vesihuoltoketjun

Vesihuoltoketju refers to the entire process of supplying safe and clean water to consumers and treating wastewater. It begins with the abstraction of raw water from natural sources such as rivers, lakes, or groundwater. This raw water is then transported to a water treatment plant.

At the water treatment plant, a series of physical and chemical processes are employed to remove impurities and contaminants. These steps typically include screening to remove large debris, sedimentation to allow heavier particles to settle, filtration to remove smaller suspended solids, and disinfection to kill harmful microorganisms like bacteria and viruses. Disinfection is crucial for ensuring the water is safe for consumption.

Once treated, the clean water is stored in reservoirs or tanks before being distributed to households and businesses through a network of pipes. This distribution system is a complex infrastructure that requires ongoing maintenance to prevent leaks and ensure consistent water pressure.

The final stage of the vesihuoltoketju involves the collection and treatment of wastewater. Used water from homes and industries flows through a separate network of sewer pipes to a wastewater treatment plant. Here, wastewater undergoes processes to remove pollutants and solids before the treated effluent is discharged back into the environment, often into rivers or lakes, in an environmentally safe manner. Sludge generated during the treatment process is also managed and treated. The efficient and effective management of the entire vesihuoltoketju is essential for public health and environmental protection.
