3. DST & DMS Overview TILDEDST • Tilde DST or Decision Support Tool • Guides the user through theleakage management process • Provides an integrated set of process maps for leakage management • Contains Best Practice guidance on how to manage and reduce leakage in the water network • Is suitable for a range of network configurations • Provides a record of decisions made for each leakage project • Provides links to a technology database and the TILDE DMS

4. DST & DMS Overview Tilde Best Practice & Technology Databases These provide additional information for the user on latest best practice and technology information. The databases are held within the TILDE web portal (www.webportal.com) and can be accessed via the DST. Technologies included are: Acoustic location, Gas tracer systems, Ground probing radar, In-pipe methods, Pressure and flow monitoring, Water quality monitoring, Geographic mapping and Network modelling.

5. DST & DMS Overview • Tilde DMS or Data Management System • Manages water network data from: • flow meters • pressure meters • acoustic devices • Records and reports information on: • leaks • leakage detection activities • repairs • Analyses: • flow data for prioritizing zones TILDEDMS

6. TILDE DST • Tilde DST or Decision Support Tool • Access different areas of best practice • Store project information • Recall saved project information

7. TILDE DST Process Maps • Tilde DST or Decision Support Tool • Navigate via the process maps or drop down menus to areas of interest • Select direct access to Best Practice, or • Follow the decision support system

9. TILDE Data Management System (DMS) • Tilde DMS or Data Management Tool • Stand alone product, or access via DST • Allows the user to input flow, pressure and acoustic data • Produce leak detection, location and repair reports • Rank zones in order of priority for leakage activity targeting Main menu of TILDE DMS v1.15

10. DMS Flow / pressure meter database • Import your flow/pressure data from your various data sources into a central management system • Use further information to specify the location of your meters • Visualize the recorded flow/pressure data

11. DMS Customer leak report • Record customers complaints and observations • Manage customer leak reports in conjunction with your leak location exercises

12. DMS Leak location report • Follow up and record all leak location exercises • Provide your staff with working forms to fill in • Collect data related to your leaks useful for further analysis • Create statistics of your leak location exercises

13. DMS Leak repair report • Make records of your leak repairs • Provide your staff with site forms to record data • Create statistics of your leak repairs

14. DMS Prioritisation of zones • Ranking of zones for further ALC measures • Based on ‘measured’ against ‘estimated’ minimum night flow • Zone ranking dependent on actual leakage against background level, costs for water and leakage location exercises and time since last survey
