To understand the diversity of phytoplanktons in waste stabilization pond effluents the hitherto study is undertaken. Species diversity indices of Shannon–Wiener and Simpson were applied to phytoplanktons. The diversity indices are of mathematical function to explain the abundance of each species. The total numbers of algae identified were 71 species belonging to Cyanophyceae, Chlorophyceae, Euglenophyceae, Bacillariophyceace and Desmidaceae. Chlorella and Scenedesmus were the dominant forms among the algal genera throughout the study period. Phytoplanktons play a vital role in improving the water quality of wastewater in waste stabilization ponds. Diversity indices provide important information about rarity and commonness of species in a community. The diversity indices of all the species explained the water was moderately polluted with less diversity level and highest possible equal number of different species of phytoplanktons. Greater impact of pollution leads to the lesser diversity of phytoplanktons.
