4 Computer aided rehabilitation strategy for supply pipeline systems ´ on basis the pipe groups and pipe sections

5 Computer aided rehabilitation strategy for supply pipeline systems G I S - Database pipe data – damage data – graphical data Pipe groups Existing pipe analysis Damage analysis Damage prognosis Replacement rate–50 years Pipe sections + graph Damage rate-pipe section Damage prognosis External criteria register Pipe replacement / year Selection for rehabilitation Rehabilitation method pipe material rehabilitation criteria economic aspects Step 1 Step 2 Step 3 Infr.Pro Infra.Plan Infra.Reha

6 Damage dataPipe dataNetwork grafic Infra.stat Damage analyse Damage prognose Infra.Pro Rehabilitation rate Strategies Infra.Plan Network rehabilitation p.a. Infra.Plan Detail planing in the street Hydraulic network simulation for actual diameter GIS 6 steps for rehabilitation of pipes Damage analyse Rehabilitation strategy Rehabilitation priorities Detail planing for one pipe Hydraulich network analyse for actual diameter Pipe groupesPipe sections Leitungsbestand Infra- System

9 Rehabilitation concept for rehabilitation needs on the basis of pipe groups Kohorten- Pipe life model I N F R A Calculating of the operation time Rehabilitation- options Network Damage data Network Pipe data Cost of the projects Network simulation for future planing Network simulation Existing situation Results: Quantity of renewal Limited operation time Damage development Actual pipe data Rehabilitation costs

10 Analysis of the existing pipe data Pipe groups and construction period

11 Underground Pipe material Number of service pipes Age of the pipe Pipe connections Isolating of the pipe Traffic in the street Influences of construction works Quality of pipe construction Operation pressure of the medium Influences of damages

12 Damage rate on miansDamages on service pipes Diameters in mmMaterials Analysis of the damage data over a longer period Damage development over 17 years

13 Examples Analysis of the damage data over a longer period Damage analyse for Steel pipe group Damage analyse for cast iron pipe group

14 Prognosis simulation of existing pipegroups Concentration of damages on basis the age of pipes Determine of the critical damage rate and the risc range of pipes Determination of the forecasted age with standard tolerance

15 Evaluated service time and residual service life of all pipe groups

16 Survial function Failure rate Distribution of the age Residual service life Determine of the ageing function of one type of pipes Age of the pipe Residual service life in years

17 Future rehabilitation needs Evaluated by Infra.Pro

18 Existing rehabilitation activities and forecated future rehabilitation needs Future rehabilitation needs 0,5% 1,0% 1,5% 2,0%

19 Computer aided selection of efficient rehabilitation projects on the basis og pipe sections Evaluated by infra.plan Criteria catalog of infuences for rehabilitation projects Presentation of results in GIS

20 Determination of pipe sections for rehabilitation Evaluation by Infra.Plan with GIS-data

21 Numeric data presentation of the pipe sections needed for rehabilitation

22 Methods for the rehabilitation of pipelines Rehabilitation of pipesRenewal of pipes Tube reliningCement relining Pipe construction Closed replacement PE-Lining Closed lining Berst-lining Press-pull-lining Repair campaignsRehabilitation Cleaning of pipes Maintenance
