This document is applicable to the trenchless construction, trenchless replacement techniques and testing of new drains and new sewers in the ground and usually operating as gravity or pressure pipelines, formed using prefabricated pipes and their joints.
Renovation techniques for existing pressure and non-pressure systems are not covered by this document.
Methods of trenchless construction include:
- manned and unmanned techniques;
- steerable and non-steerable techniques.
Requirements for associated pipeline installation work other than trenchless construction, e.g. for manholes and inspection chambers, are not covered by this document and are specified in EN 1610. This also applies to pipes that are subsequently installed within entry and exit shafts/pits.
