Conventional infiltration & inflow (I&I) investigations are both costly and time-consuming, often requiring the installation of flow meters and two to three years of flow monitoring of the wastewater service area. To reduce the high cost and time of flow monitoring in I&I studies, a technology was developed to estimate locations of high levels of rainfall-derived infiltration & inflow (RDI&I) by analyzing historical data gathered at the wastewater treatment plant and radar rainfall data. This paper describes this unique I&I investigation method and the forecasting technology employed in estimating RDI&I volume.
