ühiskanalisatsioon

Ühiskanalisatsioon refers to a centralized system for collecting and transporting wastewater and stormwater from a community. This system typically comprises a network of underground pipes, known as sewers, which direct the collected water to a treatment facility. The purpose of a ühiskanalisatsioon is to protect public health and the environment by removing sewage and other pollutants from populated areas.

The design and operation of a ühiskanalisatsioon can vary. Some systems are combined, meaning they carry both sanitary sewage from homes and businesses as well as surface runoff from rain and snowmelt in the same pipes. In contrast, separate sewer systems utilize distinct pipelines for sanitary waste and stormwater. Combined systems can lead to overflows during heavy rainfall, where untreated sewage is discharged into waterways. Separate systems help mitigate this issue but may require more extensive infrastructure.

Wastewater collected by the ühiskanalisatsioon is transported to a wastewater treatment plant. Here, various physical, chemical, and biological processes are employed to remove contaminants before the treated water is discharged back into the environment, often into rivers or lakes. The solids removed during treatment are typically processed into biosolids, which may be used as fertilizer or disposed of. Maintenance of the ühiskanalisatsioon, including regular cleaning and repair of pipes, is crucial to ensure its efficient and effective operation and to prevent blockages and system failures.
