Private drainage system

Private drainage system is the set of pipes and parts in charge of collecting all the water that evacuates the different sanitary and domestic appliances and taking them to a maura pit , a septic chamber , or to the sewer .

Elements that form a drainage system

  • Pipes
  • Sifas
  • Y-shaped and T- shaped tubes
  • Ventilation system.

Ventilation system

It is the set of pipes and pieces of sanitary cast iron that aims to collect all the gases coming from the drainage systems and take them to a point higher than the roof or roof of the building.

Characteristics of a ventilation system:

  • 1% fan slope
  • Maximum length of the 5 m fan horse’s back
  • Horse height from the finished floor level of 0.80 m to 1 m.
  • Length of the arms or candlesticks from the discharge center to the nearest wall must be 0.62 m.

General fans

They are tubes that are placed vertically and go from the first floor, linking the intermediate, to the last. This tube extends to the highest part of the building. With the placement of the general fan on the head of the discharge pipeline, a much faster discharge is possible and obstructions in the drainage systems are prevented by the formation of air columns.

Classification of drainage systems

The drainage systems can be classified into two types:

  • Static evacuationsystem: Static evacuation system is considered when the drainage system pours its waters into a maura pit , a septic tank , and so on.
  • Dynamic evacuationsystem: Dynamic evacuation system is considered when the drainage system discharges to a sewage system , purification plant , etc.

Difference between a drainage system upstairs and downstairs:

The fundamental difference between a drainage system on the upper floor and one on the ground floor is that the materials used to build them, as well as the slope used, are different. On the upper floor they are used to build drainage systems, pipes and sanitary cast iron parts and their slope is 1½% per meter in length, while on the ground floor pipes and pieces of vitrified or glazed mud are used and the slope is 2% per meter in length. It is good to keep in mind that pipes and plastic parts can be used interchangeably on the upper floor or on the ground floor.

Importance of drainage systems

The importance of drainage systems, regardless of the system used, is that in order to be possible to live in a construction site, it is necessary that they have such systems, since they evacuate solid and liquid waste from different sanitary and domestic appliances .
