CE tests according to EN 12566
The basis for a successful market entry in Europe is the CE marking of your product. For this purpose, the series of standards – EN 12566 – is used. Five of the seven standards have been harmonised and, with our support, you can receive a declaration of performance according to one of these standards and place it on your product. With it, small wastewater treatment plants can be traded legally throughout Europe.
The standard EN 12566 is divided into several parts, each of which defines the basis for the respective tests:
Part 1: Prefabricated septic tanks
Additional tests for septic tanks according to EN 12566-1

Defining the nominal capacity
Along with the water tightness test, the usable volume of a septic tank must be measured and defined. To do this, the volume of water is measured at the height of the outlet with a calibrated measuring device (magnetic induction).
Test of the hydraulic efficiency
The hydraulic efficiency is used to measure of the retention of the settleable solids and floating material from septic tanks. To do this, polystyrene beads are utilised to simulate the settleable solids and floating matter. The result is expressed by the amount of polystyrene beads collected in the effluent of the septic tank in grams.
Part 3: Packaged and/or site assembled domestic wastewater treatment plants
The important standard EN12566-3 is used to test constructed wetlands and small wastewater treatment plants with biological purification for the European market. As with septic tanks, the plants are checked for stability, water resistance and durability. In some cases, the plant’s reaction to fire and the possible release of dangerous substances is also tested.
The significant test of the treatment efficiency is carried out in PIA’s test field over a period of 38 weeks. Once delivered, your treatment plant is placed in the test field by the PIA team and charged with domestic wastewater. After the necessary start-up phase, in which the biological process begins running, the actual testing of cleaning performance begins. Emerging requirements for desilting should be considered when new tests are conducted. Secure key advantages of your plant and talk to our experts.
Part 6: Prefabricated treatment units for septic tank effluent
In addition to testing the septic tanks as a first treatment stage in accordance with EN 12566-1, you can also individually CE-mark the second treatment stage so that you can place them on the market. Plants of the second treatment stage (usually bioreactors), which generally treat wastewater coming from septic tanks, are tested according to the relatively new standard EN 12566-6. Here too, the 38-week test with different test modes is used to verify the treatment efficiency. The tests of the tank, however, are carried out according to the standard EN 12566-3. We can show you various combinations so that you can reduce costs. Talk to us.
Part 7: Prefabricated tertiary treatment units
The youngest and most underestimated small wastewater standard is EN12566-7. By means of this harmonised standard, tertiary treatment stages can be tested for CE compliance. These tertiary stages treat wastewater leaving small wastewater treatment plants according to Part 3 or Part 6 of the standard series. Here, four different processes are distinguished from one another: physical and biological processes are subjected to a 16-week test and chemical or electrical processes to a 7-week test. Ask us for details or a quotation so that your plant can be CE-marked and sold all over Europe.
