Apply direct inflows to permeable paving

There should be a way of applying the inflow that the paving receives directly (i.e. the rain that falls onto it) to produce a more accurate simulation of the rainfall. This direct rainfall isn't a lateral or point inflow, and being forced to mode...

Infiltration trench with varying depth.

It should be possible to design an infiltration trench where the long slope at the base of the trench is different to the slope at exceedance level i.e. the depth of the trench varies. Extremely useful for designing a trench that does not match fa...

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

Changes to a network do not propagate downstream

If you change a pipe diameter or gradient, it will not accommodate these changes in the downstream section of the network. For example upsizing and steepening a pipe in the middle of a run will mean the next pipeis undersized and goes uphill. It a...

Vary infiltration with depth

Cannot currently use the software for deisgn of borehole soakaways. By their very nature they wil have varying infiltration rates. Usually the infiltration is at greatest depth and no way of modelling with correct head in borehole.

Reporting of velocity through swales

If you design swales using Stormwater Controls (Swale) you will not be able to see simulated velocities through the swale. I believe you could try modelling as an open channel connection but you won't get infiltration through the sides & base.

Add check dams as a feature for swales

Add a check dam setting with height, notch weir and interval settings to simplify modelling swales on sloping sites. This avoids having to model several sections of swale in order to use the available storage.

Allow a 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...

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...
