Day 1 Tuesday 13 March 2018


The volume of water lost from leakage (physical losses) and from inaccurate customer meter readings and theft of water (commercial losses), together add up to Non-Revenue Water (NRW).  Volumes of NRW can be very high, with utilities frequently losing half the annual volume of water they produce. With better access to updated water company data a recent study estimates that global NRW is in excess of 100 billion m3 per year.

It is therefore no surprise that managing and reducing leakage and NRW is still one of the major operational tasks facing water utility operators, and one of its biggest headaches!

08.55    Introduction To The Summit

09.00    Chair's Introduction

Bob Taylor, Operations Director, Drinking Water Services, South West Water, UK

09.10    Keynote Panel Session: Ensuring Efficiency, Sustainability And Resilience Of Supply

Resilience is affected by climate change and drought. In the light of climate change mitigation and adaptation regulators and operators are putting a greater emphasis on water efficiency - not previously part of economic regulation. With a predicted 20% increase in UK's population over the next 20 years, much of it in drier areas, and a predicted 20% reduction in summer rainfall by 2050, as well as the risk of too much water being taken from rivers, the key lies with demand management, a policy that is now firmly  'at the heart of resilience'.

Mel Karam, CEO, Bristol Water, UK

10.10 - 10.20    Questions for the Panellists and Audience Comments (led by Chair)

Standardisation of leakage reporting in the UK is providing a major 'political' challenge to the water companies. How will changes to the accounting process impact on customer perceptions? Ofwat has kick-started the further downward progress in UK leakage post 2020 by requiring a 15% reduction).  How will this be achieved in an environment of low Capex and limited infrastructure renewal?

A recent spate of dry weather - 9 months of low rainfall - caused companies in the South East of England who are groundwater fed to have concerns over resilience. Are more robust water demand management (WDM) measures needed for this region? Will water retail competition result in greater efficiency and reduced demand from non-household customers?

Water utilities face many challenges including aging infrastructure, constrained resources and revenue shortfalls. Most utilities use various technological resources to manage their assets and increase efficiency. Unfortunately, those resources are often managed in 'silos'. In some cases, data and analytics are employed by different departments without the knowledge that similar systems might already exist in other parts of the same utility. These cases create missed opportunities as utilities can gain insights and harness better intelligence through data and analytics compiled from various business functions.

10.20     Advanced Strategies for Sustainable Water Loss Reduction

By developing a strategy to integrate and capitalise on new and existing technologies, utilities can:

  • Respond proactively to network faults
  • Improve their usage of information to enhance the customer experience 
  • Improve their asset management strategies to better predict future needs 
  • Reduce water losses and ensure sustainability of water supplies 
  • Improve operational response management

11.55    Questions and Discussion


Large diameter trunk (transmission) mains have always been the 'bĂȘte noire' of water networks - they are invariably large diameter, at low pressure, made of non- metallic materials, and often laid in rural areas - the worst combination for meter selection, meter accuracy, leakage monitoring and leak localisation.  It is one of the most difficult areas of the network to monitor, but one which is essential for a correct water balance. What technologies can best address this scenario?

14.45   Accurate Metering In Large Pipes Using A Full Profile Electromagnetic Insertion Meter

Accurate measurement of flows in large bore pipes across the network can be very challenging. Trunk mains are often difficult to access, flow meter selection can be varied and there is usually a trade-off between location, cost and accuracy

  • Reviewing the challenges of measuring flow in large diameter transmission mains, both existing pipes and new installations
  • A new technology being adopted for meeting challenges of flow measurement in trunk mains and the pipe network

15.05    Driving Leakage Down Even Further: Singapore Case Study

The Public Utilities Board (PUB) in Singapore, despite having one of the lowest leakage rates in the world, wants to be 'the best in the industry' and have just let a 150million SD (110 million USD) contract to examine the condition of their cast iron pipes. PUB shares their results to date with us.

The challenges PUB faces are:

  • Growing population and economy
  • A growing asset base and ageing infrastructure
  • Urban congestion and a complex network with open zones
  • Predictive maintenance and pipeline condition assessment is one way of meeting the infrastructure challenge - selective pipe repair, rehabilitation or replacement

Ridzuan Ismail, Director of Water Supply Network Department,Public Utilities Board, Singapore

15.25    Asset Management - 'Age Is Not Important But Calm Networks Are'!

Age is not necessarily a factor leading to pipe deterioration and increasing burst frequency.  But pressure transients and sudden hydraulic changes to the network are a major cause of pipe breaks. 

  • Can we predict pipe breaks?
  • By modelling historic pipe burst events and the estimated cause of failure?
  • By analysing the causes of transients?
  • Will this help to solve the 'repair or replace' conundrum - ie by planned maintenance?

16.20    International Industry Leaders Panel Session: Innovation For Efficiency And Resilience

International water utility senior directors address key issues, followed by audience discussion. 

  • Is the international water industry sufficiently funded when it comes to advancing water loss reduction?
  • Is technology innovation water utility led or supplier led, and should utilities take the lead in sponsoring and funding innovation?
  • If industry led, how do we introduce a 'culture of innovation' to develop new technologies?
  • We hear much about better technologies for monitoring and finding leaks, but where are the innovative technologies for repairing leaks?  Could pipe repair technology development be an essential part of innovation funding?
  • Can innovation also be applied to the workforce - to change mind-sets and encourage upskilling?
  • What can both water companies and regulators do to promote and influence a culture of innovation?

17.30    Questions and Discussion

17.35   Systemic Effect on Electromagnetic Flowmeter Performance

While the EM flowmeter is an attractive flow sensing device, measurement accuracy when operating under adverse conditions cannot be compromised. It is important to understand flowmeter performance when installed under field condition. In this study, a multiphysics model of the EM flowmeter, working on finite element (F.E.) analysis was created with capability to predict performance with high accuracy.

  • The model evolved into an invaluable tool in understanding flowmeter performance with minimum testing efforts and aided design improvement efforts.  
  • More recently, the model has been extended to simulate the flowmeter incorporated in the piping system with flow modifying structures 
  • It is envisioned that going forward, such models could help correct flowmeter calibration factor in a given installation setup, thus ensuring measurement accuracy

Leaks 'dialling themselves in'? This sounds like leak detection Utopia!  But what are the costs - and the economic payback - of permanent monitoring? How are these vast amounts of data managed - and used to best effect?  And do we still need DMAs - or are they being replaced by permanent monitoring and customer use surveys?

09.10    Permanent Network Acoustic Monitoring: UK Case Study

There have been great developments in acoustic sensor technology over the last 20 years, and one UK water company, Affinity Water, has just undertaken the largest ever deployment of telemetry linked noise logging with 20000 units installed in an area of their network.

Advanced Pressure Monitoring - detailing the benefits, insight and increased network visibility that high sample data can provide - detecting and locating the source of events. South East Water, in collaboration with Syrinix, has been demonstrating the benefit of permanent high resolution monitoring across their networks. Advanced pressure monitoring, with continual high resolution data, shows that not only can network events be detected but they can also be localised by triangulation across multiple devices

The key aims of the project were to demonstrate that burst events can be detected, classified and localised to determine the necessary response, enabling proactive interventions, and delivering cost beneficial serviceability improvements against Interruptions to supply, water quality and leakage outcome delivery incentives (ODIs)

11.10    Can The Internet Of Things Help To Handle 'Big Data'?

Leakage and water network management has always depended on gathering regular data from the field, but with the increased spread of sensors across all parts of the network the amount of data to analyse and manage is increasing. The latest Internet of Things (IoT) communication solutions offer the potential to vastly increase both the number and the data frequency of network sensors. SES Water is developing a prototype smart metering network to test out the capabilities of these IoT solutions and their potential applications within the Water Industry.

  • Development of an innovation culture
  • Introducing new technologies into the Water Industry
  • The 'Smart Water Network' - an innovative network built on enhanced sensors, a communication layer, intelligent processing, intuitive graphical displays and workforce mobilisation

Jeremy Heath, Innovation Manager, SES Water, UK

11.30    Questions and Discussion


Is 'contracting out' some leakage strategy operations more cost effective than training and using in-house staff?  What operations tasks are most suited to PBCs and which are not?  With an ageing workforce, and the difficulty of attracting young staff, is contracting out part of the solution? There is now a wealth of experience in the challenges, cost-benefits and lessons learnt from implementing PBC NRW case studies across the world. 

11.35    Bahrain Case Study

Lessons learnt from the Bahrain NRW Project reflect many similar international PBC studies:

  • Realistic time period
  • Project ownership and understanding
  • Cooperation between stakeholders and independent monitoring
  • Appropriate performance monitoring
  • Knowledge transfer and relationship management

Dr Hana Al Maskati, Head, Leakage Detection and Control Group, Electricity and Water Authority, Bahrain

11.55    NRW Is Not A Major Problem - But Knowing The Solution Does Not Always Solve It

  • Just knowing what has to be done to reduce NRW does not mean it will get done!
  • There is a big gap between awareness of the problem and knowing what to do to put in place a strategy
  • The ability to collect and systematically analyse data requires basic education in creativity and critical reflection
  • Getting corporate culture to mobilise human resources for NRW reduction requires leadership and management

12.20    Driving Investment in Strategic Infrastructure

Although Sustainable Economic Level of Leakage (SELL) has been used to drive leakage management and network rehabilitation of distribution mains, it has been less effective in addressing middle ground leakage. Where SELL is applied on strategic infrastructure, it can often determine that the cost of maintenance is far greater than the cost of water lost, and is therefore uneconomic. However, where leak-before-break (LBB) principle is applied, the case for investment becomes far more compelling.

When LBB is applied, leakage becomes not only a factor of non-revenue water, but also has far reaching consequences in terms of:

  • Third party damage impact
  • Public health and safety
  • Large-scale interruption to supply.

To calculate and manage the true economic level of leakage for transmission mains requires a more strategic, risk-based approach.

Ross Fisher, CEO, Minerva IAM, UK

Water into Supply is the largest component in the Water Balance. Between 2012 and 2017 a significant number of independent tests have taken place to assess just how good large diameter Electromagnetic and Ultrasonic meters are.

14.40 Using DNP3-WITS Water Telemetry Standard for Gathering Flow and Pressure Data from District Metered Areas: The Canadian Experience

In 2016, Guelph Water Services, a Canadian drinking-water utility with a service population of 140 000, embarked on a project to upgrade and expand district metered areas (DMAs) in its distribution system:

  • DNP3-WITS (water industry telemetry protocol) is now used to gather flow and pressure data from magnetic flowmeter units located throughout the city.
  • Guelph Water is the first deployment of DNP3-WITS protocol in Canada.  
  • The DNP3-WITS protocol features automatic time-stamping of data, built-in store/forward data-logging, and remote configuration/diagnostics. 
  • The DMA flow and pressure data is used to track leakage, audit customer metering, prioritize piping repairs/replacement, and for the city's hydraulic model.

Graham Nasby, Water SCADA & Security Specialist,City of Guelph Water Services, Canada

15.00    Questions and Discussion


Can operators work more closely with customers to help drive down leakage?  Customers are already encouraged to report visible leaks or changes to pressure, but can they accept behaviour change to become more active in managing their demand and reducing per capita consumption?  This will require accepting new developments like retrofitting water-efficient household devices, introducing compulsory household metering and 'smart meters' to identify excessive use and leakage in the customer's house, and a greater emphasis on rainwater harvesting and effluent re-use. 

15.05    How A Water Company Can Take Responsibility For The Water Environment For Good

Night flow is a well-established tool for estimating components of leakage. But can water companies really distinguish between intermittent use, genuine continuous use, plumbing losses, and, most importantly, what is attributable to supply pipe and distribution leakage?

Water companies are looking at smart metering and other technologies to identify what is happening on the customer side. This may well account for the majority of leakage, but:

  • How do water companies quantify it, account for it and tackle it?
  • How do they justify investing in finding and fixing a large number of leaks with such small savings economically?
  • What responsibility do water companies have for customer supply pipe leakage or for plumbing losses?
  • How do regulation changes, now and in the future, influence water company decisions?
  • Will the eventual development of in-pipe repair technologies be another influence?

15.45 Questions and Discussion

15.50    Refreshment Break


Behaviour change and behavioural economics is fascinating.  What incentives persuade people - and encourage others - to take part in a programme of home retrofit to promote water use efficiency and reduce demand? What level of savings can be made? 

Waterwise has found that around 4% of water-efficient (dual flush) toilet cisterns fitted to new homes leak, losing on average 215 litres per day per cistern - 400 million litres per day. So, as well as retrofitting programmes, do we need a new strategy to train and certify plumbers and builders to remove poor practice and ensure high quality installations?

16.20    A Whole Town Approach to Reducing Customer Demand

Northumbrian Water Group has introduced an innovative 'whole town' approach to community-based social marketing - the 'Every Drop Counts' programme.  Following audits of water use in 25000 homes, the water company is working with customers and plumbers who want to take up the retrofit scheme:

  • An increased awareness and activity around internal plumbing losses
  • Identification and repair of leaking WCs 
  • A saving of 22 litres per house per day for the 20% of customers who have taken part in the scheme

Tim Wagstaff, Demand Planning Project Manager, Northumbrian Water Group, UK

16.40    Can Smart Metering Make A Difference? 

Smart metering is not just about giving customers a more accurate bill - it can be an aid to finding leaks on customer supply pipes and in the house.  It can also be a big driver to reducing leakage and customer use. 

Thames Water's smart metering programme is well underway, demonstrating the evolution from 'dumb' meters, through automated meter reading (AMR) to full blown advanced metering infrastructure (AMI), with increased confidence for future roll-out:

  • What are the drivers, the technology and the evolutionary process on the journey towards universal smart metering?
  • How can further benefits be demonstrated by this mature case study from Thames Water?
