Water supply and sanitation in Rwanda is characterized by a clear government policy and significant donor support. In response to poor sustainability of rural water systems and poor service quality, in 2002 local government in the Northern Byumba Province contracted out service provision to the local private sector in a form of public–private partnership.
Measurements of precipitation and evaporation at the Nyabisindu station show that the Mwogo river basin produces an average annual water flow of 252 millimetres (9.9 in). [8] In parts of the river valley the hills have been cleared of trees, causing erosion and silting problems. Efforts are being made to replant trees. [9]
The western third of Rwanda is mainly covered by a mountain range to the east of the Albertine Rift. Rivers drain the west side of this range into the Congo River basin via the Ruzizi River, ultimately discharging into the Atlantic Ocean. The main rivers in Rwanda that supply the Congo River basin are the Sebeya, Koko, Ruhwa, Rubyiro and Ruzizi ...
The water treatment and distribution facility is located in the lakeside community of Karenge, Rwamagana District, in the Eastern Province of Rwanda, on the shores of Lake Mugesera, approximately 50 kilometres (31 mi), by road, southeast of the city of Kigali, the national capital.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin. It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
Communal tap (standpost) for drinking water in Soweto, Johannesburg, South Africa. May 2005. Groundwater plays a key role in sustaining water supplies and livelihoods in sub-Saharan Africa especially due to its widespread availability, generally high quality, and intrinsic ability to buffer episodes of drought and increasing climate variability.
Forests absorb and then gradually release water. The effect of upstream forest clearance and siltation has been to cause the river to flood over its banks onto fields and roads during the rainy seasons, and for insufficient water to flow during the dry seasons. [8]
