viemärivesi

Viemärivesi, also known as wastewater or sewage, refers to water that has been contaminated by human activities and is no longer suitable for its original purpose. This includes domestic wastewater from households, industrial wastewater from factories, and stormwater runoff from urban areas. The composition of viemärivesi can vary widely depending on its source, but it typically contains organic matter, pathogens, nutrients, chemicals, and suspended solids.

Proper management of viemärivesi is crucial for public health and environmental protection. Untreated or inadequately treated wastewater can pollute rivers, lakes, and oceans, harming aquatic ecosystems and posing health risks to humans through contaminated drinking water sources or recreational activities. Wastewater treatment plants are designed to remove pollutants from viemärivesi through various physical, biological, and chemical processes before it is discharged back into the environment.

The collection of viemärivesi is typically handled by a network of underground pipes called sewers. These sewer systems transport wastewater from its source to treatment facilities. In areas without centralized sewer systems, individual septic systems are often used for on-site treatment and disposal. Efficient and well-maintained wastewater infrastructure is essential to prevent overflows and leaks that can lead to environmental contamination and public health hazards.
