1 Scope
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), Glass Reinforced Polyester (GRP-UP), Polydicyclopentadiene (PDCPD) and container made of flexible sheets (PEHD, PP, PVC,
EPDM).
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.
