Overview

FprEN 17152-1: Plastics piping systems for non-pressure underground conveyance and storage of surface water specifies the minimum requirements for cuboid-shaped thermoplastic boxes made of polypropylene (PP) and unplasticized polyvinyl chloride (PVC-U). These boxes are designed for use in modular underground systems for infiltration, attenuation, and storage of surface water such as stormwater. The standard, developed by CEN/TC 155, also defines key terms, general characteristics, and the necessary product documentation for these systems.

This European standard targets manufacturers and suppliers of plastics piping systems, civil engineering professionals, and municipal authorities implementing sustainable surface water management solutions. It aims to ensure durability, reliable performance, and interoperability of thermoplastic boxes regardless of manufacturing method (injection molding, extrusion, or thermoforming).

Key Topics

• Material Requirements: The document establishes requirements for using PP or PVC-U, which may include specified additives or minerals, and lays out rules regarding the use of virgin, reworked, or recycled materials.
• Design and Assembly: Boxes can be factory-assembled or site-assembled and must be suitable for modular construction, as defined by the manufacturer’s documentation.
• Product Characteristics:
  • Dimensional tolerances, porosity, and color
  • Mechanical properties, including short-term and long-term compression strength
  • Physical properties for injection molded units, such as resistance to heating and delamination
• Testing and Compliance: The standard references test methods for verifying mechanical and physical characteristics, including resistance to internal pressure, creep behavior, and sensitivity to non-rigid loading.
• Documentation & Marking: Manufacturers must provide clear information about materials, intended use, mechanical properties, porosity, and assembly instructions. Durable marking on boxes is mandatory for traceability.

Applications

FprEN 17152-1 boxes are widely used in various fields of urban and rural surface water management, including:

• Stormwater Infiltration and Storage: These boxes form the core components of modular infiltration and attenuation systems, allowing controlled recharge of groundwater or temporary storage of excess surface water.
• Landscape and Urban Projects: Suitable for installation under green areas, pedestrian walkways, and vehicular traffic zones due to stringent mechanical strength requirements.
• Sustainable Drainage Systems (SuDS): The standard supports the design of modular tanks for rainwater harvesting, reducing peak flow rates and mitigating flooding risks.
• Infrastructure Modernization: Municipalities and land developers use these systems as an alternative or complement to traditional drainage networks.

The modular design and comprehensive marking requirements ensure that these systems can be flexibly integrated, assembled, and maintained according to local regulations and project specifications.

— subclause 10.2 improved with more information;
— editorial improvements through the document.
This standard is supported by separate standards on test methods to which normative references are
made.
EN 17152-series consists of the following parts under the general title Plastics piping systems for non-
pressure underground conveyance and storage of surface water - Boxes used for infiltration, attenuation
and storage systems:
— Part 1: Specifications for boxes made of PP and PVC-U [this document];
— Part 3: Assessment of conformity (CEN/TS);

Introduction
The products covered by this document are part of surface water management system.
This document is intended to reflect the current state of knowledge of determining and predicting the
long-term lifetime of product groups mentioned in the scope while maintaining reasonable testing times
for producers and developers of these systems.

1 Scope
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 surface water (e.g. storm water) and
manufactured from polypropylene (PP) or unplasticized polyvinylchloride (PVC-U).
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 states in
the documentation how the components are assembled to create a complete infiltration, attenuation or
storage system.
NOTE Non load bearing component(s) can be manufactured by various methods e.g. extrusion, injection
moulding, rotational moulding, thermoforming and low-pressure injection moulding.
