1 Maximum design flow rates are theoretical minimums using Mannings n=0.012 with 30mm freeboard below grating.
2 Zero Fall Sections are used where surface slope exists or to extend drain length.
3 Channel sections can be custom designed (% fall, length) to suit site specific conditiions.
(additional lead time is required)
4 Overall drain length can be cut to size to less that 0.5m multiples if required, extra charges will apply.
