DODOMA URBAN WATER SUPPLY AND SANITATION AUTHORITY ( DUWASA )

Dodoma Urban Water Supply and Sanitation Authority (DUWASA) is an autonomous public utility established to deliver safe, reliable water supply and sanitation services to the urban residents of Dodoma City and the towns of Bahi, Chamwino, Kongwa, and Kibaigwa. Legally grounded in the Water Supply and Sanitation Act No. 5 of 2019 — which repealed Cap. 272 of 1997 and Act No. 12 of 2009. DUWASA was declared a fully autonomous entity by order of the Minister responsible for the Water Sector on 13th February 1998, and officially inaugurated on 1st July 1998. As a Category "A" Water Supply and Sanitation Authority in Tanzania, DUWASA operates at the highest classification tier, fully covering its own operations and maintenance costs, including a portion of its capital investment requirements. Water Supply DUWASA draws water from an extensive network of groundwater sources spread across Dodoma City and its surrounding areas. The primary source is the Makutopora Well Field, comprising 17 operational boreholes with an installed capacity of 61,500 m³ per day. This is complemented by additional well fields at Nzuguni (10,032 m³/day), Ihumwa (5,517 m³/day), and Iyumbu (2,688 m³/day), which together serve key areas including the Government City at Mtumba, the University of Dodoma, Nghong'onha, and Benjamin Mkapa Hospital. Peri-urban areas including Nala, Mkonze, Zuzu, Mahomanyika, Michese, Nkuhungu, and Mpamaa are served by a further 28 operational boreholes with a combined capacity of 4,263 m³ per day, with ongoing plans to expand coverage. DUWASA currently produces an average of 79,100 m³ of water per day. Water is conveyed through a sophisticated pumping and storage infrastructure, including booster stations, collector mains, and elevated storage tanks at Kilimani, Imagi, Itega, and Kitunda, from which it gravitates to consumers across the city. In the Towns of Bahi, Chamwino, Kongwa and Kibaigwa, dedicated borehole systems and storage tanks with a combined capacity of thousands of cubic metres ensure that communities beyond Dodoma City also receive a consistent and reliable water supply. Looking ahead, the Ministry of Water is constructing a dam on the Bubu and Mkinki Rivers in Chemba District, approximately 130 km north of Dodoma, to secure large-scale, long-term water supply for the region. Sanitation Services DUWASA is equally committed to advancing sanitation across its service area. The existing sewerage network spans 122.1 km of wastewater collection infrastructure and currently serves approximately 8% of Dodoma City's population. Collected sewage is treated at four waste stabilization ponds (WSPs) in the Swaswa area, operational since the early 1980s with a combined capacity of 3,672 m³ per day. DUWASA also operates dedicated treatment facilities at the University of Dodoma (4,500 m³/day) and Benjamin Mkapa Hospital, where an automated baffle reactor handles 900 m³ per day. For the majority of residents not yet connected to the sewerage network, DUWASA supports non-sewered sanitation through faecal sludge emptying and transportation services, working alongside private operators to ensure safe disposal. To bridge the significant infrastructure gap, a major sanitation improvement project is underway to expand treatment capacity to 35,000 m³ per day a transformative investment that will dramatically improve public health and environmental outcomes for Dodoma's growing population.
