Bibliography

Describes lifting plants for wastewater containing faecal lifting plants which may also be used to deal with wastewater that does not contain faecal matter, for drainage of locations in buildings and sites below flood level for buildings and sites to prevent any backflow of wastewater into the building. Also specifies general requirements, basic construction and testing principles, together with information on materials and conformity evaluation.
