3 INTRODUCTION The Importance of Optimising Pressure - Every Metre Counts Thousands of i2o s pressure management solutions are deployed in utilities around the world to optimise the performance of their water networks. i2o s technology is delivering dramatic reductions in leakage and burst frequency, network lifespan extension, reduced energy and manpower requirements, and improved customer service levels. i2o has now introduced the next generation of pressure management technology, Smart Pressure. provides the most comprehensive high performance technology platform for the management of pressure within a Smart Network. It builds on the existing strengths of i2o s solutions; the combination of network visibility and intelligence with the remote control and automatic optimisation of pressures. adds the following capabilities: 1. A single technology solution that can manage all aspects of pressure management on a network wide basis. 2. All relevant network intelligence is visible at the click of a button and is available to anyone who needs it within the utility, not just the pressure management specialist. 3. Easy to use, easy to integrate tools to remotely manage pressures in a range of different ways across the network. 4. The most advanced automation and intelligence available today for managing pressures, providing utilities with unprecedented precision in their control of pressures. The significance of providing all of these capabilities in a single, scalable, rapidly deployable technology platform is that it enables a unique level of flexibility and agility. The right level of pressure management can be implemented quickly and easily when and where it is required in each part of the network. The i2o solution is built on a robust, secure hardware and software platform, which can be easily integrated with both today s systems and data repositories, and within the Smart Water Network architectures of tomorrow. technology positions utilities to put pressure management at the heart of their day-to-day operational network management. Pressure management can now be a core element in delivering an outstanding service to water utility customers at a more cost-effective price. There are many challenges to the efficient and effective operation of the network. Leakage levels often remain high. Water distribution is an energy intensive business wherever it needs to be pumped. Burst rates are on the rise as the network infrastructure ages. Replacing sections of network is expensive, requiring large capital investments. But with most networks still controlled manually, the operational costs of managing these challenges are escalating. It is no surprise that many water companies are struggling to improve their customer service levels. The management of pressure is central to tackling all these issues. Pressure needs to be consistently high enough to satisfy the customer, but excessive pressure drives up leakage, burst frequency, energy consumption and operational costs, whilst decreasing the lifespan of network assets. So the goal of pressure management is pressure optimisation. It is all about being able to precisely control the pressure that you are delivering to your customers so that you can deliver the right pressure, but no more. The precision with which you can control pressure is vitally important. If your control of pressure is weak then you will need to target higher pressures to take account of excessive pressure variations in order to ensure levels of service are maintained. Leakage rates are typically directly proportional to average pressures. Where the network is prone to bursts, small changes in maximum pressures can significantly increase burst frequencies, increasing repair costs and reducing the lifespan of the network. The energy consumption of pumps relates directly to the average pressures in that zone. In pressure management, pressure control is everything and every metre really counts. Once the technicians have installed the remote control devices and set them up, that s the last time we need to visit the site. All the optimisation and control that follows is done from the back office. It s almost like having a SCADA system on your network. Keith Hilson Head of Leakage, South East Water 3

4 i2o s architecture technology positions utilities to put pressure management at the heart of their day-to-day operational network management. 5 The challenge of accurately controlling pressure is complicated by the fact that pressure varies uniquely across each part of each network, constantly shifting with changing patterns of demand and outside events. Because of these variations, initial approaches to pressure management (such as fixing pressures or basic time or flow modulation) will often not deliver the optimum pressures in the network. These basic pressure management techniques either lock in a pressure level that is too high (or too low), or are unable to respond effectively to the changing demands on the network. i2o s introduction of Advanced Pressure overcame these shortcomings with technology enabled to automatically and continuously optimise pressure across the network, based on the current demand patterns and operating characteristics of that area of the network. The second generation of solutions from i2o delivers these capabilities as part of an intelligent, network-wide technology platform, designed to deliver even greater ease of use, enterprise scalability and flexibility, and even lower total cost of ownership. The architecture for this next generation of Smart Pressure solutions is built around a new set of enterprise class software-based services, combined with highly intelligent loggers and controllers in the network to monitor network performance and control assets such as PRVs and pumps. Thanks to i2o s technology we have unlocked around 30% of our operators time, as they no longer need to manually schedule and carry out changes. Jalil B.

5 The i2o Journey The implementation of can best be thought of as a journey. Different water utilities will be starting that journey from different levels of maturity in their pressure management practices. Across every network there will be different levels of requirement for different parts of the network which will change and evolve over time. The i2o products are designed to provide the market leading solution for each level of the journey. The foundation for is to establish Pressure Managed Areas (PMAs), with inlet pressures fixed by Pressure Reducing Valves (PRVs) or variable speed pumps. These PMAs are usually also District Metered Areas (DMAs), equipped with bulk meters to provide the benefit of leakage and demand monitoring. Depending on business priorities and the current status of the network, water companies may then implement one or more of four principal levels of management, starting at whichever level is appropriate for each area or pumped zone: Level 1 Implement or add loggers to obtain data on pressure, flow and temperature in the network. Level 2 Achieve or improve visibility through network monitoring. Level 3 Implement remote control of network assets to enable basic pressure management at considerably lower operational cost. Level 4 Introduce automatic optimisation of pressure, based on the current demand patterns and the operating characteristics of each PMA or pumped zone. i2o provides robust, high quality, intelligent Loggers that accurately log data at the inlet, critical point and AZP. i2o s next generation loggers have a unique collection of capabilities that put in place a platform for. For example our over the air upgrade capability enables the delivery of new functionality without replacing the physical device. Unlike traditional logging devices, i2o Loggers can also act as pressure controllers or transient detectors through a seamless in-situ upgrade process. To make i2o Loggers as cost effective as possible they are provided with a data management service that enables full online remote management of the device and includes unique features such as hot-swap, whereby a new physical device can inherit the configuration of the device it is replacing. Level 1 - LOGGERS i2o s intelligent Logger Working with i2o has been an extremely positive experience. They re very proactive, and they understand our business and provide the right solutions for our particular circumstances, rather than a one size fits all approach.

6 The i2o Journey 9 Level 2 - NETWORK MONITORING ump Level 3 - REMOTE CONTROL i2o s Network Monitoring accepts data from both i2o and third-party loggers and telemetry systems and presents a dashboard of information specifically designed to provide critical insights into network performance. Graphs and alarms highlight trends and exception conditions that facilitate timely and accurate decision-making for network management and optimisation. Designed to provide an easy to use, networkwide tool for day to day operations, Network Monitoring provides an important foundation for. It enables network managers to monitor and understand pressures and flows in the network. It ensures that pressure levels of service are being met and that PRVs and pumps are set correctly. It provides tools to monitor network flows and night flows and to identify bursts and areas of high leakage. It also provides intelligence and visibility into the opportunities for improving network performance through better pressure management and enables the results of pressure management strategies to be monitored and measured. Having identified areas of the network that would benefit from pressure management, Remote Control then allows operations staff to implement initial pressure management strategies in the network, without the need for site visits. Three types of pressure management scheme can be implemented with Remote Control: Basic Control The Basic Control option offers the user the ability to remotely set an outlet pressure on the PRV. Users can remotely increase or decrease pressures in a PMA or zone, informed by network monitoring software, in order to address leakage, change in demand, high burst rates or level of service issues. Pressures can also be changed across the whole network to take account of seasonal variations such as a freeze or drought. Timed Control This product builds on the functionality of Basic Control. Timed Control allows pressure changes to be made based on a 24-hour calendar schedule. Profiles can have 96 individual settings over 24 hours and can either be set manually or derived automatically from network data. Ideal for areas without flow meters, time-based control allows users to, for example, remotely set increased pressures during morning demand to ensure levels of service or reduce pressure at night to decrease leakage and bursts and optimise night flow. Flow Modulated Control This product builds on the functionality of Timed Control. Flow Modulated Control enables the PRV outlet pressure to vary as a function of flow rate. The pressure flow relationship is calculated and maintained manually by the user. Network Monitoring software showing spatial representation of network Remote Control configuration screen

7 The i2o Journey 11 Level 4 AUTOMATIC PRESSURE OPTIMISATION All of the pressure management strategies above rely on an experienced engineer to make a point in time assessment of the pressure control programme necessary for that PMA or zone. These skills are in short supply, which limits the scope of any pressure management programme. Networks also constantly change over time, ensuring that the effectiveness of any static control programme declines over time. i2o s Automatic PRV Pressure Optimisation and Automatic Pump Pressure Optimisation products overcome these limitations. They employ a patented, robust self-learning system that automatically and continuously controls pressure at the critical point. The system will learn the relationship between headloss, flow and time for a particular PMA or zone. It will then use that information to continuously adjust the inlet pressure to compensate for the headloss at any point in time in that PMA or zone. The system is able to deliver a stable, reliable target pressure at the critical point on an ongoing basis with no manual intervention. The level of precision of the control of pressure that this provides has been shown to be without equal in the industry. All of the i2o solutions for are built on the same enterpriseclass technology platform. This provides some important advantages over first generation solutions. Firstly it provides a consistent, easy to use interface that operations teams and pressure management specialists can use to have a shared, consistent view of the performance of the whole network. Everyone across the organisation who has an interest in understanding network data such as pressures and flows can see it quickly and easily in the context of the network structure and service levels that need to be delivered. Secondly, it allows for complete flexibility to deploy the right pressure management approach in each area of the network and the agility to change that quickly and easily as requirements change. A single technology platform means that the level of control for a particular PMA or zone can be easily upgraded or downgraded in a few clicks. So, for example, if you identify that a PMA would benefit from Automatic Optimisation rather than Remote Control, a licence can be applied for online and that functionality upgraded transparently within the system. Water utilities will no longer need to spend time and effort trying to theoretically analyse where different types of pressure management device should be deployed. With the new generation of technology you have one solution that can deliver all levels of control. Using the foundation of Network Monitoring means that you can ensure you know precisely where better control would be of value. i2o s Automatic Optimisation has made a huge difference, delivering stable criticial point pressure at peak and off-peak periods Melvin Engelbrecht, Chief Technician, City of Cape Town Municipality Automatic PRV Optimisation configuration screen

8 The Benefits Of Smart Pressure Hundreds of installations around the world have generated a rapid return on investment from improved pressure management, based on six significant benefits: Leakage reduction - Pressures can be precisely controlled and set at the correct target level for the customer. With no excess pressure, leakage levels fall by an average of 20%. Energy savings - Less water being pumped at a lower average pressure leads to a significant reduction in energy consumption, usually in excess of 20%. Burst frequency reduction - Through lowering maximum pressures and smoothly controlling transitions, i2o customers regularly experience over 40% fewer bursts. Improved customer service - Target pressures can be delivered with a high degree of confidence; and because you can now detect and respond to issues more rapidly, there are fewer network related complaints. Extended asset lifetimes - Owing to the reduction in burst frequency, the lifespan of infrastructure approaching replacement can be extended, typically by 5 years or more. Operational cost savings - i2o customers save money from 40% less find and fix activity and fewer scheduled site visits. Conservatively speaking, we estimate that the i2o Water solution will extend the life of our existing infrastructure and assets by five to ten years or more.
