Most jurisdictions do not allow you to go more than 400-600 feet between manholes. Most hydraulic books and schooling uses ft/100ft for that reason. Please add the option of having ft/100ft for slope of conduits as a reportable units.

Please develop documentation for the C# API for SewerGEMS similar to what already exists for WaterGEMS.

The message prompting before every simulation computing is ambiguous - is it necessary to regenerate grid each time I want to compute model? Probably not if the grid wasn't changed.

It would be nice if the Grid browser could be docked on the side of the window.

would be nice to add the duration depth frequency data as presented in atlas 14

The majority of new development sewage pumping stations include submersible pumps. I would like if there was a better way to input vertical pipe data, as well as be able to more accurately display the vertical pipes on the profile view.

I advise to include the possibility for SCS dimensionless curves for 6 and 12 hours events instead of only 24 hours as per current OpenFlows products.

For 2d calculation, the option for hot start should be added, especially that this kind of calculations takes long time.

Tool to display custom turbine curves / characteristics in hill chart form or otherwise, to allow checking input data for correctness, accuracy, sense. To assist in diagnosing issues when using custom turbine curves. To allow comparing different t...

ARI has a valve that they call a 'dynamic combination air valve'. See here for details: https://www.arivalves.com/products/water-supply/item/d-070-dynamic-combination-air-valve This is similar to HAMMER's slow closing air valve, but only starts to...
