In this study‚ macro-invertebrates community was used to establish the pollution tolerance index of four wastewater stabilization ponds at University of Eldoret in Kenya. The stabilization ponds have not been expanded since the inception of the university despite the ever rising population of students and staff. As such this study was set to evaluate the efficiency of the wastewater stabilization ponds in wastewater restoration by the use of bioindicators. Since chemical analysis is expensive and
