The improper management of wastewater can have severe environmental and health consequences.

The primary problem arises from the fact that many Southern European countries have aging infrastructure and a lack of investment in modernizing their sewage treatment facilities. As a result, large volumes of untreated or partially treated sewage are discharged directly into nearby water bodies. This practice introduces a range of pollutants, including organic matter, nutrients, and pathogens, which can have detrimental effects on aquatic ecosystems.

Organic matter, such as food waste and human waste, decomposes in water and depletes oxygen, leading to a process known as eutrophication. This phenomenon causes algal blooms, which can be toxic and harmful to fish and other aquatic life. Nutrients like nitrogen and phosphorus, often present in high concentrations in sewage, also contribute to eutrophication and can lead to the creation of dead zones in rivers and coastal waters, where no life can survive.

Pathogens, including bacteria and viruses, pose a significant risk to human health. Untreated sewage can introduce these harmful microorganisms into water sources, leading to the contamination of drinking water and the spread of waterborne diseases. This is especially critical in regions where healthcare infrastructure may be limited, and access to clean water is essential for public health.

To address this issue, governments and local authorities in Southern Europe should prioritize the development and implementation of sustainable sewage treatment solutions.
