What is BS EN 12050-4 - Wastewater lifting plants for buildings and sites about?
BS EN 12050 discusses wastewater lifting plants for buildings and sites. BS EN 12050-4 is the fourth part of BS EN 12050 and discusses non-return valves for faecal-free wastewater and wastewater containing faecal matter.
Non-return valve part of a wastewater lifting plant that prevents backflow of wastewater from the discharge pipe system which is either integrated with or a separate part of the plant. BS EN 12050-4 applies to non-return valves used for faecal-free wastewater and wastewater containing faecal matter lifting plants.
Who is BS EN 12050-4 - Wastewater lifting plants for buildings and sites for?
BS EN 12050-4 on wastewater lifting plants for buildings and sites is useful for:
- Wastewater plants manufacturers
- Water treatment plant owners
- Builders
- Architects
- Quality control personnel
Why should you use BS EN 12050-4 - Wastewater lifting plants for buildings and sites?
Anyone who operates a toilet, shower or washing machine in the basement is faced with a problem: These rooms are generally located below the flood level (road level). The greywater and black water produced can therefore not be drained away with a gradient. Instead, it has to be pumped by a wastewater lifting plant, so that it can flow into the sewer.
BS EN 12050-4 provides you with the general requirements, basic construction and testing principles together with information on materials and the relevant assessment and verification of constancy of performance non-return valves used for faecal-free wastewater and wastewater containing faecal matter lifting plants. BS EN 12050-4 helps you manufacture high-quality wastewater lifting plants.
