EN 12566-3 is a candidate “harmonized” European Standard and fully takes into account the requirements of the European Commission mandate M/118 “Wastewater engineering products” as amended by M/139, given under the EU Construction Products Directive (89/106/EEC) and is intended to lead to CE marking. The date of applicability of EN 12566-3 as a harmonized European Standard, i.e. the date after which this standard may be used for CE marking purposes, is subject to an announcement in the Official Journal of the European Communities. The Commission in consultation with Member States have agreed a transition period for the co-existence of harmonized European Standards and their corresponding national standard(s). It is intended that this period will comprise a period, usually nine months after the date of availability of the European Standard, during which any required changes to national regulations are to be made, followed by a further twelve-month period for the implementation of CE marking. At the end of this co-existence period, the national standard(s) will be withdrawn. EN 12566-3 is the subject of transitional arrangements agreed under the Commission mandate. In the UK there are no corresponding national standards. The UK participation in its preparation was entrusted to Technical Committee B/505, Wastewater engineering, which has the responsibility to: A list of organizations represented on this committee can be obtained on request to its secretary. aid enquirers to understand the text; present to the responsible international/European committee any enquiries on the interpretation, or proposals for change, and keep UK interests informed; monitor related international and European developments and promulgate them in the UK.

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2006, and conflicting national standards shall be withdrawn at the latest by July 2008. This European Standard has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). For relationship with EU Directive(s), see informative Annex ZA, which is an integral part of this European Standard. This European Standard provides the general requirements for packaged and/or site assembled treatment plants used for domestic wastewater treatment up to 50 PT (see Clause 1 “Scope“). The standard EN 12566 “Small wastewater treatment systems up to 50 PT“ contains the following Parts: Part 1: Prefabricated septic tanks; NOTE 1 This part specifies the requirements and test methods for prefabricated septic tank units. Part 2: Soil infiltration systems NOTE 2 This CEN/TS is a Code of Practice for in-situ constructed soil infiltration systems. No treatment requirements are specified. Part 3: Packaged and/or site assembled domestic wastewater treatment plants; NOTE 3 This part specifies the requirements and test methods used to evaluate packaged wastewater treatment plants which are required to treat sewage to a predetermined standard. The following Parts are in preparation: Part 4: Septic tanks built in situ from prefabricated kits Execution standard; Part 5: Pre-treated Effluent Filtration systems. Figure 1 shows the relationship between the parts of EN 12566. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.

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. 2 Normative references The following referenced documents are indispensable for the application of this European Standard.
