Trenchless Pilot Program

Trenchless Pilot Program

showcase1The ‘Trenchless Pilot Program’, funded by the Embassy of the Kingdom of the Netherlands, was successfully carried out within EWS under guidance of Your Man on Site (YMoS), over the last two years. With the assistance of program partners and BAM Nelis Infra, the program has tested different trenchless technologies under local circumstances, addressing cost effectiveness, knowledge transfer, capacity building and feasibility. The program was tailored to the needs of EWS within the asbestos cement (AC) water mains replacement program and focused on ‘Close Fit’ rehabilitation technologies as well as pipe cracking.3product specification

Background

From 2010 to 2012 the ‘Trenchless Pilot Program’, funded by the Embassy of the Kingdom of the Netherlands, was successfully carried out within EWS under guidance of Your Man on Site (YMoS). With the assistance of program partners WAVIN (the leading supplier of plastic pipe systems and solutions in Europe) and BAM Nelis Infra (specialist in underground pipeline constructions for water & sanitation infrastructure), the program has tested different trenchless technologies under local circumstances, addressing cost effectiveness, knowledge transfer, capacity building and feasibility.

The program was tailored to the needs of EWS within the asbestos cement (AC) water mains replacement program. It focused on ‘Close Fit’ rehabilitation technologies (e.g. WAVIN’s Compact Pipe and Neo Fit for the rehabilitation of respectively mains and service connections).

Technology

image009.jpgVia the installations EWS gained insight into the high socio-economic inconvenience caused by conventional 'open trench' utility work as experienced by its customers.

‘Know how’ was developed to assist decision-making on installation techniques and material, related to local (urban) circumstances.

EWS gained access to new innovative ‘Close Fit’ lining rehabilitation technologies of Dutch origin and a pool of licensed and trained local contractors.

Status & Feedback

The showcase has been concluded in 2013.

Results

image013The tested trenchless technologies provide a superior solution in terms of social and environmental costs. When replacing a pipeline under the correct conditions it also scores positive when comparing direct costs.

  • The ‘Trenchless Pilot Program’ proved to be an effective method to facilitate the launch of new trenchless technologies for the benefit of South Africa and EWS.
  • Several national contractors have invested in the necessary equipment and are licensed by WAVIN with the tested ‘Close Fit’ technologies.
  • Other South African municipalities have now awarded rehabilitation contracts with these Dutch trenchless technologies.
  • These trenchless technologies might well be a feasible way of cost effectively speeding up municipalities rehabilitation of water & sanitation infrastructure.

Generic specifications to guide non-biased tender processes were developed.

A supportive trenchless decision model is available.

Training

A training is available addressing the following points;

  • Rehabilitation: reasons & Approaches
  • Socio economics of Trenchless Technologies
  • Comprehensive overview on different Trenchless Technologies
  • Decision modelling, which technology to use where
  • Generic specifications
