1. PM4WAT Preventive Maintenance for Water Utilities LEONARDO DA VINCI - Multilateral Project Development of Innovation Started in November 2009 Duration: 24 months PROWAT2 Meeting 23-24 March 2010 Thessaloniki, Greece

2. Maintenance is carried out only when a major breakdown (e.g. leak and a large volume of water) is observed. This is the most common policy used by urban water utilities today. The policy is time-consuming and costly as parts and components are often out of stock. Delays in procurement cause delays in restoration of service. Customer dissatisfaction is high and The integrity of the water utility is low. Traditional Maintenance

3. Preventive Maintenance Is the care and service of the network for the purpose of maintaining it in good operating condition. PM provides systematic inspection and detection of incipient failures and proactive rehabilitation i.e. before faults develop into catastrophic events. Requires systematic record keeping, tests and measurements for fault prognosis, parts ordering and work scheduling to minimise operational disruption and water loss.

4. Network Reliability Object is to preserve and enhance equipment reliability by replacing worn components (piping, connectors, joints etc.) before they fail. PM activities include scheduled branch inspection and partial replacements at regular intervals. Long-term benefits are reduced Life-Cycle Costs

5. The PM4WAT Project Fusion of national practices to produce –a unified curriculum definition and –a library of learning content for a multi-lingual web-based training course on Preventive Maintenance of Urban Water Utilities.

6. Project summary VET programme for urban water utility networks subject to: –ageing, –water losses, –seismic activity and –other natural hazards. Target group: –water utility personnel, –inspection engineers, –civil and hydraulic engineers

7. Project Objectives To provide urban water utility personnel training in PM that will lead to the adoption of state of the art practices offer training on pro-active rehabilitation and training on the effects of natural hazards.

8. Components of the VET The training program involves 2 components

9. a theoretical part which involves web- based courseware based on an e- learning platform (MOODLE) which provides embedded self-teaching and assessment capabilities.

10. and a practical part (based on an earlier FP5 project – SEISLINES) which involves software that integrates –GIS –Risk Analysis and –Database Management to estimate the temporal degradation of branches of the network for different environmental scenarios.

11. Scenario-Based Training The training program will use real data taken from a medium-sized urban water utility. The trainee will be able to examine the effects of different scenarios and learn the most appropriate rehabilitation procedures to use to rapidly mitigate any network problem.

12. 12 SEISLINES - Selection of network nodes Network nodes selection via GIS Selected nodes geometry Reliability calculation Selected nodes

13. 13 SEISLINES – Visualization of results Node Reliability curve over time Previous scenarios results stored in the database

14. 14 SEISLINES – Rehabilitation options Link (pipe) between two nodes Rehabili- tation options … based on the Reliability results
