WebMar 31, 2024 · Inflow occurs as a result of storm events such as rainfall, snowfall, springs or snow melt that contribute to excessive sewer flows. Peak inflow can occur during heavy storm events when storm sewer systems are surcharged, resulting in hydraulic backups and pooling of water. WebSurcharging conditions occur when the sewer system has reached its maximum capacity and there is a consequent flow exchange between sewer and floodplain. For surcharge to occur the hydraulic head of the sewer flow must be greater than the manhole crest or, if present, the hydraulic head of the surface flow (Rubinato et al. 2024 ).
