Construction and testing of drains and sewers
This European Standard is applicable to the construction and testing of drains and sewers normally buried in the ground and usually operating under gravity. The construction of pipelines operating under pressure is covered by this European Standard together with EN 805 as appropriate. This European Standard is applicable to drains and sewers installed in trenches, under embankments or above ground. For trenchless construction EN 12889 applies. Additionally other local regulation should be taken into account e.g. concerning health and safety pavement reinstatement and requirements for tightness testing.
This standard does not apply for planning and design in accordance with EN 752.
Einbau und Prüfung von Abwasserleitungen und -kanälen
Diese Europäische Norm gilt für den Einbau und die Prüfung von Abwasserleitungen und kanälen, die üblicherweise erdverlegt sind und unter Freispiegelbedingungen betrieben werden.
Die Bauausführung von Rohrleitungen, die unter Druck betrieben werden, wird ebenfalls in dieser Euro-päischen Norm behandelt, wobei auch EN 805, falls erforderlich (z. B. für die Prüfung), zu berücksichtigen ist.
Diese Europäische Norm ist für Abwasserleitungen und -kanäle in Gräben, bei Dammbedingungen oder oberirdischer Verlegung anwendbar. Für die grabenlose Verlegung gilt EN 12889. Ergänzend sollten weitere örtliche oder nationale Bestimmungen beachtet werden, z. B. der Arbeitsschutz, die Wiederherstellung der Straßenoberfläche und Anforderungen an die Dichtheitsprüfung.

Mise en oeuvre et essai des branchements et canalisations d'assainissement
La présente norme européenne s'applique à la mise en œuvre et aux essais des branchements et des canalisations d'assainissement habituellement enterrés dans le sol et fonctionnant habituellement en écoulement libre.
La mise en œuvre des canalisations fonctionnant en pression relève de la présente Norme européenne conjointement avec l'EN 805, le cas échéant (par exemple, en ce qui concerne les essais).
La présente Norme européenne s'applique aux branchements et aux canalisations d'assainissement posés en tranchée, sous remblai indéfini ou au-dessus du sol. La pose sans tranchée est traitée dans l'EN 12889. En outre, il convient de prendre en considération d'autres réglementations locales ou nationales, concernant par exemple la santé et la sécurité, le rétablissement des chaussées, les exigences liées aux essais d'étanchéité, etc.
NOTE De plus amples informations avec des références à des documents nationaux sont fournies dans une Annexe informative.
Gradnja in preskušanje cevovodov za odvod odpadne vode in kanalizacijo
Ta evropski standard obravnava polaganje in preskušanje vodov in kanalov za odvajanje vode, ki so navadno položeni v zemljo in običajno delujejo v pogojih težnosti (s prosto gladino). Ta evropski standard obravnava tudi gradnjo tlačnih cevovodov, pri čemer je treba po potrebi upoštevati tudi standard EN 805. Ta standard se uporablja tudi za izvedbe vodov in kanalov v jarkih in pod nasipi ali za namestitev nad terenom. Za izvedbo brez izkopa se uporablja standard EN 12889. Dodatno naj bi se upoštevali drugi lokalni predpisi, npr. v zvezi z zdravjem in varnostjo, vzpostavitvijo prvotnega stanja na površini ceste in zahtevami za preskušanje tesnosti. Ta standard se ne uporablja za načrtovanje in oblikovanje v skladu s standardom EN 752.

or when applicable between the trench supports at any level
3.8
native soil
soil from the excavation of the trench
3.9
nominal size
DN
numerical designation of size of component, which is a convenient integer approximately equal to a
manufacturing dimension in mm.

5 General
5.1 Technical principles
Pipelines and manholes are essentially engineering structures in which the combined performance of con-
struction components, embedment, backfill and native soil constitute the basis for stability and safety in
operation. The pipes, fittings and joint materials supplied, together with the work carried out at site, such as
the pipe bedding, the jointing of pipes, the sidefilling and backfilling are all important factors in achieving a
structure with adequate performance.
A procedure shall be established for the agreement of changes to design decisions made during construction.
The load bearing system shall be capable of bearing available and future loads with a sufficient level of safety.
In this context, safe operation of the drain or sewer is a criterion besides load transfer.
The definite realisation of the planning specifications is decisive for the quality of the construction works. The
network owner and the planner shall coordinate the extent and the requirements of the engineering services to
be rendered for the individual case.
The structural and dynamic loads acting upon drains and sewers shall be defined during planning. They also
include loads from construction states that may be determinant for dimensioning.
5.2 Safeguarding design decisions
The strength of a pipeline shall be determined, decided or specified before construction work is undertaken in
accordance with EN 752 and EN 1295-1.
In the execution of the work it should be ensured that the decisions made in the design are safeguarded or
adapted to changed conditions.
The design decisions are affected in particular by any variation of the following which should be checked:
trench width (see 7.3);
trench depth;
trench support system and the effect of its removal (see 7.4);
degree of compaction of the embedment;
degree of compaction of main backfill;
pipe support and trench bottom conditions;

construction traffic and temporary loads;
soil types (e. g. subsoil, trench walls, backfill);
shape of trench (e. g. stepped trench, trench with sloping walls);
ground and soil condition (e. g. frost and thaw, rain, snow, flooding);
ground water table;
additional pipelines in the same trench.
NOTE The above list is not exhaustive.
6 Construction components and materials
6.1 General
Construction components and materials shall conform to national standards transposing European Standards
as available, or to European technical approvals or in the absence of these the components and materials
shall comply with the requirements of the designer and EN 476.
6.2 Construction components
Construction components shall comply with 6.1.
Any supplementary instructions of the manufacturer shall be observed.
6.3 Materials used for embedment
6.3.1 General
The materials used for embedment shall comply with the appropriate subclauses of 6.3 in order to be capable
of providing permanent stability and load bearing capacity for the pipeline buried in the ground. Such materials
shall not be detrimental to the pipe or pipe materials or the groundwater.
Frozen materials shall not be used unless specific requirements are in place defining the conditions of use.
Materials used for embedment shall conform to the design requirements. The materials may either be native
soil (see 6.3.2) if proved to be suitable or imported materials (see 6.3.3). Materials for bedding should contain
no particles with sizes above
15 mm for DN < 100;
22 mm for DN ≥ 100 up to DN ≤ 200;
40 mm for DN > 200 up to DN ≤ 600;
60 mm for DN > 600.
6.3.2 Native soil
Requirements for re-use of native soil shall include:
conformity with design requirements;

compactability if specified;
freedom from materials detrimental to the pipe (e. g. "oversized" particles – depending on pipe material,
wall thickness and diameter –tree roots, waste, organic material, snow and ice (frozen together));
specific requirements applicable to native soil including clay lumps which shall not exceed 75 mm.
Special consideration shall be taken by the designer when specifying particle sizes exceeding 40 mm.
Native soil meeting the requirements of 6.3.3.2 or 6.3.3.4 is considered suitable.
