CEN/TC 155/WG 26 - Storm Water Management
Storm Water Management
General Information
This document gives guidance on the structural design of underground modular systems for infiltration, attenuation and storage of surface water under various conditions of loading. The procedures are explained, with the appropriate variables in the design formulae, and provides graphical information on vehicle surcharge loadings.
These modular systems are constructed from multiple cuboid shaped thermoplastic boxes generally with ancillary components such as inlet/outlet connectors, vents, and access/inspection provision. This guidance is for the design of modular systems conforming to EN 17152-1.
The boxes, including integral components, are injection moulded, extruded or thermoformed thermoplastics, manufactured from polypropylene (PP) or unplasticized poly(vinyl chloride) (PVC-U), and are intended to be used as elements in a modular system where the manufacturer has clearly stated in the documentation how the components are assembled to create a complete infiltration, attenuation or storage system.
Outside the scope of this document are the following conditions:
- seismic loads,
- lateral loads from adjacent structures and embankments,
- influence of trees,
- backfill materials not according to CEN/TR 17179 [1].
Geotextile and/or geomembrane used with modular systems are outside the scope of this document.
NOTE If reference is made in this document to Eurocode standards, the conditions in a national foreword or national annex are normally stated.

This document gives guidance for requirements for the assessment of conformity (AoC) of materials, compounds, formulations, products, and assemblies in accordance with the applicable part(s) of EN 17152 intended to be included in the manufacturer’s quality plan as part of the quality management system and for the establishment of certification procedures.
NOTE Annex B, Table B.1 contains a summary of tests for TT and surveillance monitoring.
In conjunction with EN 17152 1 (see European foreword) this document is applicable to boxes used for infiltration, attenuation and storage systems.

This document specifies a test method for determining the long-term compression strength for a specified period on boxes made of thermoplastics materials for non-pressure underground conveyance and storage of non-potable water.
The document is applicable for boxes which maintain their linear behaviour over the specified period.

This document gives the definitions and specifies the minimum requirements for injection moulded, extruded and thermoformed thermoplastics cuboid shaped boxes, including integral components, used in underground systems for infiltration, attenuation and storage of non-potable water (e.g. storm water) and manufactured from unplasticized poly(vinyl chloride) (PVC-U) or polypropylene (PP).
NOTE 1 Specifications and design rules for systems (water reservoir) are described in part 2 of EN 17152.
Product properties are determined by a combination of material specifications, design and manufacturing process.
These boxes are intended for buried underground use, e.g. in landscape, pedestrian or vehicular traffic areas.
A box can either be factory assembled or site assembled from different components.
These boxes are intended to be used as elements in a modular system where the manufacturer has clearly stated in the documentation how the components are assembled to create a complete infiltration, attenuation or storage construction.
NOTE 2 Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, thermoforming and low-pressure injection moulding.
