The General tab fields document when the smoke test took place, which crew performed the test, and the test result. The Total GPM and Remaining GPM fields, described below, are calculated by the system.

Total GPM * |
This field adds together the Remaining GPM values from the Source Details tabs of all records in the Observations grid. Flow is measured in gallons per minute (GPM). GPM is calculated using the following rational formula: Q = CIA where: Q = Flow C = Coefficient of runoff based on type of surface I = Intensity of rainfall A = Area (in acres) |
Remaining GPM * |
Represents the remaining infiltration after the structure's rehabilitation. |
* Required
* Must form a unique combination with the Alt Pipe ID.
* The Flow Rate (gpm) and % I/I Removed fields (found in the Observation records' Source Details tabs) must be populated for these calculations to be performed.
