1. Technology that optimises water distribution networks
2. The importance of optimisingwater pressure
3. PRESSURE MANAGEMENT CHALLENGE
4. BASIC PRESSURE MANAGEMENT Fixing pressure at the PRV outlet Leads to excessive pressure 100% of the time at critical point Potential response: basic time & flow modulation Weak control of pressure vs target Inability to respond and adapt to changing network circumstances
5. ADVANCED PRESSURE MANAGEMENT Total visibility into network performance Remote management of pressure Automatically and continuously optimised pressure based on demand patterns Delivers the right pressure (and no more) in the network all the time

14. i2O SYSTEM – PRV CONTROL components Controller Logs pressure and flows with high accuracy GPRS and Bluetooth communication Low power consumption – 5 year battery life Robust, waterproof enclosure APV (Advanced Pilot Valve) Accurate control over 32m range Smooth preassure change – no surge Any PRV Critical Point Logger Logs pressure with high accuracy GPRS and Bluetooth communication Low power consumption – 5 year battery life Robust, waterproof enclosure
15. i2O SYSTEM – SOFTWARE INTERFACE Secure Integrated system – see data and act on it Scalable throughout the business Quick and easy to implement Cost effective
16. i2O SYSTEM – NETWORK MONITORING
17. ADVANCED PRESSURE MANAGEMENT Remote pressure optimisation Remote diagnostics Quick DMA set-up and installation Scheduled pressure control Scheduled alarm control
18. i2O – Worked Example : Implementation Flow (l/s)/Pressure (m) Time
19. LEAKAGEREDUCTION Syabas: 35.4 MLD reduction in 178 DMAs Each percentage point of pressure reduction in a water network leads to a corresponding decrease in leakage i2O’s solutions have reduced leakage by 10 to 50% in hundreds of water networks.
20. BURSTFREQUENCYREDUCTION Veolia Water UK installation Minimizing pressure peaks and softening fluctuations reduces the frequency of bursts i2O’s solutions havereduced burst frequencyby 40% or more in customers’ water networks. After i2O Before i2O
21. LOWEROPERATINGCOSTS Remote monitoring gives managers visibility to network performance and events from any online connection or location Remote PRV control eliminates site visits to adjust PRVs manually Reduced leakage and bursts decrease need for ‘find and fix’ activity Early detection of asset degradation reduces need for routine maintenance visits
22. IMPROVEDCUSTOMERSERVICE LEVELS Many water networks’ service levels suffer during peak demand, leading to complaints and fines. i2O’s solutions maintain the right pressure, without abrupt changes, minimising customer service problems.
23. ENERGYSAVINGS APA Nova Ploiesti (Romania) installation The lower the water pressure you supply to a network, the lower your energy consumption Installed on pumps with variable speed drives, Advanced Pressure Management from i2O can reduce energy consumption by more than 20%
24. EXTENDEDMainsLIFETIMES Many water networks are at or near their service lifetimes Burst frequency is the key trigger for capital-intensive pipe replacement investments Reduced burst frequency significantly extends pipe lifetimes
25. i2O WORLDWIDE 900+ systems installed in 40 utilities in 21 countries
26. i2O Malaysia 3 systems 1.21 Ml/d 8 systems 2.78 Ml/d 4 systems 10.36 Ml/d 6 systems 3.59 Ml/d Logging in progress 1 system + 3 reservoir sensors 229 systems 51.36 Ml/d Total 251 systems Saving 69.5 Ml/d
27. IMPLEMENTING i2O SOLUTIONS IN Malaysia Advanced Pressure Management technology is quick to implement: Under 2 hours Rapid NRW reduction: Over 69 Ml/d Deferred capital expenditure needed for new water plant Average payback for Malaysian Water Companies: 5 months
28. Advanced Pressure Management Examples SYABAS Largest water concessionaire in Malaysia (supplies 7 million consumers) Cut leakage by 40 million litres per day Reduced burst frequency by 48% Expanded Advanced Pressure Management from 50 to 100 to 200 installations over 2 years
29. Advanced Pressure Management Examples Manila Water Serves more than 6 million consumers in Manila, Philippines 10 MLD pump station cut energy consumption 24% on weekends,14% on weekdays Cut network leakage by 800,000 litres per day on weekends, 500,000 liters per day on weekdays Radically improved level of service from network pumps (failed dailyprior to i2O installation)
30. Advanced Pressure Management Examples Veolia Water Provides water and wastewater services throughout the UK Achieved savings on operational costs of 80% Improved customer service Reduced water loss from eight “problem DMAs” by more than1.5 MLD
31. Advanced Pressure Management Examples Number of mains repairs (per thousand properties) identified by type of pressure management During the two last years the number of mains repairs was reduced by nearly 75% in DMAs equipped with i2O systems.
32. Advanced Pressure Management Examples NWC and Jeddah City Business Unit (JCBU) Advanced Pressure Management pilot on two District Zones Systems installed and optimised in 2 days 20% pressure reduction 10% leakage savings 40% reduction in pipe bursts Remote control capability improved efficiency Enhanced benefits for District Zones with continuous supply
33. Advanced Pressure Management Examples NWC and Jeddah City Business Unit (JCBU) Change from a fixed PRV outlet to a flow modulated pressure within the Zone Pressure is stabilized at critical point inside the Zone
34. Proven return on investment i2O customers typically achieve ROI within 6-12 months
