Chezy Formula option

It would be useful to have a direct input for Chezy coefficient as an alternative to mannings n as some regions need to use this as an input and report on this too - this would result in less workaround and data manipulation

Allow underdrains to have a different slope to the SuDS feature

Allow a storage structure such as dry swale, bioretention area or infiltration trench to have a different slope to the underdrain. Currently the underdrain has to follow the slope of the feature, which is not a real life representation of how they...

Incorporate the ability to create custom grate inlets. Currently InfoDrainage only allows for HEC22 defined inlet grate types to be used.

Some municipalities across New Zealand and other parts of the world require designers to use specified inlet grate types with defined inlet efficiency curves. There are two ways in which the custom inlet grate type this can be incorporated into In...

Non-circular pipes

Please add non-circular pipes to InfoDrainage, similar to those available SSA. These need the ability to connect to manholes at either end at a minimum, but the option to be culverted as well is welcomed.

Weir coefficients

Expand the allowable range of weir discharge coefficients in InfoDrainage and provide an optional depth–coefficient user defined table to improve modeling flexibility and accuracy. Weir discharge coefficients (English units) typically range betwee...

Perforated Pipe as Connection Type

I would like to be able to model a perforated pipe as a connection type rather than use an infiltration trench and short branches of pipes to connect them to other stormwater controls. These infiltration trenches are not collecting inflow from sur...

Option to remove the additional storage automatically added in geocellular systems

When designing a cellular soakaway, infodrainage automatically assumes a 1m2 plan area chamber between tank soffit and exceedance level (which would have been specified as ground level). In other structures you can specify freeboard and exceedance...

Permeable Pavement with varying depth

Please add an option to input the surface slope and formation level slope for the permeable pavements to represent the varying depth of storage below. This is one of the 3 options we use at steeper sites to provide adequate storage in permeable pa...

HEC-22 Inlet reporting

The "Export HEC-22 Result to Excel" button in the calculator only includes results. Looking at flexible reporting, the HEC-22 data is only input, so I then have to use the results data from the calculator and the input data from flexible reporting...

Liquid filled/Flooded drainage network

Liquid filled/Flooded drainage network- the system should be required to design flooded drainage network i.e. drainage pipe should be always filled with liquid for entire length up to the discharge point. Like a surcharge up to manhole cover (liqu...
