Wastewater can be a valuable resource for public and environmental Health. Wastewater from our homes, toilets, and public infrastructure carries traces of pathogens, chemicals, and pollutants. It reflects the health of communities and is increasingly recognised as a critical tool for monitoring disease outbreaks, pollution levels, and risks to both ecosystems and human well-being.
During the COVID-19 pandemic, wastewater monitoring emerged as an effective method for early detection of viral outbreaks. It provided a fast, cost-effective, anonymous, and non-invasive alternative to clinical testing. By 2022, wastewater-based surveillance systems had been implemented in at least 55 countries.
But its value goes far beyond pandemics.
Wastewater surveillance helps identify land-based sources of pollution, informs ecosystem protection strategies, and supports the development of evidence-based policies to safeguard freshwater and marine environments. It plays a dual role in protecting public health and supporting the sustainable management of natural resources.
