Nakivubo航道穿越人口密集的坎帕拉贫民窟、市场、工业区和湿地。它在维多利亚湖的默奇森湾排水。河道的污染程度直接影响到湖中的水生生物、河道沿着社区的健康以及水处理的成本，因为其排放点距离城市的原水取水口只有2公里。本研究调查了河道污染程度，以便在污染源处或河道内采取适当的净化措施后排入湖泊。在雨季和旱季，沿沿着在四个点取样。对样品进行pH、BOD、COD、TSS、大肠杆菌、EC、TN和O-PO 4测试。这些标准与NEMA为废水设定的标准进行了比较。结果表明，该河道污染严重。湖前的湿地有助于降低污染水平，但在排放到河道前还应进行预处理。提出了减少河道污染的建议。
Nakivubo channel traverses highly populated Kampala slums, markets, industrial areas and a wetland. It discharges its water at Murchison bay in Lake Victoria. The degree of pollution in the channel has a direct effect on the aquatic life in the lake, the health of communities along the channel, and the cost of water treatment since its discharge point is only 2kms from the raw water intake for the city. This research investigated the degree of pollution in the channel so that appropriate purification measures may be taken either at the pollution source or in the channel before discharge to the lake. Samples were taken at four points along the channel during the wet and dry seasons. The samples were tested for pH, BOD, COD, TSS, E-Coli, EC, TN, and O-PO4. These were compared with the standards set by NEMA for waste water. It was found that there is a high degree of pollution in the channel. The wetland before the lake helps to bring down pollution levels but this should be supplemented by pretreatment before discharge into the channel. Recommendations on reduction of pollution in the channel were made.
