This research was carried out to make use of water hyacinth to produce biogas which may solve the problem of water hyacinth management as well as provide a solution to energy and power shortages. Samples of water-hyacinth were identified and collected and the cow dung was obtained from an abattoir. One (1) single 120 improvised rubber cylinder can be used as an anaerobic. Three (3)  of water was added for the 30 days retention time. The cow dung was mixed with water at a ratio of 3 : 1. The slurry of cow dung and water hyacinth substrates was then fed to the for the fermentation process to begin. Experiments were carried out during the cool season and dry season (20– 40C). The gas was collected and stored in the gas bag. The volume of was measured using an EL- STER HANDEL GMBH MAINZ volumetric meter, which has a limit of detection of less than 0.0010m3. The products obtained from the anaerobic digestion of water hyacinth were the compost that is removed from the at the end of the digestion process. The study’s evaluation of production potential over a 30 days period revealed marked seasonal variations in biogas outflow.
