European Standard EN 12566:3

On 20 June 2005, the European Committee for Standardisation (CEN) approved European Standard EN 12566:3 “Small wastewater treatment units for up to 50 people – Part 3: domestic wastewater treatment plants pre-fabricated and/or assembled on site”. Between 31 July 2006 and 22 April 2007, WCST WWTPs were tested at the Prüfinstitut für Abwassertechnik GmbH [Institute of Wastewater Technology Testing Ltd] in Aachen, Germany, in compliance with standard EN 12566-3:2006. In May 2007, the company received documentation containing the results of the tests confirming that the wastewater treatment was highly effective, and authorising the bearing of the CE mark on the product, as on all the company’s goods.

  • Installing a Wastewater Treatment Plant was undoubtedly a good decision. In addition to significant savings, I can use distilled water for irrigation throughout the property.
