INTRODUCTION Water lilies also known as water hyacinth are aquatic plants found in countries with tropical weather. It grows and multiples fast that it accumulates and hinder the flow of water and increase the accumulation of garbage in the sewage and other bodies of water, increasing pollution and flood probability. It also cause poor water circulation which destroys fish pens and kills fish due to the decay of aquatic plants.(Ani,2011) Water lilies have caused great problem in the lakes, rivers and other water ways in the country. The accumulation of water hyacinth not only increase the pollution in the water but also increased the flooding both in rural and urban communities in great effect. The branching of problems brought about by water hyacinth introduced the idea of using it as an alternative source of energy to meet the ever growing demand in energy. The biogas production could be an option in developing countries, where it is often found, requiring investments and technological skills.
