2 How to select the best rehabilitation option? 2 No no My solution is perfect for you!

3 How to select 3

4 How to select 4 Need for means of comparison

5 Design Approach Pipeline Rehabilitation Select the least cost solution 3 3. Check capabilities of offered Techniques 2 2. Set requirement for the new Pipeline 1 1. Assess the performance of the existing Pipeline

6 Design Approach Sewer Rehabilitation 6 1 EN Conditions of drain and sewer systems 2003

10 Design Approach Sewer Rehabilitation 10 4 EN ISO / EN Classification & Characteristics 3 EN ISO ,3,4 Product standards (e.g. CIPP/Sewer) 2 EN Gen.requirements for renovation and repair of drain and sewer systems 1 EN Conditions of drain and sewer systems

11 International Standardisation History : ISO establish a working group for pipeline rehabilitation ISO / TC138 / WG12 Rehabilitation with plastics pipes and their constituents 1992: after publication of technical report ISO/TR working group put on hold because of parallel work going on in CEN (Europe)

12 International Standardisation History : ISO establish a working group for pipeline rehabilitation ISO / TC138 / WG12 Rehabilitation with plastics pipes and their constituents 1992: CEN took over the work CEN / TC155 / WG17 Organisation: WG 17: convenor Wim Elzink (since +/- 2002) TG 1: general guidance TG 2: sewer general TG 3: water pressure. TG 13: close-fit pipes TG 16: cured-in-place pipes always active DK representation: Inge Faldager, Per Romdal, Peter Lystbæk, Flemming Springborg,

13 International Standardisation History : ISO establish a working group for pipeline rehabilitation ISO / TC138 / WG12 Rehabilitation with plastics pipes and their constituents 1992: CEN took over the work CEN / TC155 / WG : European standards published: EN 13689: Classification & Design guidance EN 13566: Non-pressure Sewer standards EN 14409: Water pressure standards EN 14408: Gas pressure standards

14 Standards structure CEN/TC 155/WG CEN/TC 155/WG 17 Renovation with plastics pipes Each of the System Standards comprises a: Part 1: General and all applicable renovation technique family related parts from the following list: Part 2: Lining with continuous pipes Part 3: Lining with close-fit pipes Part 4: Lining with cured-in-place pipes Part 5: Lining with discrete pipes Part 6: Lining with inserted hoses Part 7: Lining with spirally-wound pipes

15 CEN/TC : Request for standardising an additional (non-plastics) technique family: 2004: CEN/TC 165 established WG 13 only for sewer applications Organisation: WG 13: convenor secretary Renovation and Repair of Drains and Sewers J.Brünecker H.J. Kropf, DIN 2010: EN Classification and characteristics of techniques for rehabilitation of drains and sewers incl. Repair techniques and Non-plastics materials 2013: Draft EN. Systems for renovation of drains and sewers - Lining with a rigidly anchored plastics inner layer (RAPL)

16 Meanwhile here in Denmark : The Danish Quality Control Scheme for Pipeline Rehabilitation was founded Ensuring that contract work performed complies with: the quality manual of the company the declaration of the rehabilitation system in question The Control Scheme, currently only underground non-pressure drainage and sewerage networks, comprises: Renovation by lining with Cured-in-place pipes Renovation by lining with Close-fit pipes Replacement by Pipe bursting

17 ISO awake again : ISO establish a working group for pipeline rehabilitation ISO / TC138 / WG12 Rehabilitation with plastics pipes and their constituents 1992: after publication of technical report ISO/TR working group put on hold because of parallel work going on in CEN (Europe) 2002: WG12 re-activated to bring the CEN standards to ISO level time to wake up! 2010: ISO Classification and information on design of plastics piping systems used for renovation.

18 ISO 11295: Definitions 18 rehabilitation all measures for restoring or upgrading the performance of an existing pipeline system renovation work incorporating all or part of the original fabric of the pipeline by means of which its current performance is improved replacement rehabilitation of an existing pipeline system by the installation of a new pipeline system, without incorporating the original fabric technique family group of renovation techniques which are considered to have common characteristics for standardisation purposes

19 ISO 11295: Classification of Rehabilitation Techniques 19 Rehabilitation Maintenance & Repair Renovation Replacement Cleaning Coating Open cut replacement Joint repair Lining Continuous pipes Cured-in-place pipes Close-fit pipes Spirally-wound pipes Tr.less replacement Pipe bursting

21 ISO 11295: Structural Classification Pressure pipe liners 21 Not standardized

22 International Standardisation History 22 from 2009 onwards: ISO EN ISO EN Classification and information on Design of plastics piping systems used for Renovation ISO EN ISO EN Plastics piping systems for renovation of underground Non-pressure drainage and Sewerage networks ISO EN ISO EN Plastics piping systems for renovation of underground water supply networks ISO EN ISO EN Plastics piping systems for renovation of underground gas supply networks ISO EN ISO (being published soon) Plastics piping systems for renovation of underground drainage and Sewerage networks under Pressure

23 1 st Typicality of Renovation standards 23 Testmethods and Requirements laid down in specific standards drafted by CEN/TC 155/WG 17 o Lining pipes shall conform to requirements of regular pipes o Lining pipes generally undergo changes at installation. Testing of lining pipes in their installed state

24 Quality Assurance of Liners 24 M stage stage as manufactured, before any subsequent site processing of components examples I stage stage as installed, in final configuration after any site processing of components

25 Examples Testing of Manufactured Liner 25 MFI OIT Memory test

33 CONCLUDING REMARKS 33 Trenchless renovation is a maturing market supported by international standards ISO standards for pipeline renovation available Renovation is an application in which plastics have demonstrated their versatility Challenges different from those of direct-bury pipe Required testing of products in the installed state assures quality of the new pipeline
