1984 - 1988
The Democratic Republic of Congo, Burundi and Rwanda Republic have defined in early 1980 a common and coordinated exploitation of the water resources of some zones bordering their countries, within a development economic program.
This common aim has been realized with the construction of an hydroelectric plant , the Ruzizi 2 Power Station, and with the constitution of an international Company, SINELAC, with headquarter in Bukavu.
The principal purpose of the SINELAC Company is the improvement of the economic conditions and of the social welfare, through the exploitation of a certain power resource, utilizing the existing water patrimony.
The Ruzizi 2 dam is located in the upper part of the Ruzizi River in the area between Kivu and Tanganika Lakes, to the south of the Ruzizi I Power Station situated at a distance of about 16 km.
The principal works are the following:
- concrete dam, 40 m. long and 12 m. high
- spillway with two openings of 8 x 6 m. controlled by automatic closing gates
- intake structure with two inlets of 8 x 9 m. controlled by gates
- concrete lined headrace tunnel, 500 m. long, with circular section of 6 m. diameter
- chamber with 18 m. diameter
- steel penstock with a diameter of 5.20 m
- powerhouse, with dimensions of 44.5 m. x 21.5 m. x 29.0 m
- housing three Francis turbines of 31.3 MW each
- tailrace channel 200 m. long, 32 m wide with variable depth between 4 and 10 m
- H.T electric line with a length of 16 km
