Abstract

This document provides more detailed and more technical background information relating to this topic of the sixth call for proposals under the specific programme for standards, measurements and testing (SMT), 1994-1998. The scientific and technical objectives are as follows:

- To define testing methods for the examination of existing sewers in-situ to assess the suitability for use of different rehabilitation techniques, taking into account:
. The results of previous research in different countries;
. The structural capacity and watertightness;
. The sensitivity of aquifers due to hydro-geological and other factors;

- The development of testing methods for the common evaluation of renovation methods:
. The durability or expected service lie in terms of chemical, biological and abrasive attack;
. The behaviour and charateristics including load bearing capacity of the pipe, and the rehabilitating material;
. Security of joints, their effective tightness and condition.
