The purpose of this UKWIR project was to gather information to identify and review the use of smart metering and smart networks for leakage management. To review the status of the water industry in the UK and Ireland and internationally both currently and looking towards the future with regards to how smart meters and smart networks can assist in improving and developing better leakage management. The project produced:

1) A report covering the detail of the current practices, looking forward to emerging solutions, identifying areas of opportunity for better leakage management, the benefits of smart networks and recommendations for UK and Irish water companies.

2) A technology scan reviewing smart metering and smart network products. The technology scan looked at both existing products that have had significant use by the industry and new emerging solutions some of which have the potential to transform the way water companies use smart networks for leakage management.

Measuring the Efficiency of Active Leakage Control

Reference: 19/WM/08/69
ISBN: 978-1-84057-878-2
Published Date: 21/10/2019

This project reviewed the appropriate measures of Active Leakage Control performance and how efficiency of Active Leakage Control activity can be meaningfully quantified in the context of explanatory factors. The project included a survey of water company and contractor representatives to understand in detail the motivations for assessing efficiency. Illustrative models at a number of levels using frontier efficiency analysis techniques were developed to allow both operational and strategic issues associated with Active Leakage Control to be considered. Water companies should build models of Active Leakage Control efficiency based upon the approaches described in this report. Once causes of inefficiency have been identified by models developed, water companies should implement any actions that can be identified to address these. Water companies should also use the outputs of Active Leakage Control efficiency models to understand how the costs of efficient activities compare to other approaches to leakage reduction.

The impact of reductions in leakage levels on reported and detected leak repair frequencies

Reference: 19/WM/08/68
ISBN: 978-1-84057-877-5
Published Date: 27/09/2019

This project investigated the impact of reducing leakage levels on the average frequencies of bursts and other identified leaks, including the proportions which are reported by the public and others, compared with those that are detected by Active Leakage Control.  The project included analysis of data sets supplied by several water companies.  There was no clear evidence in the data reviewed of an offsetting of increased detected leaks by fewer reported leaks as leakage is reduced.  As a result the total number of leak repairs would be expected to increase.  Water companies should factor the costs associated with additional detected leak repairs into the cost of leakage reductions.  Water companies should also monitor the number of leak repairs in parallel to the leakage level to ensure accurate budgeting of the full costs of leakage reduction. Data should be collated centrally with access provided where required for analysis.

Treated Water Storage Assets: Good Practice for Operation & Management Version 2

Reference: 19/RG/05/50
ISBN: 978-1-84057-871-3
Published Date: 14/08/2019

The purpose of this project is to provide water companies with good practice guidance for the whole life management of the construction, refurbishment, repair, operation and maintenance of treated water storage assets. Such guidance is mapped to the UKWIR Framework for Expenditure Decision Making in order to help asset managers, operators and capital investment planners better inform investment decisions to manage water quality risks.

The project was developed in conjunction with significant industry engagement, through two industry workshops involving representatives from UK Water Companies, Regulators, Academia and Industry, and five water company interviews. 

The project deliverables consist of:

  • a guidance document summarising good practices for the inspection, operation, maintenance, refurbishment, repair and new construction of treated water storage assets; and
  • a complementary spreadsheet toolkit illustrating a process to support investment planning activities for treated water storage assets through a condition assessment, deterioration and risk modelling approach.

Please note that this report – ‘Treated Water Storage Assets: Good Practice for Operation and Management – Version 2’, reference number - 19/RG/05/50 replaces the previous version (17/RG/05/48). The majority of the revisions made are to the sections on ‘external roof membranes (section 10.11)’ and ‘intelligent membranes (section 13.4.4)’ plus the associated table in Appendix 5. Please destroy or delete any copies of the previous version of the report that you have.

We apologise for any inconvenience this may cause.
