09.50 Regulator Panel: ‘Leakage Reduction In the UK Has Lost Momentum’- Are Water Companies Being Complacent?

UK companies have shown they can reach leakage targets.  But if they stop active leakage control and stop mending leaks, they fail their targets in subsequent years. Are UK companies doing enough to reduce leakage? Are they being held back by the regulators? Are water utilities being complacent? If so, shouldn’t the industry be taking a fresh look at ELL and targets?

  • Why is UK leakage still so high when we have done everything we can?
  • What are the challenges for getting leakage below 20%? Is background level of leakage much lower than first thought? 
  • Is ELL the right target – or should we set targets that reflect drought risk, resource availability and service delivery as well as leakage?
  • Is the UK 5 year pricing structure a barrier to putting improvements in place for longer term? Should we be going for a 10 year window to for longer term investment and sustainable improvements?
  • Making comparisons between UK regulatory systems

11.20 Understanding The True Value Of Water And Assessing How Measuring Value Can Assist With Leakage Measurement And Management

It is often suggested that we don't know the value of water or do not put a high enough value on it. Knowing the value of water is important for a number of key policy areas, including decisions on:

  • The choice between resource development, leakage control and demand management - should we prioritise leakage reduction even if it is not the least-cost way of balancing supply and demand?
  • Development of competition and water trading
  • Decisions on reducing abstraction to meet environmental needs

This panel will discuss how an agreed and robust way of determining the value of water is needed, and the significance of acquiring knowledge on how it varies according to what decision is being made, and where and when the water is being taken.

  • Highlighting the scale of change in leakage performance in Scotland since 2005 / 2006.
  • Scottish Water has set a good example outperforming the annual leakage targets – with record sustained leakage reductions year-on year, leakage has been halved and SW is already confident it will outperform its 2013 target.
  • What is SW now doing to ensure a progressive approach into the future?
  • What lessons can other companies/stakeholders learn from this?
  • Is a ‘Resilience of Supply’ Target more relevant to customers than a Leakage Target (‘sky to tap’ integrated water resources management)?

  • Demand will outstrip supply by 2030 (39%)
  • Wasteful consumer behaviour is the biggest barrier to meeting demand (45%)
  • Low tariffs fail to stimulate greater investment (33%)

Day 1 Afternoon Chaired By: Jack Carnell, Chair, EU Skills, and Former National President, Institute of Water, UK

15.00 Understanding How Pipe Installation And Leak Detection Technologies Can Improve Customer Side Leakage – Wessex Water Case Study

In the UK, customer service - and customer satisfaction generally – is an increasingly prominent topic. Leakage from company service pipes and from the customer side is receiving more attention.  Benefit schemes like free repairs is not a regulatory driver and gives no direct payback but is good for customer relations. But are customer side leaks being ignored and is adoption of service pipes the answer? Can we make improvements in the service pipe installation technologies and leak detection technologies?

  • Concentrating on improving customer service
  • Taking a fresh look at service pipe installation and jointing
  • Eliminating metal joints and minimising PE joints
  • New technologies for service pipe leak detection

15.25 How Accuracy Of The Customer Database And Billing Records Can Contribute To Minimising Apparent Losses; Maximising Revenue As Well As Reducing Leakage: North American Case Study

Traditionally the reduction of apparent losses has focused on meter errors, but with less  focus on meter reading and data handling errors and on the billing system and database.How customer consumption is handled by billing department has a big influence on losses. Is the accuracy of the customer billing database – and poor compatibility between databases - an overlooked contributor to revenue recovery?

  • Is database accuracy one of the issues addressed by regular (annual) water audits?
  • Data cleansing and building up customer knowledge and demand profiles
  • Describing a new customer billing system

14.00 New Developments In Pipe Wall Assessment Using In-line Technologies

Technologies for the inspection of pre-stressed concrete pipelines have been available for several years. These tools allow owners to identify individual sections of pipe in need of repair rather than unnecessarily replacing long lengths of pipelines. But for pipelines made with other materials, localizing damage to individual pipe sections has to date been cost or operationally prohibitive.

  • Development of new instrumentation allowing rapid acoustic testing of hoop stiffness, facilitating the inspection of metallic pipelines along with other materials
  • Demonstration of sensitivity to highly localized damage enabling focused repairs
  • Full scale testing on multiple materials, field testing of different instrument platforms and case studies

Peter Paulson,CEO and CTO, Pure Technologies Ltd

14.20 Questions and Discussion


Why are we ‘building in’ leakage when we replace pipes with more modern materials? Stemming the rate of rise of leakage requires better quality control – particularly in the case of polyethylene pipes and joints.  Can the quality of materials and pipe laying techniques be improved with better regulation and improved standards?

14.25 Assessing The Risks of Using PE Pipes And Using Specific Action Plans For The Polyethylene Life-Cycle: France Case Study

  • More than 4 million service pipes within Suez-Environnement
  • More than 90% of all new service pipes
  • 50% of mains up to 300mm (Lyonnaise des Eaux France)
  • Increasing number of leaks on PE service pipes on some sites

Jean-Jacques Marsaly, Senior Engineer, Suez-Environnement - Technical Direction, France

14.45 Questions and Discussion

14.50 Identifying Solutions To The Challenges Of Leak Detection In Pipe Networks Using Pressure Transients

How to find leaks in pipes made from this traditionally ‘difficult’ material when pipework configuration is ‘designed for the network and not for leak detection’? Are there alternatives to acoustic methods which find leaks accurately? Existing leakage pinpointing methods are heavily dependent on acoustic techniques

  • Limited effectiveness of all acoustic devices for quiet leaks (i.e. plastic mains) can result in slow, inaccurate leak pinpointing
  • Pressure transient techniques have been shown to offer a entirely new way of pinpointing leaks
  • Update on work to turn the prototype into a commercially viable device
  • Assessment and mitigation of potentially damaging pressure transients in water distribution systems

16.10 Pressure Transients In Trunk Mains: Diagnosis Of Leakage Pumping Transmission Mains Using Shut-Off Transients

The lack of reliable methods for the diagnosis of transmission mains - larger diameter pipelines with few service connections per km - is due to the fact that they are buried more deeply and in less accessible locations than distribution lines. Within such a framework, proper techniques are needed to save both time and money. In recent years transient test-based techniques (TTBT) have shown potential.

  • Experimental investigation of transients caused by rapid valve opening
  • Results achieved with the application of Portable Pressure Wave Maker (PPWM) for leak detection in the Milan water distribution system
