The goal of this study was to identify environmental, economic, and other non-quantifiable impacts that result from reducing I/I in small collection systems in the great plains region. Results of the study are based on original construction plans and specifications, operational energy bills, discharge monitoring reports, budgetary documentation, and some anecdotal observations. Of the 10 case studies, seven employ mechanical wastewater treatment technologies and three utilize waste stabilization ponds. Five of the mechanical plants exhibit notable positive impacts associated with reduced I/I, while two mechanical plants show more marginal positive impacts. The lagoons studied show impacts smaller in magnitude than those of mechanical plants and are highly dependent of site-specific factors.
