Agenda

Day 1 Tuesday 13 March 2018

HOW DO WE ENSURE THAT OUR WATER NETWORKS ARE EFFICIENT - AND AT THE SAME TIME BUILD IN RESILIENCE AND SUSTAINABILITY?

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!

09.00    Introduction To The Summit

Frenk Withoos, Managing Director, ABB Measurement & Analytics Northern European Region

09.05    Chair's Introduction

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

09.15    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'.

Jean Spencer, Executive Director, Strategic Growth and Resilience, Anglian Water, UK

Nicci Russell, Managing Director, Waterwise (formerly Director, Ofwat), UK

Trevor Bishop, Director, Strategy and Policy, Ofwat (formerly Director, Environment Agency), UK

Mel Karam, CEO, Bristol Water, UK

10.15    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?

10.30    Refreshment Break

WATER DEMAND MANAGEMENT IN WATER STRESSED AREAS

What can we learn from water use regulation and WDM in water scarce regions like MENA and South East Asia?   Speakers from countries in these regions provide an insight into how their countries' water utility operating practices and regulatory policies promote efficiency among water operators and customers.

11.00    A State-wide Master Plan - Sarawak, Malaysia

  • Challenges in meeting customer demand in 'water stress' areas within the state

Mohammad Al Shafey, NRW Consultant, Aqaba Water, Jordan

11.40    Questions and Discussion

MANAGING UPSTREAM LOSSES - THE CHALLENGES OF LARGE DIAMETER PIPES

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?

TRUNK MAIN MONITORING

Sponsored by McCrometer

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

IMPROVING INFRASTRUCTURE BY PREDICTIVE MAINTENANCE

14.45    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

Michael Toh, Director of Water Services, Public Utilities Board, Singapore

15.05    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?

Francisco Cubillo, Deputy Director of Research, Development & Innovation, Canal de Isabel ll, Madrid, Spain

16.00    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?

ADVANCED NETWORK MONITORING

Sponsored by HWM Water

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. 

Julian Foster, Community Delivery Director, Wholesale Operations, Affinity Water, UK

09.30    Acoustic Noise Logging - The Technology

An update of the technology and deployment developments in telemetry-linked noise logging for leak detection. Key areas are:

  • Field experience of deployments in both a DMA environment and a non-DMA 'open' network
  • Technology and software developments deployed and anticipated
  • Extending out of the distribution network to trunk mains, using multi sensor input, and multi parameter analysis
  • Lessons learned, and where do we go from here?

ADVANCED PRESSURE MONITORING FOR INCREASED RESILIENCE:

Sponsored by: Syrinix

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)

Robert Anthony, Leakage Detection Manager (West), South East Water, UK

Mark Hendy, Sales Director UK/Europe, Syrinix, UK

10.15    Anglian Water's Shop Window - Meeting Future Challenges Now.

Over the next 25 years, demand will have to be met for the 1 million extra households predicted in East Anglia region of UK.  At the same time, Ofwat requires all water companies to reduce leakage by 15% by 2020.  The 'shop window' introduces and demonstrates technologies to address the challenge.

  • Smart networks and smart meters
  • Better knowledge of customer night use and leakage
  • Fixed acoustic monitoring
  • Thermal and Hyper spectral imaging drones to identify changes in soil temperature and localise leaks
  • Monitoring and mitigation of pressure transients

IMPROVING COMMUNICATION

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

PERFORMANCE BASED CONTRACTS (PBCs)

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

Siemen Veenstra, Regional Country Director Africa, Vitens Evides International, Netherlands

12.15    Questions and Discussion

WATER AUDITS

Water audits - and a water balance - are essential first 'diagnostic' steps to identify which areas of the network are leaking or losing income to the utility, and which operational policies and practices need strengthening - a precursor to introducing a successful NRW reduction strategy.

12.20    The NRW Toolkit

Audits have been used to quickly and effectively diagnose and plan improvement actions for reducing NRW throughout the MENA region and Africa. The NRW Diagnostic Tool, developed by the African Water Association (AfWA) and the Arab Countries Water Utilities Association (ACWUA), is based on a conceptual framework designed to enable more effective funding of NRW reduction projects in a collaborative manner. Utilities, in exchange for material resources and training, commit to the administrative and procedural improvements as specified in the NRW Toolkit

Moumouni Sawadogo, Inspector General, National Office of Water and Sanitation (ONEA), Burkina Faso

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.

12.40    Water into Supply - What Uncertainty Should We Expect?

  • Key results and key findings from the meter testing programme
  • Helping water companies understand what uncertainty they should expect from Distribution Input (DI) meters

15.00    Questions and Discussion

CUSTOMER INVOLVEMENT TO HELP MANAGE DEMAND AND INCREASE EFFICIENCY

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?

Katy Walker, Water Network Strategy Manager, Yorkshire Water Services, UK

15.25 Advancements In Measuring Customer Side Leakage And Demand

  • What has been achieved so far?
  • What are the results indicating?
  • Is household meter under-registration a factor to consider?
  • How will the study results help to shape future customer leakage strategies?

Reagan Hawkins, Leakage Technical Specialist, Dwr Cymru Welsh Water, UK

15.45 Questions and Discussion

15.50    Refreshment Break

CHANGING CUSTOMER BEHAVIOUR

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?
