BQ Achieving zero leakage by 2050: Project 1 - Use of smart meters and smart networks for leakage management

The aims of this project will be to:

*Investigate and document the smart network technologies which are now available, and which water companies are currently using them, throughout the world.

*Gather information and data from those companies which are using smart network technologies, specifically with reference to how these technologies are being used to support leakage management.

*Identify the opportunities for better leakage management from the following, amongst others :

>>More data; different data; more frequent data; better quality data, etc

>>More permanent monitors with greater processing power

>>Rapid integration with other data sets – e.g. AMR data from customer meters

>>Real time analysis and diagnosis

>>Live modelling

>>Advanced pressure management and transient control

*Real time transmission of outputs to field staff

*Describe the advantages and disadvantages for leakage management of the different types of smart technologies with different levels of data discrimination.

*Make recommendations for the most useful technologies for leakage management.

A Water Industry ‘Club’ Project - Cost effective techniques for sewer rehabilitation

A review of the different rehabilitation techniques available, their applicability to the assets (network, manholes, chambers, sewer rising mains, etc.) and the level of implementation within the industry. Applicability of different rehabilitation techniques must be considered in terms of performance depending on the existing sewer pipe material as part of the review.

 A review of research into sewer rehabilitation techniques and implementation globally, e.g. evaluation projects and interpret findings into the effectiveness and longevity of these techniques.

Analysis of the performance of the rehabilitated assets including root cause analysis of subsequent failures where they have occurred. A statistically sound range of examples should be taken and analysed to help understand the impact of sewer rehabilitation on asset life and performance. The performance of different types of rehabilitations i.e. patch liners versus full length should be considered.

Project scope to include:

1.       Review of the different current and emerging (from other geographies) rehabilitation techniques (e.g. sock liners, spray liners, cured in place patches (in terms of longevity, strength, resistance to ground water infiltration and ingress particularly the durability and performance of renovation methods and the success of installing against active infiltration), LED lamps and resins being developed for curing patches, liners, and formed in place PE pipes, etc.).

2.       Project to consider the following:

·         H2S (growing issue for utilities) and best practice to renovate or protect CP pipes and structures. Consider what happens to the affected structure after CIPP or coating is completed.

·         Appropriate renovation of brick sewers and other problem pipe materials, such as PF which will become an increasing burden with the takeover of S105a sewers.

·         Other replacement or upsizing systems to address network capacity issues through no-dig such as bursting or discreet MH to MH replacement systems. i.e. In2 and Snap-it etc.

·         Understanding the short and long term impacts of rehabilitation on serviceability performance like blockages, root ingress, and infiltration reducing available capacity.

·         Analysis of liner performance with respect to host pipe material and diameter, curing techniques.

·         Analysis of general maintenance activities and impact on various rehab techniques (e.g. jetting operations resulting in shedding of inner foil lining of CIPP).

·         Opex benefits, i.e. reduction of silt accumulation in lined sewers, saving on cleaning and tankering.

·         Costs associated with serviceability impacts or the customer impact of these issues, and the benefits of the lining.

·         Whole life costing of rehabilitation techniques.

·         Review of accelerated aging testing on various rehabilitation techniques undertaken by the supply chain or academic material experts.

·         Determine successes and failures modes of various technologies.

Review of utility Standards and identify if these are adhered to. Determine level of inspection/testing of installation applied by contractors. Identify the potential of developing a standard “sand box” type test so that random tests can be carried out on patch repairs in the field. The level of Quality Control implemented at installation stage may have a significant bearing on the effective life of any rehabilitation works and should be reviewed in the context of historical data.

 Above points to include a minimum number of examples from each participating company.

Achieving Zero Leakage by 2050: Phase 2: Understanding the balance between customer use, supply pipe leakage and plumbing losses in water delivered to household properties

This project will use recently developed flow estimation techniques to investigate these factors across a representative sample of household properties within several water companies.  

The data obtained will be used to provide greatly improved estimates of: 

  • Plumbing losses, which are part of consumption
  • Water running into storage at night, also part of consumption
  • Background leakage on underground supply pipes, which is part of the total leakage KPI

Achieving zero leakage by 2050: Project 2 - Incidence and causes of repeat bursts at old repairs

The objectives of the project will be:

(i) To assess the proportions of bursts on mains of different materials which occur as a result of the failure of a previous repair, and thereby to determine whether this is a significant problem.

(ii) Where bursts have occurred at the site of a previous repair, to determine where possible whether these have resulted from deterioration of the materials used for the repair over time, or by faulty workmanship at the time of the original repair.

(iii) To provide guidance for maintenance operatives carrying out repairs, on how to minimise the likelihood of future failures

Active Leakage Control efficiency in the SELL calculation Renamed: Active Leakage Control Efficiency

Active Leakage Control (ALC) is defined as the processes by which companies identify, detect, locate and eliminate water losses caused by leaks which are not visible on the ground surface.  Very little work has been done on the efficiency of ALC. It is very unclear how this should be defined or how it can be quantified.  Nor is it clear what levels of efficiency should be achievable within water company operations.

 This project would investigate alternative definitions for ALC efficiency, and alternative parameters for measuring it. It would establish which are the most useful definitions and measures, and then gather data from companies to establish what levels of efficiency should be achievable within water company operations. Finally it would consider the most practical way to incorporate this into SELL calculations, allowing for companies’ future aspirations for ALC efficiency.
