Hydro’s Treatment Train’ SuDS Tool

The free-to-use Treatment Selection Tool, available at www.hydro-int.com/stormtrain/tool , has been developed by Hydro International in response to tougher environmental and planning requirements for SuDS that remove silts, sediments, oils and pollutants from surface water runoff.

Hydro's Treatment Train' SuDS Tool

To achieve required water quality on a new development, car park or highway, multiple stages of SuDS features may need to be used in sequence to achieve a so-called ‘treatment train’.

This approach is already established as the preferred method in Scotland and proposed new National SuDS Standards for England and Wales are expected to follow a similar pattern when they become law in April 2014.

With the Treatment Selection Tool, users can specify the catchment type and receiving water body and then investigate ‘what if’ scenarios to build example treatment trains. The Tool helps users understand the pros and cons of choosing different SuDS features.

The Tool calculates the consequent pollutant removal achieved, as well as working out capital and whole-life cost implications.
