It is called the sewer network to the system of structures and pipes used to transport wastewater or rain, from the place where they are generated to the place where they are discharged into the riverbed or treated.
The Sonsón's sewerage networks are a combined system, that is, they bring together sewage and rainwater, technically called unitary systems. Due to the steepness of the city, the sewer pressure is driven by gravity and has a coverage of around 90% with continuous expansion by our engineers and operators
The components of a sewer network are:
Tertiary C olectors: These are small diameter pipes (150 to 250 mm internal diameter), which are placed in the basement, to which the household connections are connected.
Secondary collectors: These are the pipes that collect the water from the tertiary and lead them to the main collectors. They are located buried, on public roads.
Main collectors: These are large diameter pipes, generally located in the lower parts of cities, and transport the wastewater to its final destination.
Inspection wells: They are vertical chambers that allow access to the collectors, to facilitate their maintenance.
Processing facilities Wastewater Treatment Plant (WWTP): There are several types of treatment stations, which, due to the quality of the water leaving it, are classified into: primary, secondary or tertiary treatment stations.
Final discharge of the treated water: the final discharge of the treated water is l led to a river.
