VicInAqua partners organised Study Visits of outstanding and novel RAS (Recirculating Aquaculture Systems) and wastewater treatment plants in Kenya, Tanzania and Uganda. They addressed more specifically aquaculture operators, researchers and further stakeholders in Kenya, Tanzania and Uganda to boost community building and best-practice sharing in the fields.
Thika, Kenya (21 May 2019)
Partner JKUAT (Jomo Kenyatta University of Agriculture and Technology) organised a Study Visit to the Thika Water and Waste Water Treatment Company (THIWASCO) in May 2019. The plant has 11,000 active connections to the sewerage system. It was constructed in the 1970s and operated under the Thika Municipal Council until 2009. In September 2009, the department started working as a company under the Athi Water Services Board (AWSB). Its core mandate is the provision of clean water, wastewater disposal and maintenance of developed water and sanitation infrastructure in Thika sub-county. The design of the plant takes advantage of gravity with regards to the flow of water and combines series and parallel layout of twenty biological oxidation ponds. The incoming water passes through an inlet section and is then directed to a number of oxidation ponds. Various interconnected lagoons receive the effluent and take it through the natural process before it is discharged into Komu stream. A modern wastewater treatment plant is currently under construction.
Musoma, Tanzania (7 December 2018)
Partner STIPRO (Science, Technology and Innovation Policy Research Organisation, Tanzania) organised a Study Visit of a wastewater treatment plant of MUWASA (Musoma Urban Water Supply and Sanitation Authority). MUWASA was established with the objective of supplying water and implement the removal of wastewater in the Musoma Municipality in a sustainable manner.
The visit was conducted in the frame of a VicInAqua Round Table on technologies for wastewater treatment helping to improve environmental impact in Tanzania. More information about our Round Tables here.
Entebbe, Uganda (20 November 2018)
Partner NARO (National Agricultural Research Organization, Uganda) organised two Study Visits of a MBR site in a fish processing plant in Ntinda, Kampala, followed by a RAS - recirculating aquaculture system - site for live fish marketing in Naguru, Kampala.
