“…(double tail) was less than 0.01, confirming a significant correlation between the simulation and calculation results. Additionally, the correlation coefficient between the simulation and calculation results is 0.999437, which is close to 1, confirming an extreme correlation [35][36][37]. As shown in Table 7, the relative error between the calculated results of Equation ( 1) and those of the numerical simulation is less than 20%, indicating that the numerical model of tailing particle sedimentation established in this experiment is relatively reliable.…”

In this study, we developed a pipeline transport model to investigate the influence of particle sedimentation factors on slurry transportation through pipelines. The particle tracking module of the software was used to simulate the transport process, and the influences on the sedimentation rate were analyzed considering the slurry concentration, particle size, and flow velocity. The established model exhibited small calculation errors. In addition, the results revealed that the proposed model is reliable for calculating the degree of influence of various factors on particle sedimentation. The effect of the particle sedimentation rate on the pipeline slurry was explored considering the particle size, slurry concentration, and flow velocity. The sedimentation rate was positively related to particle size and adversely related to the slurry concentration and flow velocity. Indeed, study on the sedimentation rate requires considering a reasonable range of particle sizes, preparing a slurry with an appropriate concentration, and adjusting an appropriate flow velocity. Numerical simulations were performed using the filling data as the background for a sample mining area. The experimental results showed optimal slurry concentration and particle size of 60% and 25.25 µm, respectively.

“…The quantity of water consumed by a household is proportional to the size of the household, and larger households tend to consume more water. 37 Given that the use of improved water comes with a cost, this might be one of the reasons why households with five or more members are more likely to use unimproved water. Similar to our results on the association of household size with sanitation, other studies have reported that the use of unimproved toilet facilities is less likely among larger households.…”

“…The results of our study are similar to the results of another nationally representative study19 that used data from the 2014 Ghana DHS,18 in which households with more members were more likely to have access to improved toilet facilities but not access to improved drinking water. The quantity of water consumed by a household is proportional to the size of the household, and larger households tend to consume more water 37. Given that the use of improved water comes with a cost, this might be one of the reasons why households with five or more members are more likely to use unimproved water.…”

ObjectiveThe government of Ghana has targeted universal access to safe drinking water by 2025 and elimination of open defecation by year 2030. This study explored the use of unimproved drinking water and unimproved sanitation and assessed their association with demographic factors.DesignThis was a secondary data analysis of the 2017 Ghana Maternal Health Survey, a nationally representative cross-sectional survey. Open defecation households were mapped to show regional differences. Weighted logistic regression was used to assess the association of demographic variables with use of unimproved drinking water and unimproved toilet facilities.SettingGhana.ParticipantsA total of 26 324 households were included in the analysis.Primary and secondary outcome measuresUse of unimproved drinking water and unimproved toilet facilities.ResultsOut of the 26 324 households, 8.9% used unimproved drinking water while 81.6% used unimproved sanitation. Open defecation was practised by 15.2% of Ghanaian households, with a prevalence of 58.8%, 6.7% and 12.5% in the Northern, Middle and Coastal zones, respectively. In the multivariate analysis, rural households (p<0.001), households with more than five members (p<0.001), households with heads less than 25 years (p=0.018), male-headed households (p<0.001) and household heads with no/low level of education (p<0.001) were significantly associated with drinking unimproved water. Also, rural households (p=0.002), households in the Northern zone (p<0.001), single-member households (p<0.001), households with heads less than 25 years (p<0.001) and household heads with no/low level of education (p<0.001) were significantly associated with using unimproved toilet facilities.ConclusionThe target of universal access to safe drinking water by 2025 and elimination of open defecation by 2030 seems impossible to be achieved if appropriate measures are not implemented. We recommend that state authorities, health partners and non-governmental organisations support local-level sanitation plans and strategies.

A Framework for Archive Demand Management Strategies: A Pilot Study on Water Use in a Low-Income Brazilian Area

This study presents a pilot study in suburban households in Salvador, Brazil, inserted in the context of a framework developed to aid water demand management strategies. The framework aims to understand the barrier of subjectivity while identifying consumption habit patterns in households. Six key sets of components create the framework architecture: (1) characterization of the area based on: context, climate, population/area, population growth rate, and water management challenges; (2) a survey to obtain socio-demographic and physical property data of the sample; (3) smart metering and data processing systems to monitor sample water end use; (4) determining daily consumption patterns; (5) analyzing qualitative data through theoretical consumption models to identify relevant variables for the next step; and (6) construction of representative mathematical models of consumption for each daily practice (this item was not included on pilot). It provides a starting point to understand how water demand management strategies can be supported at the user and decision-making level. As a result, improvements to the interview guides used in the pilot were suggested. Furthermore, customized measures to promote rational water consumption were identified in the study area, and policies could be proposed.
