This work delves into the role of urban water technologies in bolstering heat-resilient infrastructure across the region. This work also assesses urban water technologies that can contribute to the development of heat-resilient infrastructure in urban areas. This involves examining innovative approaches that can help mitigate the impacts of extreme temperatures on water infrastructure and enhance its resilience to climate change. They include green infrastructure, decentralized water systems, and advanced cooling technologies that have the potential to improve the resilience of urban water infrastructure to heat stress and extreme temperatures. Through empirical studies, this study underscores the imperative for proactive measures to enhance urban resilience in the region. The implications of this work offer practical insights for policymakers, urban planners, and stakeholders to bolster climate resilience in the region, emphasizing the role of water technologies in mitigating risks and enhancing adaptive capacity.

The need for improved drinking water treatment methods is discussed by using Brazil as a case study. Brazil’s agriculture is intensive, and pesticide consumption is high, while current drinking water treatment methods are inadequate for effectively removing pesticides. Available data on surface water contamination in Brazil show widespread occurrence of pesticides in natural waters, thereby putting pressure on the water treatment system and threatening the quality and safety of drinking water. Pesticide concentrations in drinking water frequently exceeded the maximum permissible concentrations if EU regulations (0.1 μg/L) were applied, highlighting the need for improvements in drinking water treatment. (Advanced) drinking water treatment for the removal of pesticides has been intensely researched over the past decade. However, challenges such as high cost and energy intensity, as well as the production of hazardous byproducts, must be assessed critically. Safely managed drinking water is crucial to the sustainable development of low- and middle-income countries and can be achieved only through appropriate technology. Engineered biofiltration has been put forward as a sustainable alternative to conventional and advanced drinking water treatment.

As a result, public health has suffered and environmental degradation has continued. Social enterprises that use innovative business models to provide on-site sanitation services, also known as sanitation enterprises, are considered an emerging solution. However, sanitation enterprises have not yet successfully replaced public provision at scale. This work explores the barriers that sanitation enterprises encounter in lower- and middle-income countries. Q-Method, a mixed-methods approach that assesses social perspectives on an issue, is used to evaluate major barriers and groups of dominant perception for 19 sanitation enterprises operating across 20 countries. A total of 25 mutually exclusive, collectively exhaustive barriers are identified, ranging from affording capital expenses to navigating political corruption. The results show that most of the identified barriers fall into the financial barrier category, with reaching economies of scale being the greatest obstacle for sanitation enterprises. On the basis of these results, the premise of independent profitability underlying the sanitation enterprise value proposition should be reevaluated. Four enterprise types are proposed and can explain half of the variance among the sanitation enterprises studied. The context of a sanitation enterprise, including its countries of operation, size, customer base, sources of revenue, and section of the sanitation value chain, influences the barriers that the enterprise encounters. This research underscores the crucial role of context in influencing barriers for sanitation enterprises, emphasizing the need for investment and for policy makers to take these contextual dimensions into account.</p><p >This study asks sanitation enterprises in lower- and middle-income countries what are the barriers they face in becoming financially sustainable.</p>","PeriodicalId":93847,"journal":{"name":"ACS ES&T water","volume":"4 9","pages":"3986–3995 3986–3995"},"PeriodicalIF":4.8,"publicationDate":"2024-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsestwater.4c00274","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142228258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wastewater surveillance revealed that Influenza A virus (IAV) and respiratory syncytial virus (RSV) sewage concentrations exhibited an upward trend from October 2022 in both cities but with distinct epidemic trajectories. In Dalian, IAV and RSV sewage concentrations both peaked in early December, followed by a rapid decline since the emergence of COVID-19 on November 23, 2022. In Benxi, two bell-shaped curves were observed for IAV and RSV sewage concentrations, both peaking in mid-December of 2022, even though severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) emerged in wastewater on December 8, 2022. After a rapid decline in SARS-CoV-2 sewage concentrations in January 2023, a new wave of IAV in wastewater occurred between February and early April in both cities, followed by a surge of SARS-CoV-2 RNA in early May.
