Steps to Resolve Even if the overall model continuity error is good, you can still see a large diviation value if the pump related to the wet well is cycling very quickly. If the elevation difference between the on and off elevations for the pump is small, this can make it difficult to get valid results for diviation percentage, particularly if there is a lot of flow from the pump. Some adjustment to the calculation options, including the time step, may help with the overall results. However, the best option may be to verify the pump data is correct, including the pump definition and the on and off elevations.
