In Ontario, Canada, Public Health Inspectors (PHIs) are responsible for enforcing standards for small drinking water systems (SDWS), which often serve rural and resource-limited communities. This study examined the facilitators and barriers influencing the effectiveness of SDWS oversight from the perspective of frontline PHIs. An online survey was distributed to all 29 public health units in Ontario, yielding 28 responses (n = 28). The survey data underwent inductive thematic analysis to identify the key factors affecting program delivery and public health protection. Five principal themes were identified: (1) PHI knowledge and training, (2) operational and program support, (3) technological and field capacity, (4) challenges encountered by system owners and operators, and (5) legislative and regulatory compliance. Respondents indicated that, although regulations provide a helpful framework, limited training, resource constraints, and inconsistent enforcement hinder effective oversight. The findings indicate that improvements in inspector training, technological and field resources, and inter-jurisdictional coordination are fundamental for advancing the SDWS program. Strengthening SDWS effectiveness requires focused interventions in training, infrastructure, and coordination. Practitioner-identified priorities should inform future policy and funding allocation, stressing the importance of integrated, decentralized water governance.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"99 ","pages":"Article 102154"},"PeriodicalIF":4.4,"publicationDate":"2026-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146188358","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The WSS are encompassed within the concept of ‘basic sanitation,’ which includes a comprehensive approach to policy interventions aimed at protecting public health and the environment. This broader definition incorporates potable water supply, wastewater collection and treatment, solid waste management, and urban drainage and stormwater management (UDSM). However, these services have evolved disproportionately, with a focus on water supply and wastewater treatment. As a result, despite the critical importance of UDSM in urban areas, many Brazilian cities lack these services, leaving both populations and the environment vulnerable to adverse impacts. Although the reasons for this imbalance among services might be justified according to the priority of indispensable services, the UDSM has also proved essential to a broader concept of urban security, health, and sustainability. This article explores the asymmetries between UDSM and other WSS within Brazil's new regulatory framework, following the enactment of Law No. 14,026/2020. The findings reveal that, in the absence of institutional drivers rooted in the historical asymmetries observed during the consolidation of the National Water and Sanitation Policy (NWSP), UDSM services remain marginalized and face inertia in public policy. If this trend persists, UDSM services are unlikely to follow the same trajectory of improvement seen in other WSS, ultimately undermining the goal of achieving universal access to basic sanitation.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"98 ","pages":"Article 102114"},"PeriodicalIF":4.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145614474","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper addresses the research gap concerning the economic implications of local flexibility markets where the distribution system operator (DSO) acts as the single buyer. We propose a procurement mechanism that embeds counterfactual investment valuation into a pay-as-bid clearing rule and determines equilibrium through Marshallian surplus maximization. The methodology is illustrated with numerical case studies that compare procurement outcomes under complete and incomplete supply offers. Results show that, even when some bids exceed the DSO's valuation threshold, accepting them can increase welfare, thereby delivering efficient and rational price signals. These findings challenge the view that monopsony inevitably distorts markets: when disciplined by transparent and auditable valuation, it can support neutrality and efficiency. The framework aligns with the forthcoming Network Code on Demand Response and Distribution Network Development Plans disclosed, offering regulators and DSOs a practical tool for market-based procurement and a ready candidate for regulatory sandboxes.</div></div>","PeriodicalId":23554,"journal":{"name":"Utilities Policy","volume":"98 ","pages":"Article 102086"},"PeriodicalIF":4.4,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145327366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to bridge the gap by conducting a systematic literature review that identifies and analyzes the fundamental dimensions of water tariffs from a supply-side sustainability perspective, as articulated in contemporary literature spanning domestic, industrial, and agricultural sectors across various countries and regions. These insights have the potential to enhance the supply-side approach to water management. Employing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline and a Mixed Methods Appraisal Tool (MMAT), we scrutinized 16 studies. Through thematic analysis, we discerned six key interconnected dimensions of water tariffs: affordability, efficiency, financial sustainability, regulatory framework, conservation incentives, and the sustainability of water resources, which were further delineated into 11 sub-themes. The originality of this study resides in articulating these supply-side conceptual dimensions, synthesizing disparate themes into a cohesive framework, and illuminating critical trade-offs, particularly between affordability and financial sustainability.
