Abstract
In the particular embodiments described in the specification, a virtual sewer flow monitor detects flow rate and depth information periodically and supplies it to a scattergraph generator and a polynomial curve generator produces a polynomial curve corresponding to the scattergraph data. A filter eliminates polynomial curve portions corresponding to normal sewer flow conditions and an SSO detector responds to curve portions indicating a sewer overflow condition to generate an alarm.
