Prime Minister Kassim Majaliwa has officially launched the construction of the Kidunda Dam, a major infrastructure project aimed at improving water supply and power generation in Tanzania.
The ceremony, which took place on March 5, 2025, marked a significant milestone in the government’s efforts to address the growing demand for water in key regions, including Dar es Salaam, Pwani, and Morogoro.
The Kidunda Dam, located in the Coast Region, will have the capacity to store 190 billion liters of water, making it one of the largest water storage facilities in the country.
The project, which is being funded through domestic resources, is estimated to cost TZS 335.8 billion and is expected to be completed in several phases. Currently, the project is 28% complete, with ongoing efforts to ensure its timely finish.
The dam is a critical part of Tanzania's long-term strategy to ensure a reliable and consistent water supply for its growing population and industries.
The government has prioritized the development of water infrastructure to address the challenges faced by residents and businesses in urban areas, especially during dry spells.
The Ruvu River, which flows through several key regions, will benefit significantly from the project, as it will guarantee a stable water flow even during periods of drought.
“Ensuring a steady supply of water is essential for the growth of our cities and industries. This project will not only secure water for our homes and farms, but it will also contribute to our energy needs,” said Prime Minister Majaliwa during the groundbreaking ceremony.
He emphasized the importance of sustainable water management and the role of large infrastructure projects like the Kidunda Dam in improving the quality of life for Tanzanians.
In addition to water storage, the Kidunda Dam will also include a 20-megawatt power generation plant. This plant will produce electricity that will be fed into the national grid, helping to meet the increasing demand for energy across the country.
The power plant will be connected to the grid through a 101-kilometer transmission line that will run from Kidunda to Chalinze, further strengthening the nation’s energy infrastructure.
The construction of the dam will also involve the building of essential roads. A 75-kilometer gravel road will be constructed from Ngerengere to Kidunda, improving accessibility to the area and facilitating the transportation of materials and workers.
This infrastructure development will not only support the dam project but will also benefit surrounding communities by improving local transportation networks.
Once completed, the Kidunda Dam will provide a steady supply of water, releasing an average of 24,000 liters per second into the Ruvu River.
This consistent water flow will support the needs of households, agriculture, and industries, particularly during the dry season when water resources are typically scarce.
The dam will play a vital role in ensuring that the country’s agricultural sector remains resilient in the face of climate change and other environmental challenges.
The Kidunda Dam project is a testament to Tanzania’s commitment to sustainable development and the government’s focus on improving infrastructure to support economic growth.
It is expected to have a lasting impact on the regions it serves, providing a reliable source of water and energy for generations to come.
