“…Interestingly, although basic drinking water services are estimated to have lower pathogen concentrations than surface water or unimproved sources 24 , JMP drinking water service level was only weakly associated with anticipated drinking water harm (Extended Data Table 3). Further, in countries with more than 95% basic drinking water service coverage, there was considerable diversity in anticipated harm, supporting the notion that perceived risks are strongly in uenced by factors other than objective water quality 20 . These data suggest that addressing the global water crisis will require targeted interventions that address inequalities in access to safe drinking water and promote greater trust through improvements in water governance, knowledge dissemination, and relationship building [36][37][38] .…”

“…These ndings are important because human behavior and health decision-making are largely driven by experiences, perceptions, and attitudes 3,20 . Individuals who perceive their water to be dangerous or of suboptimal quality are more likely to avoid or not pay for piped water 26,27 , consume bottled water 28,29 , and substitute sugar-sweetened beverages for water 23,30 , which in turn have negative consequences for the sustainability of water services as well as human and environmental well-being.…”

“…Survey data on human perceptions and experiences are increasingly appreciated for their ability to capture multiple factors that in uence an individual's behavior 19 . Regarding water quality, these include organoleptic properties (e.g., taste, smell); (dis)trust in local, regional, and national institutions; knowledge about and familiarity with water management and treatment practices; attitudes toward diverse contaminants; and the beliefs and values of those within an individual's social network 3,20 . Quantifying people's experienced and anticipated harm from drinking water in surveys is also useful because results can be disaggregated to the individual or household level 21 .…”

Poor drinking water quality is a global crisis that affects billions of individuals. Understanding who is most impacted is necessary to develop programs that ensure sustainable, reliable, and resilient access to safe water. But current water indicators do not capture people’s experienced and anticipated harm from drinking water, which means we have had limited understanding of how individuals conceptualize, navigate, and are affected by their water environment. Here, we analyzed data from nationally representative surveys undertaken in 142 countries in which people reported their recent experiences and future expectations of harm from drinking water. Prevalence of reported harm from drinking water in the prior two years was 14.5% (range: 0.8%–54.3%). More than half of the world’s population (54.4%) anticipated that they would experience serious harm from their drinking water in the next two years. Greater public sector corruption was associated with greater anticipated harm from drinking water, even when adjusting for indicators of water infrastructure and economic development. Disparities in anticipated harm across countries and by gender and household location indicate that targeted policies are required to address risk perceptions, equitably improve access to safe drinking water, and increase trust in institutions that supply and regulate water services. The addition of experiential survey data to global data collection efforts will complement objective water quality data and provide novel insights about which strategies will most effectively advance progress toward safe drinking water for all.

“…FF scheduling evaluates represented by DEL from the FF1 in Equation ( 6), supplied by the CBS, then with FF2 from Equation (8) the chlorine supply is assured with the least mass injected. TMI = ∑ Q (i,t) ×CI (i,t) (7) where TMI = sum of all chlorine mass injected on the WDN and converted to kg/day, Q CBS i = flow passing thru CBS in the node i at time t. CI CBS i = disinfectant mass added at disinfection location i at time t. Then: FF2 = DEL + TMI (8) where FF2 = fitness function that seeks to reduce the chlorine mass injection but still guaranteeing FRC in the consumer nodes, TMI = total mass injected by CBS, it is obtained with the toolkit of EPANET for MATLAB and is properly adapted with flow units. The Same FF1 and FF2 are used for both GA and PSO optimization.…”

“…Water utilities to supply the minimum Free Residual Chlorine (FRC) at the end of the WDN, add elevated doses of disinfectant at the exit of the DWTP [6]. Reducing chlorine demand from water utilities derives less chlorine manufacture and energy consumption, and a better perception from consumers in tap water safety improves the quotes collection for water utilities; furthermore, there will be a reduction in bottled water and thus a lower environmental impact [7]. This is important because chlorine gas is commonly manufactured by electrolysis which in some of its variances uses at least 3560 kWh/Ton Cl 2 [8].…”

Optimal Placement and Operation of Chlorine Booster Stations: A Multi-Level Optimization Approach

Chlorine demand as a disinfectant for water utility impacts on unintended energy consumption from electrolysis manufacture; thus, diminishing the chlorine consumption also reduces the environmental impact and energy consumption. Problems of disinfectant distribution and uniformity in Water Distribution Networks (WDN) are associated with the exponential urban growth and the physical and biochemical difficulties within the network. This study optimizes Chlorine Booster Stations (CBS) location on a network with two main objectives; (1) to deliver minimal Free Residual Chlorine (FRC) throughout all demand nodes according to country regulations, and (2) to reduce day chlorine mass concentration supplied in the system by applying an hour time pattern in CBS, consequently associated economic, energy and environmental impacts complying with regulatory standards. The application is demonstrated on a real-world WDN modeled from Guanajuato, Mexico. The resulting optimal location and disinfectant dosage schedule in CBS provided insights on maintaining disinfectant residuals throughout all the WDN to prevent health issues and diminishing chlorine consumption.

Water is the lifeblood of our Earth, and sustainable water consumption is the key to preserving this scarce resource for future generations and upholding environmental sustainability. In this study, we investigate the relationship between environmental knowledge (EK), environmental policies and regulations (EPR), attitudes toward water resource management programs (APWRMP), perceived water quality (PWQ), and sustainable consumption (SC), enriching the existing literature by integrating the theoretical framework of the theory of planned behavior (TPB) alongside water management program (WMP) concepts. This integration forms a comprehensive model clarifying the influences on SC. Furthermore, this study investigates these relationships within the specific context of select regions in China, addressing a geographical gap in the current literature. With a sample size of (N = 336) participants, we employ partial least squares structural equation modeling (PLS‐SEM) to explore the complex relationships within the proposed model. The finding confirms the hypothesized associations, validating the substantial positive impact of EK and EPR on APWRMP and SC. Additionally, we observe that PWQ notably strengthens the link between the perception and attitude of villagers toward SC of water. Our study explains the multifaceted dynamics underlying individuals' behavior and attitude in making decisions concerning sustainable water consumption.
