Key Findings

  • In Ecuador’s Esmeraldas province, all three communities studied experienced intermittent water supply (IWS), but the frequency and duration of disruptions varied
  • Households experiencing more frequent water interruptions were more likely to treat their water at home to ensure safety
  • Unreliable water systems led households to distrust the piped supply, often relying primarily on bottled water instead of seeking multiple water sources
Many regions globally struggle to provide consistent access to safe drinking water, even where piped water infrastructure exists. This often manifests as intermittent water supply (IWS), where water flows only for limited periods, creating insecurity for households with connections[2][3]. While the problems associated with IWS are known – increased contamination risk and potential health issues – a detailed understanding of how specific patterns of intermittency influence people’s responses and coping mechanisms has been lacking. Most studies have relied on broad comparisons between locations, rather than rigorous analysis of the relationship between the nature of IWS and the strategies people employ to manage it. Researchers from the University of Michigan, Rutgers University, Trinity College, University of Washington and University of California Berkeley addressed this gap in a study conducted across three communities in northwestern Ecuador[1]. The research aimed to characterize household piped water intermittency – how often, for how long, and how predictably water services are disrupted – and to link these patterns to the coping strategies residents use. The study employed a mixed-methods approach, combining quantitative surveys with qualitative interviews. The quantitative phase involved collecting data from households on their water supply experiences and the methods they used to cope with interruptions. The qualitative phase involved in-depth interviews to understand residents’ perceptions of water access and quality. The findings confirmed that all three communities experienced IWS, but the specifics varied. The largest town, Borbón, even showed differences in IWS patterns between neighborhoods. Crucially, the research went beyond simply documenting the presence of IWS to quantify its impact. Statistical analysis revealed a clear association between the frequency and duration of interruptions and coping behaviors. For each additional day per week without water supply, households were 30% more likely to treat their water at home. Conversely, longer periods without water were associated with a decreased likelihood of using multiple drinking water sources – an 18% reduction for each additional day without supply. Similarly, each extra three hours per day without water increased the odds of treating domestic water by 12%. These findings build on earlier research demonstrating the widespread prevalence of IWS and its associated health risks[2][4]. Study[4] highlighted that approximately two-thirds of the global population experiences severe water scarcity for at least one month of the year, and that intermittent supply contributes to microbial contamination. The Ecuador study adds nuance by showing that the degree of intermittency is a key factor driving household responses. The qualitative data provided further context, revealing that household coping strategies are not simply reactive to water supply issues, but are also influenced by perceptions of water safety, convenience, cost, and – importantly – predictability. Unreliable water systems can erode trust in the piped supply, leading households to adopt alternative strategies that may carry their own risks and expenses. This aligns with the findings of[3], which emphasizes the need to understand the specific contexts – often low-income countries with limited infrastructure – that exacerbate contamination risks in IWS systems. The research underscores the importance of interventions focused on continuous water services and improved water management. Addressing the root causes of IWS, rather than simply focusing on coping mechanisms, is essential to reduce health risks and build trust in water infrastructure. The study also highlights the need for more detailed assessments of water supply patterns to tailor interventions effectively.
