Deriving a Best Value Water Resources Management Plan

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.

WRMP 2019 Methods – Decision Making Process: Guidance

Reference: 16/WR/02/10
ISBN: 1 84057 813 0
Published Date: 25/11/2020

As part of the UKWIR WRMP 2019 Methods Programme, the Decision Making Process Project was commissioned to provide a revised and updated decision making framework which reflects the evolution from the Economics of Balancing Supply & Demand (EBSD) framework (2002). It aims to guide water resource planners on framing the problem and on addressing it using the full array of feasible techniques (both old and new).
The decision making framework provides a clear, auditable and systematic process for planners to follow in relation to the development and application of decision making approaches for water resource planning. This decision making framework should be read in conjunction with the parallel UKWIR Guidance on Risk Based Planning Methods. Both projects form part of a linked investigation into risks, uncertainty and alternative approaches to WRMP decision making that can be incorporated into the development of WRMPs.

Drought Vulnerability Framework

Reference: 17/WR/02/12
ISBN: 1 84057 846 7
Published Date: 18/12/2017

The Drought Vulnerability Framework (DVF) provides a framework of methodologies to enable water companies to better understand the vulnerabilities of their water resource zones to drought.  It builds on the concept of the Drought Response Surface (DRS) originally derived for the Environment Agency ‘Understanding the Performance of Water Supply Systems during Mild to Extreme Droughts’ study (report Ref SC120048/R).  The DVF has used case study examples as a proof of methodology across the range of available data and behavioural models that currently exist within WRZs in England and Wales, to calculate the required inputs to the DRS.  The DRS contains information about drought response and risk to provide companies and stakeholders with a more comprehensive understanding of system resilience to droughts of different durations, in a consistent format. It also highlights critical drought durations for a given WRZ and provides an indication of potential periods of ‘failure’ under droughts of different durations and severities.

Future estimation of unmeasured household consumption

Reference: 17/WR/01/16
ISBN: 1 84057 830 0
Published Date: 13/07/2017

A robust estimate of the unmeasured household consumption is an essential component of Water Resource Management Plans, Business Plans and annual reporting.  As domestic revenue meter penetration increases, unmeasured household monitors are becoming more difficult to maintain.  The report’s objective was to identify suitable methods for the estimation of unmeasured consumption in the future.

The current best practice guidance has been reviewed, and in its current form does not contain sufficient guidance to allow companies to adapt their existing monitors to the changing level of metered properties.

Seven potential options for estimating the unmeasured household consumption have been identified that are suitable for circumstances where meter penetration is increasing.  These are all described in the report, and allow companies to develop a reducing cost solution to estimate unmeasured household consumption.

The report contains several recommendations where existing evidence and guidance needs to be strengthened or explored further.
