Various Waste Water Pipes (Sewer Construction)

Waste water pipes maintain proper hygienic conditions in any building. They are used for proper outlet of waste water from the house. The pipes prevent home from foul smell of waste water also. There are various types of pipes available in the market to ensure sanitary conditions in any structure. Here we have enlisted the types of pipes for proper drainage of waste water. 

Clayware Pipes 

Clayware waste water pipes are convenient in handling and layout. They have rigid fittings and do not distort under loading. They maintain good corrosion resistance.
The pipes provide flexible joints at sufficient and frequent intervals.

Fiber Cement Pipes

These type of waste water pipes are resistant to corrosion and maintain qualities of both concrete and inorganic fiber.  They have a service life of minimum 50 to 75 years and do not create any problems in storage. They remain unaffected in strength by high temperatures and maintain thermal conductivity approximately 120 times less than metal pipes. They have smooth bores and low friction losses.

Fiber cement pipes maintain their carrying capacity during service period. These waste pipes improve with the passage of time and yield to better test results in terms of strength when kept in humid environment. The ends of pipes can be turned into accurate dimensions. The pipes can be drilled, cut, turned at the site of job by handy tools. 

Concrete Pipes 

These pipes are environment-friendly and provide structural strength. These are generally used for carrying the waste water from the sewer line.They are resistant to abrasion and most chemicals. They are easy to install and have a history of reliability. The pipes get stronger with the passage of time and life cycle of a steel reinforced concrete pipe is considerably longer than other drainage pipes.   
 
Ductile Iron Pipes   

These pipes are chemical resistant and have high tensile strength. These waste water pipes are best suitable for carrying the industrial waste.These are also resistant to second cover damage.  They are economical and easy in installation. They are not damaged while handling or during transportation. They have high elongation (ductility).

Recommended size of waste water pipes 

The diameter of waste water pipes should be based on fixture units.  Branches and piles receiving discharges from soil appliances should not be less than 100 mm diameter. Outlet of floor traps may be of 75 mm diameter. Waste stack should have a minimum diameter of 75 mm.  

Various colors indicating Sewer, Waste and Water Pipes

•  Red color indicates sewers. 
•  Blue color indicates waste water pipes. 
•  Blue color marks rain water pipes also.
•  Black color marks existing works.
