Of course, the real world is not black and white, and it is possible to blend these categories to meet a variety of different site stormwater management objectives.  The purpose of categorizing the treatment train types into design priorities is to highlight the need to consider different objectives, while recognizing that if the design priority of the treatment train is narrowly focused, objectives other than those targeted may not be met.

The performance of a treatment train will vary based on the type of stormwater treatment practices implemented and their arrangement within the treatment train.  Various changes occur as [[Runoff volume control targets|runoff]] moves through the treatment train.  Key changes that need to be considered when [[Low impact development treatment train tool|calculating treatment train performance]] including:
