European foreword
This document (prEN 17670-1:2021) has been prepared by Technical Committee CEN/TC 155
“Plastics piping systems and ducting systems”, the secretariat of which is held by NEN.
This document is currently submitted to the CEN Enquiry.
This document is a supplementary standard for System Standards for plastics piping systems of
a particular material for a specified application. There are a number of such System Standards.
System Standards are based on the results of the work being undertaken in ISO/TC 138 “Plastics
pipes, fittings and valves for the transport of fluids”, which is a Technical Committee of the
International Organization for Standardization (ISO).
They are supported by separate standards on test methods, to which references are made
throughout the System Standard.
Product complying with this standard are intended for use in storm water systems.
This document does not cover pump chambers.
The System Standards are consistent with general standards on functional requirements and on
recommended practice for installation.
EN 17670 consists of the following parts under the general title 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 polyvinyl chloride (PVC-
U), polypropylene (PP) and polyethylene (PE):
— Part 1: Specifications for storm water manholes and inspection chambers (this document);
— Part 2: Specifications for storm water road gullies (under development);
— Part 3: Assessment of conformity (CEN/TS to be developed).

Introduction
The products covered by this standard are intended for use as part of storm (surface) water
management systems such as:
— transport of storm/surface water;
— road drainage;
— land drainage;
— infiltration;
— attenuation and storage.
1 Scope
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.

When testing for the durability of compound/formulation at higher temperatures, plates welded to both ends
of the telescopic adaptor may be used to seal the connections. The test assembly should be sufficient to avoid
contact between the plates during the test.
5.6 Use of reworked material and recyclates
Reworked material and recyclates may be used up to 100 %. For the utilization of reworked
material and recyclates, conditions and requirements are given in Annex D.
5.7 Sealing ring retaining components
It is permitted that sealing rings are retained using means made from polymers other than PVC-
U, PP or PE.
6 General characteristics
6.1 Appearance
When viewed without magnification, the internal and external surfaces of SWMH or SWIC shall
be smooth, clean and free from defects likely to prevent conformity with this standard.
Pipe ends or spigots shall be cleanly cut and square with their axis.
6.2 Colour
Any colour may be used.
7 Geometrical characteristics
7.1 General
The diameter of the storm water riser shall be used to designate the nominal size of the SWMH
or SWIC.
NOTE Nominal size can be specified as DN/OD or DN/ID.
The manufacturer shall specify the relevant geometrical characteristics and the tolerances.
All dimensions shall be measured in accordance with EN ISO 3126.
7.2 Dimensions of SWMH and SWIC
7.2.1 SWMH
SWMH are for personnel access for maintenance works, cleaning and inspection.
The minimum dimensions of SWMH deviate per country and local circumstances and shall
therefore comply with the national regulations in force at the place of installation.
In the absence of national regulations, the diameter of the clear opening of the SWMH cover
according to EN 124 shall be ≥ 600 mm.
For a SWMH with circular section, the nominal inside diameter of the storm water riser shall
be ≥ 1 000 mm (see Figure 1).
NOTE 1 National or local safety - regulations or the relevant authority can specify larger minimum
dimensions e.g. for the access.
In specific circumstances, where national regulations allow, SWMH may have smaller dimensions.
In this case for a SWMH with circular section, the nominal inside diameter of the storm water
riser shall be ≥ 800 mm.
NOTE 2 For this type of SWMH special entry equipment (e.g.; harness and winch) is required.
7.2.2 SWIC
For an SWIC with circular section, the nominal inside diameter of the storm water riser shall
be ≥ 200 mm (see Figure 2).
7.3 Dimensions of base connections to pipework
The wall thickness of the spigot/socket for pipe connections shall not be less than those specified
either in EN 1401-1 or EN 13476 series.

their tolerances shall enable compatibility to pipe work in accordance with the product standards
of the pipes that they are intended to be connected to.
NOTE The requirement for wall thickness of the spigot/socket for pipe connections is not applicable
for riser to base assembly or sockets or spigots of risers, cones or telescopic adaptors.
7.4 Sand trap volume
When tested in accordance with Table 6 the sand trap volume (see Figures 1 and 2), shall meet
the requirements given in Table 6.

7.5 Geometrical characteristics of steps and ladders
7.5.1 General
SWMH can be provided with man entry equipment such as:
— steps;
— permanently fixed ladders (can be fitted either before or after installation);
— fixing provisions for ladders.
7.5.2 Steps
Plastics steps shall comply with the following requirements:
— these steps shall have a minimum width of step profile of 20 mm;
— these steps shall have a minimum width for single steps of 145 mm or for double steps a
minimum width of 250 mm;
— these steps shall have a minimum projection of 120 mm from the internal wall of the storm
water riser (see Figure 3 c));
— the vertical spacing within a finished structure shall relate to the internal height of the SWMH
and shall be within the range 250 mm to 350 mm (see Figure 3 c));
— single steps shall be fixed, with a tolerance of ± 10 mm, alternatively at centres in vertical
plan within the range 270 mm and 300 mm (see Figure 3 b));
— double steps shall be fixed vertically above each other (see Figure 3 a)).
Steps that are totally or partly manufactured from cast iron, steel or aluminium shall comply with
EN 13101.

7.5.3 Permanently fixed ladders
When a SWMH includes a fixed ladder, the ladder including fixing provisions, shall conform to the
requirements of EN 14396.
7.5.4 Fixing provisions for ladders
When a SWMH is supplied with fixing provisions for a ladder, these shall conform to the relevant
requirements of EN 14396.
8 Mechanical characteristics
When tested as detailed in Tables 7, 8 and 9, as applicable, the SWMH and SWIC shall conform to
the corresponding requirements.
