EN 12050-1:2015 (E) 5 1 Scope This European Standard applies to lifting plants for wastewater containing faecal matter (referred to as “faecal lifting plants” in this standard) for drainage of locations below flood level in buildings and sites to prevent any backflow of wastewater into the building. These lifting plants may be prefabricated or delivered as prefabricated kits and assembled on site. This standard specifies general requirements, basic construction and testing principles, together with information on materials and assessment and verification of constancy of performance. Construction and testing requirements for non-return valves used in wastewater lifting plants are given in EN 12050-4. This European Standard does not apply for pumping installations for drain and sewer systems outside buildings for pumping of municipal wastewater according to EN 752:2008, Annex F. NOTE
Lifting plants for wastewater containing faecal matter can also be used for wastewater that does not contain faecal matter and for surface water. This European Standard applies also to lifting plants for wastewater containing faecal matter which are not prefabricated but composed of individual components purchased from different suppliers and put together on site. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

Examples of suitable materials for the construction of wastewater lifting plants are given in Annex A (informative). For collection tanks only corrosion resistant materials or materials with a corrosion resistant protective coating shall be used. 4.2 Collection tank 4.2.1 Mechanical resistance The structural stability of collection tanks shall be shown to be adequate for the place of installation. When tested according to 5.2.1 the tank shall be tight and shall not show any deformation influencing subsequent function of the lifting plant. Where loads on the tank may be expected the load bearing capacity of the collection tank shall be shown to be adequate for the place of installation and the crushing resistance or maximum load deformation (as applicable) shall be tested and declared in accordance with appropriate standards, e.g. EN 13598-1:2010 or EN 12566-1:2000/A1:2003, Annex D.

Collection tanks for use at sites outside buildings shall be covered and watertight. If not tested according to 5.2.1 because the collection tank is assembled on site, the watertightness shall be tested and declared according to EN 12566-4. 4.2.3 Odourtightness Collection tanks for use inside buildings, other than inlet, outlet and vent openings, shall be closed and odourtight when tested according to 5.2. 4.2.4 Protection against explosion The inside of the collection tank of a faecal lifting plant can be regarded as a zone containing potentially explosive gases. NOTE In those cases, the collection tank is regarded as zone 2 in accordance with Directive 1999/92/EC (ATEX operative guideline) and considered as temperature class 3. Where protection against explosion is required, the collection tank and any device inside the tank shall meet the requirements of EN 13463-1 and EN 60079-0 and be tested accordingly and the product shall be marked as such. 4.3 Lifting effectiveness 4.3.1 General Faecal lifting plants shall be capable of pumping wastewater as defined in EN 12056-1 including all the solid matter usually contained in domestic wastewater. They shall be designed in such a way that solid matter does not accumulate in any of their included components. NOTE For pumping sewage with abrasive particles present (e.g. sand), faecal lifting plants fitted with faecal macerating mechanisms are of their nature not suitable. When tested in accordance with 5.3 the plant shall not show malfunction which could affect the operation of the plant. 4.3.2 Pipe connections The dimensions of inlet, discharge and ventilating connections shall permit the use of standard pipe sizes. Connections shall be such that a flexible and sealed connection is ensured. The discharge pipe connection shall withstand a pressure that is 1,5 times the maximum pump operating pressure without leaking. In case a positive displacement (PD) pump is used the pressure can rise to unexpectedly high values due to blockages in the discharge pipe for which case adequate safety measures shall be taken. 4.3.3 Minimum dimensions of ventilating pipe system In the case of flows up to 12 l/s the ventilating pipe shall have a minimum size of DN 50. In the case of higher flows the ventilating pipe shall be a minimum of DN 70. SIST EN 12050-1:2015

The ball passage of the non-return valve shall be at least 60 mm. Where permitted, the discharge connection shall be at least DN 50 and the ball passage of the non-return valve shall also be at least 50 mm. SIST EN 12050-1:2015

In the case of macerating faecal lifting plants and discharge pipes DN ≤ 50 the useful volume can be reduced to 10 l. According to EN 12056-4 the minimum useful volume shall be higher than the volume of the discharge pipe. 4.4 Control equipment Faecal lifting plants shall be fitted with control equipment for automatic operation of the plant and with a warning device.
