Inflow and infiltration (I/I) within a sanitary sewer system are normally tracked by comparing dry weather flow rates to wet weather conditions. This approach requires that both dry weather and wet weather data be collected; the difference between these data identifies areas with I/I. While this approach works well, there is one uncontrollable factor that derails the practice – no wet weather.

Drought conditions obviously hamper efforts to target I/I in sanitary sewers. Rain events are hard to come by, and a reduction in sewer flow is observed due to both a decrease in ground water levels and water conservation measures. However, drought conditions can be leveraged by looking for flow that isn't there. Sewer flows that show decreasing trends during a drought provide a means to identify areas that are vulnerable to base infiltration offering additional unexpected clues to continue the hunt for inflow and infiltration – even in a drought.
