Kilometers of pipe beneath the sand
Like with all important seaside resorts, the population number of the municipality Olonne alters considerably between winter and the holiday season. This asks for a made-to-measure sanitary solution which was really no longer the case. A massive project for the modernization of the sewage collector and wastewater treatment plant was therefore initiated beginning of 2003. The undertaking represents the largest sewer project launched on the French Atlantic Coast in 2005.

Manhole coating: an alternative renovation method?
For the renovation of manholes, coating methods are considered a competitive alternative to the renewal of the manhole. But are they really an alternative? So far there has hardly been evidence regarding limitations of use, influences on quality and the durability of the methods offered. The IKT has lightened the dark: in an extensive practical survey 42 manhole coatings were monitored and investigated at twelve sewage network operators.

How to drill clay
Why is it that while drilling in clay, the cuttings often swell and constrict the borehole rather than forming a good slurried flow? Unlike drilling in inert materials like rock or sand, many types of clay are reactive and once exposed to water and drilling fluid by reaming, their properties can change considerably. If you’ve experienced ground heaving, inadvertent flows (e.g., frac-out), reamer balling up and/or problems creating slurried flow using bentonite, chances are you’re drilling in clay.

GPR ? Finding our underground assets
GIGA was a 2 year, 3 month collaborative project supported by the European Commission’s 5th Framework Research Programme for Energy, Environment and Sustainable Development; it was completed in 2003. A team of Ground Penetrating Radar (GPR) experts, manufacturers and end-users combined to improve the technology used for metallic and non-metallic buried services infrastructure location. Fundamental research and development of existing technology was driven by a comprehensive set of end-user requirements. The technology resulting from GIGA was comprehensively tested under rigorous conditions on a purpose-designed site, and the performance data was analysed and evaluated by the independent team of end-users. Significant performance improvements over the then existing state-of-the art equipment were demonstrated, and areas of investigation for further enhancements were identified.

Are we approaching the universal shield?
For political and ecological reasons, the trenchless or underground construction method has become an essential part of establishing underground infrastructural supply and disposal networks in our cities. In the last decades, the major developments have focused on improving the machine technology with a view to create one machine type that alone is able to excavate the respective underground cavity independent of the geological and hydro-geological limiting conditions. The main focus of the following presentation is one shield machine type that may be seen as the forerunner of a universal shield.
