Abstract: This study addresses the critical knowledge gap in systematic assessment and maintenance of existing rural water infrastructure in “sub-Saharan Africa,” where other studies focused primarily on access expansion rather than condition monitoring of operational systems. A comprehensive Inf [...] Read more
Abstract: Agriculture contributes 28.9% of Gross Domestic Product; about USD 1 Billion to total export value and employs about 65% of Tanzanians. Identifying opportunities for enhancing profitability of the sector is paramount to informing choices of sustainable pathways. In the absence of such information [...] Read more
Abstract: Earthfill dams are vital for water supply, irrigation, and flood control, but their safety can be threatened by structural weaknesses and poor maintenance. This study evaluates the safety of the Mtibwa Sugar Estates Earthfill Dam in Turiani, Morogoro Region that supports irrigation and eco [...] Read more
Abstract: Despite substantial global infrastructure investments, water distribution systems in tropical coastal urban environments continue to experience losses exceeding 30-40%, significantly above the international benchmark of 15%, primarily due to inadequate existing static optimization models th [...] Read more
Abstract: Water contamination by heavy metals poses serious environmental and public health threats, particularly in urban and agricultural regions where human activities intensify pollution. This study aimed to determine the levels of heavy metal contamination in urban tributaries along Musoma and Ta [...] Read more
Abstract: Chlorine decay in water distribution systems is a critical challenge that impacts disinfection efficiency and public health. This study systematically investigates the effects of pH, flow rate, pipe length, and stagnation time on chlorine residual loss through a controlled experimental framework. [...] Read more
Abstract: District Metered Area (DMA) systems promoted as a strategy for reducing Non-Revenue Water (NRW) and improving operational efficiency in urban water supply networks, yet their financial viability in Sub-Saharan Africa remains uncertain. This study assessed the economic feasibility of implementin [...] Read more
Abstract: This study assessed stakeholder engagement in planning and monitoring the performance of water supply projects at the Songea Water Supply and Sanitation Authority (SOUWASA) in Tanzania. Employing a mixed-methods research design, the study combined both quantitative and qualitative approaches. Data [...] Read more
Abstract: Rapid urbanization in cities like Dar es Salaam has led to increased stormwater runoff due to expanding impervious surfaces and insufficient drainage systems. The Water Institute, one of the region’s fastest-growing institutions, is also experiencing these pressures. This study investigates [...] Read more
Abstract: Climate change significantly threatens rural water supply infrastructures, compromising water quality and availability while increasing community vulnerability. This study evaluated socio-cultural roles in behavioural adaptation for sustaining rural water supply for climate change interventio [...] Read more
Abstract: Water security in rural Tanzania is endangered not only by environmental pressures but also by the behaviors, perceptions, and norms shaping everyday water use. This study applied the RANAS model of behavior change to assess behavioral drivers of water insecurity in Lake Bassotu, complemented by [...] Read more
Abstract: The race of attaining adequate sanitation services by 2030 remains a myth in Tanzania since the faecal sludge management systems lags far behind wastewater management systems. The case should have been vice-versa since massive amount of faecal sludge is generated in urban settings as compared t [...] Read more
Abstract: The health of river ecosystems is increasingly threatened by human activities such as agriculture, urbanization, and industrialization. This study evaluates the ecological status of the Lukosi River Catchment (LRC) in Kilolo District, Iringa, Tanzania, using macroinvertebrates and riparian v [...] Read more
Abstract: Despite sustained investments in Tanzania’s urban water sector, challenges persist in ensuring consistent and high-quality service delivery, particularly in densely populated areas like Ubungo District, Dar es Salaam. This study uses a mixed-methods approach to investigate the key factors inhib [...] Read more
