- Near horizontal pipe suspended within a building or buried in the ground to which stacks or ground floor appliances are connected.
Note: In accordance to BS EN 12056-3:2000, the near horizontal drainage pipes are to be designed based on open channel principle. As such for pipes at a gradient of less than 10° from horizontal are designed as drains with maximum 70% fill rate. The flow in offsets less than 10° to the horizontal shall be calculated as a drain with a filling degree of not more than 70% unless national and local regulation and practice states otherwise.[1]
- Includes any canal, culvert, conduit, river or watercourse. [2]
- Pipeline, usually underground, designed to carry wastewater from a source to a sewer. [3]
