| dc.description.abstract | The information about the impact of drainage channels on wastewater treatment by wetlands is very important in achieving the sustainable development goal number six and the proper management of wetlands. The aim of the study was to assess the impact of Lubigi drainage channel on water treatment service by Lubigi wetland. The study was carried out in a period of about three months (June to August). The objectives of the study were to: (1) map the existing wastewater inflows into the upstream section of Lubigi wetland, (2) evaluate the spatial variation of physiochemical water quality characteristics along the drained and undrained section of the wetland, and (3) evaluate the efficiency in wastewater treatment in the drained and undrained section of Lubigi wetland. The GPS coordinates for mapping wastewater inflows in the upstream section of Lubigi wetland were captured using GPS essentials application. Four samples were collected (two along the drained and two along the undrained section) per sampling visit and three sampling visits were made making up a total of twelve samples. Samples were analyzed with in five hours after collection were the concentration of pH, EC, TSS, BOD and turbidity was analyzed. The data was analyzed using ArcGIS software, SPSS, ANOVA and excel. The study revealed that most of the inflows in the upstream section of Lubigi wetland were concentrated around Bwaise basing on the map that was produced, there was a spatial variation in the physiochemical water quality characteristics for parameters like pH, EC, TSS, and BOD except for turbidity basing on the ANOVA analysis, the results also indicated that the undrained section had a higher wastewater treatment efficiency for parameters like EC, TSS, Turbidity and BOD compared to the drained channel while the drained section had a slightly higher efficiency in the treatment of pH. It was concluded that there was spatial variation in the majority of the physiochemical water quality characteristics along the drained and undrained section of the wetland and a higher wastewater treatment efficiency in the undrained section compared to the drained section of the wetland. It was recommended that the government should consider integration of sedimentation basins along the drainage channel in order to ensure sedimentation of TSS along the drainage channel and to control siltation of the wetland and it should reduce channelization in the wetland section to ensure proper interaction of wetland plants with the wastewater for increased wastewater treatment. | en_US |
