What is PD CEN/TR 17179 - Rainwater infiltration and storage attenuation systems about?
PD CEN/TR 17179 applies to the installation of rainwater infiltration and storage/attenuation systems under gravity.
PD CEN/TR 17179 covers installations including:
- Reservoirs made by assembled cuboid-shaped thermoplastic boxes
- Integral components
- Ancillary components (e.g. Access provisions and connections)
- Geotextiles and/or geomembranes
- Embedment and backfill
These systems are intended for underground use in landscape, pedestrian or vehicular traffic areas and are used outside building structures.
PD CEN/TR 17179 is only applicable to systems containing boxes to create a reservoir where the manufacturer has clearly stated in the installation instructions how the components should be assembled.
PD CEN/TR 17179 is a guidance document. It provides a set of general guidelines which give best practices for installation.
NOTE 1: It is anticipated that additional recommendations and/or requirements (e.g. design, dimensioning and structural aspects) will be detailed in the relevant standards.
NOTE 2: Attention is drawn to the need to comply with national or local regulations.
Who is PD CEN/TR 17179 - Rainwater infiltration and storage attenuation systems for?
PD CEN/TR 17179 on thermoplastics piping and ducting systems is relevant to:
- Local authorities
- Design engineers
- Installation contractors of rainwater infiltration and storage attenuation systems
- Manufacturers rainwater infiltration and storage attenuation systems
Why should you use PD CEN/TR 17179 - Rainwater infiltration and storage attenuation systems?
Rainwater harvesting, infiltration, and decentralized retention of rainwater (attenuation) are examples of ecological and sustainable rainwater management. Excess water from rainwater harvesting systems should be infiltrated into the ground or released in a controlled manner into surface water bodies.
PD CEN/TR 17179 contains guidance for installation procedures for thermoplastic infiltration and attenuation systems outside building structures, which should be completed in conjunction with product-specific installation instructions.
PD CEN/TR 17179 is a guidance document. PD CEN/TR 17179 provides a set of general guidelines which give best practices for underground installation of thermoplastic infiltration and attenuation systems outside building structures.
PD CEN/TR 17179 includes recommendations for the reservoir surround and backfilling procedures but not road base and road sub-base details. Attention is drawn to any national regulations which may cover these or other aspects of the installation.
In this PD CEN/TR 1717, much of the guidance is expressed as requirements, e.g. by use of “shall” or by instructions in the imperative. It is strongly recommended that these be followed whenever applicable.
