ABSTRACT There are various factors in Dili’s water system responsible for the water scarcity problem in the city. Hence, there is a need for strategic plans which could be used as guidelines in improving its water system. The objective of this study was to formulate a strategic plan for water resource management in Dili. The process commenced with the identification of external and internal factors. The Analytical Hierarchy Process (AHP) was used to weight the score at the input stage. The alternative strategies were formulated with the Strengths, Weaknesses, Opportunities, and Threats (SWOT) matrix. Furthermore, the Quantitative Strategic Planning Matrix (QSPM) was used to select the priority strategy at the decision stage. Based on the results, a total of 13 internal and 13 external factors were identified, while five alternative strategies formulated. Moreover, the selected strategy as the priority for implementation has the capacity of developing the water resource management infrastructure in Dili, as well as improving the water supply system performance in meeting the urban water demand.

Hydrogeologists and other water experts agree on that the effective groundwater management requires: firstly, a good understanding of the aquifer system; secondly, identification of practical measures to control abstraction; and thirdly, improvement in groundwater resource through artificial recharge. A 16 years’ pumping test and drilling lithology data and productive 29 wells were used to characterize the aquifer parameters of the Hawassa City, Ethiopia. The aquifer system was characterized physically, potentially, spatially, quantitatively, and qualitatively using AquiferTest software by applying Moench method to pumping test response data considering the basic assumptions in the model. Weathered and fractured pumice, basalt Scoriaceous rocks, fine-to-coarse-grained sand, and weathered ignimbrites are major water-bearing formations found from the analysis. High porosity and permeability due to these fractures are found to be a risk for the easy contamination of the ground water from surface wastes especially at the shallow aquifer water areas. Spatially, the southern corner and the lake shore of the city were identified as a huge potential area. Percentage of recovery results are 95–100% and transmissivity varies from 4.77 × 10−4 m2/s to 1.75 × 101 m2/s. This follows the general pattern of increasing value from east to west, that is, the value increases from the upper part of the basin to the lower. Moreover, the annual ground flow vector map of the area was developed using static water level data to see the direction of subsurface flow in the area. Accordingly, a large magnitude of water flowing from the central and west directions to the lake shore is identified showing similar profile with the surface flow.

Chile is famous for being the longest country in the world from north to south. It means it ranges from polar to desert conditions, water being one of the main limiting factors. In fact, Chile stores a high amount of water (695 mm y−1), but people are not located in the regions where water is more abundant (e.g. in the south). This territorial imbalance is accompanied both by a global context of climate change in which water will be presumably scarcer and by the effects of the current economic activities that are progressively more demanding in water consumption. In this work, we have compared both the current and future availabilities of water for the different regions of Chile in order to provide relevant and useful information on the water balance for land planners. The Metropolitan and Valparaíso regions (Mediterranean climate) along Antofagasta, Atacama, and Tarapacá regions (desert climate) showed the lowest mean values of water availability from 1970 to 2000 (<125 m3 person y−1). In addition, both the optimistic and pessimistic projections for 2050 forecast a significant increase in the aridity of these two central regions, where the crucial axis between the two most important cities (Santiago and Valparaíso) is located.

Fluorosis continues to be an endemic problem in Yemen. More areas are being affected by fluorosis in different parts of this country. The present study aims to identify the intensity and the spatial extent of fluoride concentration in groundwater of the southern part of the upper Wadi Rasyan, Taiz, Yemen. 93 sampling points were selected; the sampling included all types of sources of groundwater and all types of aquifers. The results show that 71% of samples exceed the WHO drinking water guidelines value of 1.5 mg/l, and there are wide variation for groundwater’s content of fluoride in the same aquifer (whether, volcanic and alluvial) and in the same of groundwater type, and these variations between the different water types or between the different depths of water (alluvial and volcanic aquifers) are not significantly different. The high concentration of fluoride in groundwater of the volcanic aquifer is likely because of the nature of geology formations by the water-rock interaction result of long-time residence of water in contact with the geology formation. The high concentration of fluoride in the alluvial aquifer likely resulting the waste of urban and industrial activates sources, the over exploration of groundwater, the arid climatic and the activities agriculture.

In Colombia, a country with great climatic diversity, the water balance is affected in one way or another by climate change depending on the region. Thus, there may be increases and decreases in precipitation and, in all cases, a huge increase in temperature. This document presents some studies carried out in different areas of the country regarding the effects of climate change on water resources, including its influence on hydroelectric power generation, some changes in the water balance in arid areas, and the opportunity to ensemble climate change scenarios. Likewise, it outlines a possible future water supply-demand relationship, where supply is associated with a change in the water balance and demand with some crops, activities, and sectors that need water to survive. This allows to estimate some future status indices to see the overall picture of climate change in connection with the country’s water resources.

Access to affordable and clean water has remained a challenge globally. Most states in Africa states have championed the provision of water to its citizens through state driven approaches. Despite the evidence that community water supply has contributed positively more than any other single approach to provision of water supply in Africa, it is still regarded as an informal approach. Most states in Africa still prefer other conventional approaches like Concession and Affermage in Francophone Africa and Commercialization through Management contracts in Anglophone Africa at the expense of the community water management. Either the state has not used the right approach or has neglected the community. Using evidence from Kenya, Tanzania, Malawi, Ghana and Nigeria, the paper has argued that the failure by the governments to acknowledge the disconnect between the community needs and state priorities has been responsible for the poor state of water provision in Africa.

Innovative digital developments from industry like autonomous machine controls based on intelligent data acquisition, collection and evaluation, promises better adapting municipal infrastructure systems to changing conditions. When the technology initiative KOMMUNAL 4.0 was developed as an idea in 2015, digitalization was not a central topic in water management. As Industry 4.0 was present everywhere in the media, the idea of transferring suitable parts of the basic idea of Industry 4.0 to municipal water management was born. In particular, it was necessary to implement consistent IT and IoT communication at all levels of water management tasks. The aim was not only to create a uniform structure for networking a wide variety of applications, but also to round off KOMMUNAL 4.0’s complete range of services with IoT for existing and newly developed products and solutions. Regardless of whether it concerns measurement and data technology applications, smart machines, SCADA or asset management systems, all application solutions contain a standardized network core that guarantees standard data communication and also complying with safety and cybersecurity requirements.

ABSTRACT Regulation, including statutory land use planning law, is seen as an important way to encourage the adoption of water sensitive urban design (WSUD) practices. Despite this, there has been little empirical investigation of how statutory land use planning influences the uptake of WSUD practices, and how planning frameworks could be redesigned, to better support WSUD. The influence of statutory planning on WSUD practices was investigated in four case studies, two from Victoria and two from Western Australia. The case studies considered how statutory planning influenced four discrete components of WSUD practice. In the case studies, statutory planning did encourage the adoption of WSUD practices. The capacity of statutory land use planning to encourage WSUD practices was enhanced when statutory planning included specific quantitative targets and when it encouraged the adoption of these practices at the localised, street scale. The research also found that statutory land use planning interprets the WSUD concept, by encouraging specific practices. These practices, in turn, reinforce our assumptions about what WSUD might be.

ABSTRACT The objective of this study was to evaluate the effectiveness of drinking water quality verification monitoring as a means of improving preventive measures on drinking water quality management in regional New South Wales (NSW), Australia. Water sampling and E. coli detection data were obtained from the NSW Drinking Water Database. Statistical analysis was performed using Incidence Rate Ratios to compare the relationship between the proportion of samples collected to the tests allocated based on population served (sampling adequacy), E. coli detection and the relationship between sampling adequacy and E. coli detections over time. Sampling adequacy and E. coli detections significantly improved during the study period. Sampling adequacy was significantly lower in smaller populations (IRR = 0.83, p = 0.036). E. coli detections were significantly increased in smaller communities (IRR = 4.3, p = 0.01) and in summer (IRR = 2.7, p = < 0.001). There was a strong inverse correlation between improved sampling adequacy and decreased E. coli detections (Spearman’s rho = −0.821; p < 0.0001). This research has highlighted the value of continued assistance to water utilities in the implementation of drinking water management systems to improve drinking water safety.
