This research aimed to identify a tool to objectively analyse the performance and the environmental contextualisation of sewer systems (SwSs) and wastewater treatment plants (WWTPs). This procedure performs assessment by calculating performance indices which could be subsequently applied to SwSs and WWTPs with different characteristics. The proposed tool can be applied conveniently over the years by managers of integrated urban water management systems for the analysis of different realities also allowing the evaluation of the effects of upgrades carried out during the management phases. The proposed analysis allows the optimisation of SwSs and can profitably guide the choice and the priority among possible interventions for the sewerage infrastructure and WWTPs providing a verification and evaluation protocol as well as a financial planning tool.

The widespread discharge of emerging micropollutants (EMs) into sewer systems has raised serious environmental concerns throughout the world. However, the transformation mechanisms underlying the accumulation of EMs in sewer sediments remain largely unexplored. This study investigated the transformation fate and mechanisms of chloroxylenol (PCMX) in sewer sediments.

Evaluating groundwater infiltration (GWI) in sewer networks is essential for managing network capacities, especially amid growing pressures on network maintenance and operation caused by increasing domestic and storm water inputs. Despite this significance, GWI assessments have received limited attention, especially at large scales. In fact, no previous study has comprehensively evaluated sewersheds based on GWI scores.

Objectives: Although wastewater monitoring for virus detection has increased in communities worldwide, public awareness, understanding, questions, and concerns about wastewater monitoring are largely unknown. We assessed awareness, knowledge, and support for wastewater monitoring for detection of viruses and bacteria among US residents and elicited questions and concerns from residents about its use.
Methods: We conducted a survey among a racially and ethnically diverse sample of residents in Colorado, Maryland, Missouri, Nebraska, and Texas to assess awareness, knowledge, and support of wastewater monitoring.

Ammonia (NH), a naturally occurring disinfectant in wastewater, plays an important role in inactivating pathogens, including viruses. Despite its importance in non-sewered sanitation systems, the inactivation rate constant attributed solely to ammonia ( [Formula: see text] ) remains unclear, owing to the diverse range of disinfection conditions in existing studies. Determining [Formula: see text] is critical for quantifying the contribution of ammonia to viral inactivation and distinguishing it from other environmental factors.

The stability of microbial communities within sewer systems is essential for maintaining effluent quality and infrastructure longevity. However, the functional consequences of viral interactions with biofilms remain poorly characterised. This study examines the effects of bacteriophage MS2 adsorption on biofilm structure, metabolism, and pathogenic potential in a simulated 1 km sewer pipeline.
