What is building drainage? What are its aims and requirements.

Building drainage is part of the drainage system at the lowest piping network which receives the discharge from waste, soil, and other drainage pipes and conveys it to the sewer from the line of building walls.

Aims of building drainage:

• Building drainage maintains the healthy condition of the building
• Wastewater can be disposed of daily condition and quickly
• Gives us the facility to remove foul matter.
• Avoid the gases coming from foul matter

Requirements for building drainage:

• Building drainage is required as it allows foul matter to drain out quickly.
• All the materials and fittings of this drainage should be strong, and resistive to corrosion.
• Rainwater pipes drain out it directly to the street gutters and from that is connected to the stormwater.
• The drainage should be constructed at a slope that should have its cleansing velocity.
• Drains should be aligned between inspection chambers.
• The drains should be of a size to handle maximum discharge.
