From the Document: "There is an inextricable link between COVID-19 [coronavirus disease 2019] , wastewater, and sanitation. The COVID-19 pandemic has highlighted the threats and opportunities regarding sanitation and wastewater management. [...] COVID-19 also highlights the need to invest in wastewater treatment facilities and adequate sanitation. In many areas of the world, huge quantities of wastewater are released in the environment without treatment or adequate treatment, deteriorating our environment, and posing serious risks to human health. Raw sewage, and partially-treated wastewater, are vehicles for spreading diseases, and in this case, a potential mechanism for COVID-19 to spread faster, for example in areas where sanitation is poor, or where the communities are exposed to open-sewers and black water."
