Calculation of sewage
Internal sewage is designed to remove household waste. Sewage in a separate house usually consists of a gravity system, where movement occurs under the influence of gravity. The advantage of such a system is that no additional energy consumption is required.
So what does a classic internal sewage system consist of?To prevent odors from sewage pipes from entering residential premises, practically every plumbing fixture is equipped with a trap.On the other hand, for sewerage systems, free access to air is achieved by arranging fan or ventilation risers.Practically every internal sewage system of a house consists of the following list of parts:
- stations for pumping or cleaning waste;
- tanks for receiving waste;
- collectors;
- pipelines;
- risers;
- discharge lines.
Installation of internal sewage
Installing sewage pipes is a long and laborious process that requires following a certain sequence of actions, thoroughness, and accuracy. The well-being of the system's installation and design will determine its operational properties, as well as the reliability and durability of its operation. If you are creating the project yourself, it is necessary to show it to a specialist to identify possible deviations from the norm. If the project is approved, then you can proceed to purchase the materials needed for installation.Installation of sewage risers.
Installation of any sewage starts with risers. First, marking is done according to the plan, and then they proceed to the installation of pipes.When installing a riser, it is necessary to place it strictly vertically, as well as prevent distortions and fractures at the pipe joints.When laying the pipeline, the pipes are installed upwards with sockets starting from the basement and simultaneously installing inspection chambers. Traditionally, inspection chambers are installed at all pipe turn locations, at each fixture riser, and at the end of the internal sewage system. At the end of each sewage riser, ventilation is mandatory, which is vented to the roof or attic in the form of a personal ventilation channel.Immediately with the riser on each floor, installation of discharge horizontal lines is carried out.After installing the risers, discharge lines from all sanitary devices are connected to them. Their diameter should be the same as the diameter of the outlet of each of these devices.The calculation of sewage for a house involves a maximum pipe length of 10 meters, and the angle of their inclination should be such that there are no obstacles to the free flow of wastewater to the riser.
