Each Stormwater Control has an associated sizing calculator that allows the user to either:

(a) specify a new volume for the Stormwater Control whilst varying a chosen dimension, e.g. Depth, Width, Length etc.

(b) specify a scale factor to modify the existing volume of the Stormwater Control, again whilst varying a chosen dimension

(c) in the case of a Tank or Pond to specify a particular side slope, either from its top downwards or base upwards
