MANHOLE CASTING REFERENCE GUIDE
Hydraulic Efficiency The hydraulic efficiency of a grate is its rated ability to intercept storm water. Hydraulic tests prove that the Vane style grate, properly installed, will accept as much as 20% more water than any of the conventional grate styles. Cross section of vane-style grate in testing flume showing hydraulic performance at 2 cfs ...
