Tanzania has significant water resources, with an average available water of 2,000 cubic meters per inhabitant per year in 2012, which is expected to reach 1,400 cubic meters in 2025, given population growth. In 2010, potable water supply rates in Tanzania were 68% in Dar es Salaam, 84% in the 19 major cities, 54% in secondary cities and 57% in rural areas. Less than 20% of the urban population was connected to a sanitation network. Bukoba and Musoma are two medium-sized towns on the shores of Lake Victoria from where they fetch almost all of their water needs. With an estimated population of 350,000 in 2015 and a demand of 13,000 cubic meters of water per day in Bukoba and 28,000 in Musoma, the facilities and features of today's water systems are largely inadequate: water intakes have a limited capacity of 7,500 cubic meters per day in Bukoba and 9,700 in Musoma; the capacity of the reservoirs is 2,000 cubic meters in Bukoba and 2,500 in Musoma; the current 35-kilometer networks in Bukoba and 65 in Musoma, which are very old and degraded, only serve 70% and 60% of their population respectively. Neither city has a collective sanitation system. Part of the population uses individual or shared latrines connected to septic tanks that are rarely or not drained at all. The technical performance, maintenance, management of physical losses and billing of utilities in these cities are to be improved.
Following an initial grant of 7 million Euros in the region for water-related infrastructure, this project must secure potable water supply in quantity and in quality in the cities of Bukoba and Musoma. Construction of new water intakes, a new water treatment plant and new storage tanks are planned. The project will allow the rehabilitation and extension of treated water distribution system. In addition, pending the construction of a collection network and a treatment plant, septic tank sludge will be treated. The water utilities capacity of the two cities will be strengthened to manage the production and distribution of potable water. AFD's interventions around Lake Victoria are part of the regional strategic approach to preserving the lake's water basin.
The project has helped 250,000 people gain access to an improved drinking water system. Moreover, 5,000 cubic meters of water are saved every day by reducing network losses.
