Small wastewater treatment systems for up to 50 PT - Part 3: Packaged and/or site assembled domestic wastewater treatment plants
This European Standard specifies requirements, test methods, the marking and evaluation of conformity for packaged and/or site assembled domestic wastewater treatment plants (including guest houses and businesses) used for populations up to 50 inhabitants. Small wastewater treatment plants according to this European Standard are used for the treatment of raw domestic wastewater.
It covers plants with tanks made of concrete, steel, PVC-U, Polyethylene (PE), Polypropylene (PP) and Glass Reinforced Polyester (GRP-UP).
The test methods specified in this European Standard establish the performance of the plant, needed to verify its suitability for the end use (see 3.1).
This European Standard applies for small wastewater treatment plants for use buried in the ground where no vehicle loads are applied to the product.
This European Standard applies to plants where all prefabricated components are factory or site-assembled by one manufacturer and which are tested as a whole.
NOTE In some countries, domestic wastewater treatment plants are followed by other systems to conform to national regulations.

Petites installations de traitement des eaux usées jusqu'à 50 PTE - Partie 3: Stations d'épuration des eaux usées domestiques prêtes à l'emploi et/ou assemblées sur site
La présente Norme européenne spécifie les exigences, les méthodes d’essais, le marquage et l’évaluation de la
conformité de stations d’épuration d’eaux usées domestiques prêtes à l’emploi et/ou assemblées sur site, utilisées
pour une population totale équivalente (PTE) jusqu’à 50 habitants (y compris pour des établissements hôteliers et
entreprises). Les petites stations d’épuration dont il est question dans la présente Norme européenne sont utilisées
pour le traitement des eaux usées domestiques brutes.
Elle traite des stations avec réservoirs en béton, acier, PVC-U, polyéthylène (PE) et plastique renforcé de
verre (PRV).
Les méthodes d’essais spécifiées dans la présente Norme européenne établissent les performances de la station,
qui sont requises pour vérifier l’aptitude de la station à l’emploi (voir 3.1).
La présente Norme européenne est applicable aux petites stations d’épuration des eaux usées enterrées à un
emplacement où le produit n’est pas soumis à des charges dues aux véhicules.
La présente Norme européenne est applicable à des stations dont tous les composants sont préfabriqués en usine
ou assemblés sur site par un même fabricant et qui sont soumises aux essais comme un tout.
NOTE Dans certains pays, pour la conformité aux réglementations nationales, les stations d’épuration des eaux usées sont
complétées par d’autres systèmes.
