What is BS EN 12050-3 - Lifting plants for domestic non-commercial wastewater about?
BS EN 12050 is a European Standard that discusses wastewater lifting plants for buildings and sites. The aim of the BS EN 12050 series is to provide best industry practices for the optimal functioning of lifting stations, such that wastewater can be pumped from a lower to higher elevation and sewage collection and disposal is carried out effectively.
BS EN 12050-3 is the third part of the series that applies to lifting plants for limited application for domestic non-commercial wastewater containing or not containing faecal matter and below flood level in buildings and sites to prevent any backflow of wastewater into the building.
BS EN 12050-3 applies to lifting plants for limited applications designed for wastewater containing faecal matter, where there is another WC available above flood level, and the plants serve no more than a single WC to which it is directly connected (at a distance of max. 0,5 m) and one hand washbasin, one shower and one bidet provided no other sanitary appliance is directly or indirectly connected.
BS EN 12050-3 also applies to lifting plants for limited applications designed for faecal free wastewater, where a maximum of one hand washbasin or kitchen sink plus one further appliance such as a bathtub or a washing machine or a shower or a dish washer or a urinal are connected.
Note: BS EN 12050-3 does not apply for lifting plants for limited applications for wastewater containing faecal matter where WC flushing is carried out by pressure flush valve.
Who is BS EN 12050-3 - Lifting plants for domestic non-commercial wastewater for?
BS EN 12050-3 on lifting plants for limited application is relevant to:
- Companies involved with professional drainage, cleaning and the controlled discharge or reuse of water
- Manufacturers, designer and installers of lifting plants
- Quality testing teams
- Wastewater treatment plants
- Building project planners and management authorities
- Local authorities
Why should you use BS EN 12050-3 - Lifting plants for domestic non-commercial wastewater?
Wastewater leaving homes, buildings and sites generally flow by natural gravity. However, bathrooms and toilets that are located below flood level, need lifting stations to pump wastewater from a lower to higher elevation, to ensure wastewater can flow into sewers, for safe and hygienic disposal. Moreover, these lifting plants also play an integral role in moving sewage to a wastewater treatment plant. Hence, it is necessary that these lifting plants offer adequate performance.
In this regard, BS EN 12050-3 specifies the general requirements, basic construction and testing principles, together with information on materials and assessment and verification of constancy of performance, for faecal lifting plants.
Complying with materials and product characteristics that meet BS EN 12050-3 requirements can ensure that the lifting plants are safe and reliable to use.
With BS EN 12050-3 you can also test for hydraulic performance, tightness, and lifting effectiveness, and verify whether your products are fit for purpose.
As a result, BS EN 12050-3 ensures your lifting plants play a positive role in the performance of sewage collection and disposal systems.
