When choosing sewage materials, the following elements should be carefully taken into account.

  1. Price: The price should be fair and reasonable.
  2. Sturdiness: The substance should be sturdy.
  3. Imperviousness: The sewer’s construction material must possess this property.
  4. Abrasion Resistance: The material must be sufficiently resistant to abrasion brought on by grit moving at a high speed.
  5. Corrosion resistance: Due to the sewage’s corrosive properties, the material should be able to offer corrosion resistance.
  6. Weight: To facilitate handling and transportation, the material should be moderate in weight.
Cast iron sewer


The sewers made of cement concrete might be conventional or reinforced. Up to a diameter of 600 mm, ordinary cement concrete sewers are utilised; for diameters more than 600 mm, reinforcing is given.


  1. These are robust and resistant.
  2. A larger diameter is possible.
  3. The sewer’s interior surface is smooth.
  4. The interior surface of the structure should be lined with vitrified clay to protect it from chemical and erosive attacks.


  1. It is challenging to transport and handle heavy objects.
  2. Carefully filled joints should be used
Cement sewer


Asbestos fibres and cement are combined to create these sewers. They come in sizes up to 900mm.


  1. Easy to cut and join.
  2. Durable and good resistance to corrosion.
  3. The inside surface is smooth.
  4. Light in weight and hence easy to handle


  1. Brittle and cannot stand impact forces during handling operations.
  2. The structural strength is poor and hence cannot be laid to resist heavy external loads
