“…Thus, there is now a collective and significant interest in sewer network water quality and the information that can be obtained from wastewaters (Scassa et al 2022). This interest is only expected to grow (Manuel et al 2022).…”

There has been a recent increase of interest in sewer network water quality, both for pollutants and wastewater epidemiology. Of particular interest is the ability to perform cost-effective small-scale monitoring to understand the sewer network and perform source localization (the process of identifying the sources of materials of interest within the network), enabling prioritization of combined sewer overflow (CSO) interventions and targeted response to the detection of infectious diseases. Rhodamine WT fluorescent dye tracing was carried out in the combined sewer networks of four UK cities, for which network geometries were available. Over 100 dye concentration profiles were recorded, from which discharge, travel time (velocity), and dispersion were quantified. A simplified hydraulic and water quality (conservative solute transport) modeling approach was used to investigate dispersion further. A theoretical method for calculating dispersion over a reach with nonuniform properties was derived and used with the models and recorded data to develop a method for estimating the dispersion coefficient in sewers. Novel simultaneous injections into multiple manholes within one sewer network were conducted. Modeling of these injections validated the modeling approach and explained the measured concentration profiles, demonstrating both the potential of hydraulic and solute transport modeling and the new dispersion coefficient predictor for source localization. Such modeling can be used to develop sewer network "fingerprints" and source location probability plots based on residence time distribution (RTD) theory to maximize information from limited water quality monitoring. This will aid managers and operators in identifying potential intermittent sources of material within the network.

“…Common methodologies also need to be created across science laboratories for testing methods and performance characteristics (Kirby et al, 2021; Pecson et al, 2021). Three spheres of activity are therefore needed in wastewater surveillance across developed and developing nations: (1) the development of measurement and reporting best practices including decision‐support systems; (2) collaboration and coordination in sampling and interpretation of results; and (3) sustainable institutional infrastructure for wastewater testing programs (Keshaviah et al, 2021; Korfmacher & Harris‐Lovett, 2022; Manuel et al, 2021).…”

Wastewater-based surveillance can be used as an early warning system to identify COVID-19 outbreaks because the viral load can be observed in sewage before it is clinically verified. Wastewater surveillance of SARS-CoV-2 can trace the transmission dynamics of infection in communities when using the scale of a wastewater diversion and treatment system. Using this early detection method can help protect human health and mitigate socio-economic losses. It can help quantify the epidemiological data of a given population in real-time and circumvent the need for other epidemiological indicators. There are challenges in using this technique in areas with underdeveloped sewerage infrastructure. It is especially the case in developing nations where uniform protocols for viral detection are lacking, and wastewater is heterogeneous because of environmental and operational conditions. This article explains the need for and importance of wastewater-based surveillance for SARS-CoV-2. It lays out the most recent methodological approaches for detecting SARS-CoV-2 in municipal wastewater and outlines the main challenges associated with wastewater-based epidemiology (WBE). The article includes a case study of surveillance work across India to demonstrate how a developing nation manages research and locational challenges. The socio-economic, ethical, and policy dimensions of WBE for SARS-CoV-2 are also discussed.

“…Esto subestima la cantidad total de personas infectadas y por tanto, hay un desconocimiento de la circulación real del virus a nivel comunitario 8,9 , situación que es mucho más seria en países de bajos y medianos ingresos entre los cuales se encuentra Chile 10 . Este escenario estimuló la implementación de un sistema de vigilancia ambiental menos costoso que el testeo persona a persona, como es la detección y cuantificación del virus en las aguas residuales 11 .…”
