A contract has been awarded for the construction of a wastewater treatment plant in Mbezi Beach, Tanzania. The contract was awarded by Dar es Salaam Water Supply and Sanitation Authority (DAWASA) to Metito.
The latter will design, construct, and run the facility which will be the first of its kind in the East African country. The project’s safe wastewater treatment is intended to reduce environmental contamination.
Expectations for the project
Contemporary engineering and technologies will be used at the 16,000 m3/day wastewater treatment plant in Dar es Salaam’s Kinondoni District. This will in turn reduce carbon emissions, improve sludge quality, and reduce operational and maintenance costs. The plant will also be constructed in almost half of the allotted area. It will maximize savings and also optimize the use of the land.

The wastewater treatment plant will be operated and maintained by Metito for three years. DAWASA staff will take part in all operational areas of the treatment plant. When the plant is fully operational, Metito will use conventional activated sludge technology, anaerobic digesters to produce biogas and a combined heat and power (CHP) generating system.
This will cut electric power use by about 40%. Metito will also employ the sludge anaerobic digestion process in the first treatment phase. As a result, the sludge will be stabilized, and its quality will be maintained.
The wastewater treatment plant in Mbezi Beach to contribute to Sustainable Development Goal 6
With the adoption of Sustainable Development Goal 6, which the UN set for 2031, Tanzania has renewed its commitment to increasing access to clean water.
The Mbezi Wastewater Treatment Plant project will support the sustained economic and industrial development of the Dar es Salaam region. It will create quality employment opportunities as well as ensure the community’s health and well-being through efficient wastewater treatment.
Karim Madwar, the managing director of Metito Africa, said that the project is a huge milestone in modernizing Dar es Salaam’s wastewater infrastructure and strengthening its resilience. According to him, it will safeguard its natural ecosystems. He added that the initiative meets all three of Metito’s basic principles: impact, sustainability, and innovation.
Karim said that they look forward to establishing the project in partnership with the Dar Es Salaam Water Supply and Sanitation Authority. He claimed that the project would serve as an example for other projects of a similar nature in the region. In partnership with the World Bank, the government of Tanzania is funding this project.
Construction is planned to commence in April 2023. The project’s commissioning is scheduled for October 2024, following the 22nd of March contract award.
