TP177 - Uredba o odvajanju in čiščenju komunalne odpadne vode

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. 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.

This European Standard specifies requirements, test methods, evaluation of conformity and marking for prefabricated secondary treatment units used for the treatment of effluent from septic tanks according to EN 12566-1 or EN 12566-4 in small wastewater treatment systems for up to 50 PT.

This European Standard specifies the requirements for septic tanks assembled in situ from prefabricated kits and ancillary equipment where applicable, used outside buildings for the partial treatment of domestic wastewater for a population up to 50 PT. Pipe sizes, loads, watertightness, marking and evaluation of conformity are specified. This standard does not apply to septic tanks receiving grey water only.

This European Standard specifies the requirements for prefabricated septic tanks and ancillary equipment used for the partial treatment of domestic wastewater for a population up to 50 PT. Pipe sizes, loads, watertightness, marking and quality control are specified. The following cases are excluded: - septic tanks receiving grey water only; - in situ constructed septic tanks.

This standard specifies requirements for filtration systems ranging from single house up to and included 50 PT receiving domestic wastewater from septic tanks manufactured according to the requirements given in EN 12566-1 and EN 12566-4.
This document is considered as a code of practice and gives design parameters, construction details, installation and component requirements for constructed sand filters and subsurface flow reed beds.
Designs of filtration systems not covered by this standard may be tested and assessed to prEN 12566-3, Annex B.

This document specifies the recommended requirements for soil infiltration systems ranging in size from a single house to 50 PT receiving domestic wastewater from septic tanks manufactured according to the requirements given in EN 12566-1 and prEN 12566-4.
This document gives design parameters, construction details, installation and component requirements for soil infiltration systems.
