There are three main types of sewer systems:
- An economic and household system that can be centralized (for entire locality) and autonomous (one or more objects)
- Stormwater drainage used to drain wastewater formed as a result of precipitation
- Industrial sewage system designed for the collection and treatment of wastewater in production
All three types of sewerage systems are divided into internal and external
Internal System - devices and pipelines of household plumbing mounted inside the facility
External System - pipes, pumping stations, and sewage treatment plants located behind the walls of a building
Sewage systems are one of the most important components of technological installations, without proper and reliable operation, any operation is impossible. The operation of sewerage systems is determined by technical regulations.
