Thermoplastics piping and ducting systems - Outside the building structures for gravity and pressurised systems - Trench installation
This document gives the recommended practise for underground open trench installation and commissioning of thermoplastics piping systems to be used for the conveyance of water under pressure (in addition to EN 805) and for the discharge of wastewater under gravity (in addition to EN 1610) .
In the field of non-pressure underground drainage and sewerage this is reflected in the marking of products by application code "U" and "UD":
- outside the building structure (U);
- both buried in ground within the building structure (application area code "D") and outside the
building (application area code "UD").
This document covers also installation and/or connections to valves, manholes, inspection chambers, gullies and other ancillary components in piping systems.
NOTE 1 Code of practise for pipelines for gas supply is covered by EN 12007-series [21].
NOTE 2 Recommended practices for installation of plastic piping systems for soil and waste discharge within the building structure is covered by CEN/TR 13801 [12].
NOTE 3 Practices for underground installation of rainwater infiltration and storage attenuation systems are covered by CEN/TR 17179 [13].
NOTE 4 It is assumed that additional recommendations and/or requirements are detailed in the individual product standards.
NOTE 5 If non-plastic components are part of the plastic system the manufacturer's instructions should be taken into account.
Requirements and instructions concerning commissioning of systems can be found in EN 805 and EN 1610 and the relevant national and/or local regulations. This document gives specific additional recommendations for commissioning relevant for plastic piping systems.
Attention is drawn to any relevant local and/or national regulations (e.g. health, safety and hygienic requirements).

European foreword
This document (CEN/TS 1046:2021) has been prepared by Technical Committee CEN/TC 155 “Plastics
piping systems and ducting systems”, the secretariat of which is held by NEN.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes CEN/TR 1046:2013.
This document is changed fundamentally by taking out design topics and topics already dealt with in
EN 1610 and EN 805. The lay-out was changed and the pressure systems are described more in detail.
According to the CEN/CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to announce this Technical Specification: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland,
Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of
North Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the
United Kingdom.
Introduction
This document contains guidance for installation procedures for thermoplastics piping systems and
their components intended to be used below ground for pressure and non-pressure applications
outside building structures. This document is intended to be used in conjunction with general standards
for installation recommendations, for example those issued by CEN/TC 164 “Water supply” and
CEN/TC 165 “Waste water engineering” as stated in EN 805 and EN 1610 respectively.
NOTE 1 Guidelines for installation of pipelines made out of thermosetting materials can be found in the ISO/TS
10465 series [23].
This document is based on the results from research with full-scale trials undertaken by the
thermoplastics pipes industry and expressed in CEN/TS 15223.
This document is a guidance document only. It provides a set of general guidelines which gives best
practices for underground installation of thermoplastics piping and ducting systems outside building
structures.
This document includes recommendations for the pipe 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.
This document does not cover matters relating to renovation of existing pipeline systems using lining
techniques, or replacement of existing pipeline systems using trenchless techniques.
NOTE 2 Guidelines for installation of lining techniques can be found in the EN 12889 series
This document is intended to be used by authorities, design engineers, installation contractors and
manufacturers.
In this document, 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.
Other guidance is presented for consideration as a matter of judgement in each case, e.g. by use of
“should”.
1 Scope
This document gives the recommended practise for underground open trench installation and
commissioning of thermoplastics piping systems to be used for the conveyance of water under pressure
(in addition to EN 805) and for the discharge of wastewater under gravity (in addition to EN 1610).
In the field of non-pressure underground drainage and sewerage this is reflected in the marking of
products by application code “U” and “UD”:
— outside the building structure (U);
— both buried in ground within the building structure (application area code “D”) and outside the
building (application area code “UD”).
This document covers also installation and/or connections to valves, manholes, inspection chambers,
gullies and other ancillary components in piping systems.
NOTE 1 Code of practise for pipelines for gas supply is covered by EN 12007-series [21].
NOTE 2 Recommended practices for installation of plastic piping systems for soil and waste discharge within
the building structure is covered by CEN/TR 13801 [12].
NOTE 3 Practices for underground installation of rainwater infiltration and storage attenuation systems are
covered by CEN/TR 17179 [13].
NOTE 4 It is assumed that additional recommendations and/or requirements are detailed in the individual
product standards.
NOTE 5 If non-plastic components are part of the plastic system there will be applicable manufacturer's
instructions.
Requirements and instructions concerning commissioning of systems can be found in EN 805 and
EN 1610 and the relevant national and/or local regulations. This document gives specific additional
recommendations for commissioning relevant for plastic piping systems.
Attention is drawn to any relevant local and/or national regulations (e.g. health, safety and hygienic
requirements).
