Supply Systems

Intermittent water supply networks risk microbial and chemical contamination through multiple mechanisms. In particular, in the cities of developing countries, where intrusion through leaky pipes are more prevalent and the sanitation systems coverage is low, contaminated water can be a public health hazard. Although countries using intermittent water supply systems aim to change to continuous water supply systems—for example, Kampala city is targeting to change to continuous water supply by 2025 through an expansion and rehabilitation of the pipe infrastructure—it is unlikely that this transition will happen soon because of rapid urbanisation and economic feasibility challenges. Therefore, water utilities need to find ways to supply safe drinking water using existing systems until gradually changing to a continuous supply system. This study describes solutions for improving water quality in Mukono town in Uganda through a combination of water quality monitoring (e.g., identifying potential intrusion hotspots into the pipeline using field measurements) and interventions (e.g., booster chlorination). In addition to measuring and analyses of multiple chemical and microbial water quality parameters, we used EPANET 2.0 to simulate the water quality dynamics in the transport pipeline to assess the impact of interventions.

Abstract Water supply systems that operate intermittently rather than continuously are highly complex. This arises from the interaction of large numbers of internal and external factors that produce major consequences for system operation and management. Handling these problems requires understanding, and to some extent eliminating, their causes. In this paper, Lusaka Water and Sewerage Company, Zambia, is used as a case study that shows how poor governance, demographic and economic dynamics, hydrologic regime change, poor system management and operation, unplanned system extensions, limited skilled manpower, poor electricity supply and lack of customer awareness all contribute to sustaining intermittent water supply. Interdisciplinary approaches are recommended to explore interplays between governance, climate change and technical factors when developing solutions to intermittent supplies.

Domestic Water Supply

Water is essential for maintaining life, ensuring a safe and continuous supply of water, therefore, it should be given the priority for concerns. Developing countries often face a number of problems with domestic water supply systems such as treatment plants with old technologies, degraded equipment leading to inefficient treatment, and a network of degraded piping, which could cause re-pollution of treated water during transport. Pleiku city, which is located in the Central Highlands of Vietnam, has built two treatment plants and a network of water supply pipelines in the core area. An analysis of the current state of the water supply system including water supply, treatment plant and pipeline system helps identify existing problems in the system. Through mixed methods, hazards or hazardous events are identified as a basis for risk assessment by using semi – quantitative method to assess raw risk and residual risk for each hazard. Priority risks are identified to focus on proposing the possible solutions that will improve the performance and management of domestic water supply systems.
