Open Bed S<strong>and</strong> Filter<br />
The WQCV basin may be oversized to contain the<br />
EURV, in which case design the orifice outlet to drain the<br />
EURV in 72 hours <strong>and</strong> control the 100-year volume as<br />
described in the Manual.<br />
Inlet Works<br />
Provide an energy dissipating outlet for all inlet<br />
points into the s<strong>and</strong> filter. Use an impact basin for pipes<br />
<strong>and</strong> a baffle chute or grouted sloping boulder drop if a<br />
channel or swale is used. Install a Type VL or L riprap<br />
basin at the inlet over a geotextile fabric that is wrapped<br />
up on the sides to the top of the s<strong>and</strong> layer. Fill all rock<br />
voids with filter s<strong>and</strong>.
