TANZANIA URBAN WATER SUPPLY AND SANITATION SERVICES: CHALLENGES AND THE NEED FOR A FRESH APPROACH
TANZANIA URBAN WATER SUPPLY AND SANITATION SERVICES: CHALLENGES AND THE NEED FOR A FRESH APPROACH Locations Themes Projects By Eng. Clement KIVEGALO: Consulting Engineer (CE 597) Urbanization: A Challenge and an Opportunity Tanzania is urbanizing at a remarkable pace, with cities expanding faster than the systems designed to support them. Today, nearly 40% of the population lives in urban areas. It is projected that the population will be more than double by 2050, placing unprecedented pressure on housing, water, sanitation, and urban infrastructure. In Dar es Salaam, one of the fastest-growing cities in the world, the population is on a clear trajectory towards megacity status, expected to exceed 10–12 million by 2030 and surpass 20 million by 2050. This is not merely a demographic shift; it is a defining national development challenge that will shape the country’s economic and social future. Yet this rapid urban expansion is not being matched by a commensurate evolution in service delivery systems. The pace, scale, and complexity of urban growth are outstripping the capacity of existing water supply and sanitation infrastructure, exposing deep structural weaknesses in how services are planned, financed, and managed. There is an uncomfortable truth we must confront: urban water supply and sanitation services in Tanzania are no longer keeping pace with reality. While demand continues to surge as a result of rapid urbanization, population growth, industrial expansion, and rising service expectations, service delivery systems are steadily falling behind. The question is no longer whether reform is needed; the real question is whether we are bold enough to pursue it. On the other hand, there is a question of mindset. Most utilities consider urbanization as merely a challenge while it can also be seen as a commercial and institutional opportunity. It expands demands, broadens the revenue base, and creates the scaled needed for efficient and financially sustainable water service delivery. The task before utilities is to organize themselves well enough to benefit from this growth. Lessons from RUWASA Experience History teaches us that meaningful development never happens without disruption. As the “Father of Classical Physics,” Isaac Newton, observed, systems remain unchanged unless acted upon by an external force. Similarly, one of the most influential scientists of the 20th century, Albert Einstein, famously warned against the futility of repeating the same actions while expecting different outcomes. Yet, this is precisely what is happening in the urban water sub-sector whereby existing structures that are increasingly becoming unfit for the purpose, are preserved while hoping for better results. We have seen before that bold thinking delivers results. The reforms initiated by the Ministry of Water in 2019, culminating in the establishment of the Rural Water Supply and Sanitation Agency (RUWASA), fundamentally transformed rural water service delivery. That shift required questioning long-held assumptions, challenging institutional arrangements, and making politically difficult decisions, thanks to the 5th and 6th Presidents of the United Republic of Tanzania who took bold decision to change the then long-standing “status quo”. Today, few would argue against its strategic importance. So why are we hesitant to apply the same courage to urban water supply and sanitation services? Current Performance of Urban Water Utilities Evidence from the Energy and Water Utilities Regulatory Authority (EWURA), the Controller and Auditor General (CAG), and Ministry of Water performance reviews paints a worrying picture: declining operational efficiency, high levels of Non-Revenue Water (NRW), poor cost recovery, weak asset management, overstretched infrastructure, and limited investment in sanitation. Many utilities are struggling to meet even basic technical and financial sustainability benchmarks. These are not temporary setbacks; they are structural signals of a system increasingly misaligned with the scale, speed, and complexity of urban growth. EWURA reports consistently show that while a few large utilities demonstrate relative strength, a significant number of small and medium urban utilities continue to underperform in key areas such as continuity of supply, sewerage coverage, billing efficiency, collection efficiency, and debt servicing capacity. According to EWURA, 54 out of 83 urban water utilities, nearly two-thirds, fail to meet even basic service and cost-recovery standards, exposing a system under severe strain. Many remain dependent on government subsidies simply to sustain operations, let alone expand infrastructure. Thoughtful Ambition: The Case for a National Water Grid Tanzania is pursuing an even bigger national ambition: the long-term vision of creating an interconnected national water grid, where multiple water sources across the country are linked to serve both urban centers and rural communities more reliably and efficiently, much like the national electricity grid. This is a transformative idea. It recognizes that water security can no longer depend solely on isolated town-based or village-based sources, especially in the face of climate variability, rapid urbanization, and growing demand. Undeniably, the ambition of creating the interconnected national water grid cannot be effectively delivered through a fragmented institutional model where each utility operates largely as an independent island. The national water grid requires strategic planning of bulk water production, transmission, storage, and inter-basin connectivity at a much higher level. It demands stronger governance of shared infrastructure, clearer asset ownership, professional management of bulk supply systems, and financing models capable of supporting large-scale strategic investments. In short, it requires institutions designed for integration and not fragmentation. The current model of semi-autonomous Water Supply and Sanitation Authorities (WSSAs), introduced in the late 1990s, may have been fit for purpose at the time. But nearly three decades later, it is time to ask a hard question: has “autonomy” truly delivered? Has it produced financially viable, efficient utilities, or has it created a fragmented landscape of small entities duplicating overheads, struggling to scale, and diluting accountability? Aren’t we preserving institutions for their historical value rather than their present performance? In a context where most utilities cannot even cover basic operational costs, autonomy without performance begins to look less like reform and more like drift. Clustering as an Intervention to Rescue Inefficient Small Town WSSAs Meanwhile, on its pursuit to improve service delivery in some smaller towns, the Ministry of Water is implementing what is commonly referred to
