The house drainage system is basically a critical component of the house plumbing system. An efficient drainage system is essential for the healthy lifestyle of the residents.
The house drainage system consists of a network of drainage pipes, manholes, inspection chambers, and other sewer fixtures designed to carry the wastewater generated by domestic activities safely.
The house drainage system is designed with three types of drainage pipes. The first type of drainage pipe is called soil pipe or sewage pipe. The second type of drainage pipe is called a sullage pipe and the third one is ventilation or simply a vent pipe.
The residential apartments essentially produce two types of wastewater. The first type of wastewater produced in the kitchen contains no harmful bacteria.
However, the second type of wastewater ( sewage ) produced in the bathroom and washroom contains human waste that contains some harmful elements.
The house drainage system is designed to handle both the waste and safely discharged it into the municipal drain located outside the building premises. The drainage pipe ventilation is another important aspect of the design.
