21/30425785 DC


This standard 21/30425785 DC BS EN 17670-1. Plastics piping systems for non-pressure underground conveyance and storage of non-potable water. Manholes, inspection chambers and road gullies for storm water systems made of unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP) and polyethylene (PE) is classified in these ICS categories:
  • 23.040.20 Plastics pipes
  • 93.030 External sewage systems

This document specifies the definitions and requirements for unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) storm water manholes and storm water inspection chambers intended for non-pressure use only in storm water systems to a maximum depth of 6 m from ground level to the lowest point of the storm water manhole or inspection chamber.

NOTE 1

Products complying with EN 13598‑2 can also be used for storm water systems dependent on the requirement of the storm water system.

Storm water manholes and inspection chambers complying with this document are intended to be used in pedestrian or vehicular traffic areas outside the building structure.

NOTE 2

Products complying with this document can also be used in non-traffic areas.

Storm water manholes and inspection chambers complying with this document are made from a prescribed set of components that are manufactured from unplasticized poly(vinyl chloride) (PVC-U), polypropylene (PP), polypropylene with mineral modifier (PP-MD) or polyethylene (PE) and assembled together.

Storm water manholes and inspection chambers complying with this document may be equipped with optional devices (e.g. removable sand or silt bucket, flow regulators, ventilation parts, etc.), however the performance of these optional devices is not covered within the scope of this document.

NOTE 3

Products complying with this standard can be installed in underground applications without additional static calculation.

NOTE 4

The complete storm water manhole or inspection chamber assembly can also include items which are not covered by this document (for example near surface or surface components).

NOTE 5

Storm water manholes and inspection chambers can be supplied with covers, frame covers and gratings complying with the relevant part of EN 124 [1].

Storm water manhole and inspection chamber components can be manufactured by various methods e.g. extrusion, injection moulding, rotational moulding, low-pressure moulding or fabricated.

NOTE 6

Storm water manholes and inspection chambers can be site assembled from different components, but can also be manufactured as a single unit.

NOTE 7

Storm water manholes and inspection chambers can be subject to national regulations and / or local provisions.
