Summary
The Dar es Salaam Water Supply and Sanitation Authority (DAWASA) recently awarded a contract to Metito to design, construct, and run a new wastewater treatment plant, in the Mbezi Beach area of the Dar es Salaam region of Tanzania. The project’s safe wastewater treatment is intended to reduce environmental contamination.
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.
