BS EN 15885:2018 PDF Download

BS EN 15885:2018 is a European standard that provides a classification system for trenchless techniques used in the renovation, repair, and replacement of drains and sewers. It applies to both gravity and pressure-operated systems, including pipes, connections, and manholes. The standard defines different technique families and their generic methods and materials.

However, this standard does not cover replacement by open trenching or the construction and testing of new drains and sewers off-the-line of existing ones. It also does not specify requirements for specific products or address any work required on the existing pipe prior to renovation, repair, or replacement.

For each technique family, the standard lists relevant existing standards, materials, and applications, and provides information on installation aspects, structural and hydraulic capabilities, and site impact. The objective of this standard is to provide information to help determine suitable options and identify the optimal technique for a given set of renovation, repair, or replacement objectives.

It is important to note that the responsibility for choosing and designing the renovation, replacement, and repair systems lies with the designer. The standard does not provide calculation methods for determining the required material quantities to achieve the desired performance of the rehabilitated pipeline.
