The Ndurumu River (French: Rivière Ndurumu) is a river in Karuzi Province, Burundi. It is a left tributary of the Ruvubu River.

Course

The Ndurumu River rises in the north of Karuzi Province and flows south past Buhiga and Karuzi, then south-southwest parallel to the RN 12 highway down to the border with Gitega Province, where it joins the Ruvubu River.[1] It is one of the main tributaries of the Ruvubu.[2]

Environment

The surroundings of the Ndurumu River are a mosaic of farmland and natural vegetation.[3] The area is quite densely populated, with 239 inhabitants per square kilometer as of 2016.[4] The average annual temperature in the area is 20 °C (68 °F). The warmest month is September, when the average temperature is 23 °C (73 °F), and the coldest is April, with 18 °C (64 °F).[5] Average annual rainfall is 1,321 millimetres (52.0 in). The rainiest month is December, with an average of 215 millimetres (8.5 in) of precipitation, and the driest is July, with 1 millimetre (0.039 in) of precipitation.[6]

Power Station

The Buhiga Hydroelectric Power Station is on the Ndurumu River, near the town of Buhiga. The power station has a hydraulic head of 26 metres (85 ft) and installed power of 220 kW using an Ossberger turbine.[7] A concrete masonry gravity dam diverts water from the upper Ndurumu River into the intake and settling area. From there, it flows through a 440 metres (1,440 ft) power canal, then down a steel penstock to the turbogenerator.[8]
