Drainage pipelines are used to carry wastewater, sewage, and stormwater. The
best material for drainage pipes must be:
·
Corrosion-resistant
·
Chemically inert
·
Long-lasting
Ceramic pipes (also known as
clay pipes) have been traditionally used for
drainage and sewage systems due to their:
·
High corrosion resistance
·
Resistance to chemical attack from sewage waste
·
Durability and longevity
·
Smooth inner surface, reducing blockages
