WRP.  The framework provides a definition of a best value WRP and identifies principles of best value planning.  The deliverables include a final report and a practitioner’s guide.  This project ensures that companies and regional groups have a framework they can use for best value planning.
