Basins and channel grates provide a front line of debris filtration; adding
fabric filters contributes further removal of fines from surface water, extending Outlet
system life.

CONVEYANCE Channel drain with grate
Smooth-wall and corrugated pipe with compatible fittings and adapters convey
surface water from the point of capture to the detention and infiltration area. Select
pipe type and set pipe slope to handle the anticipated runoff volumes based on
established pipe-flow characteristics. Using EZflow for conveyance may reduce the
footprint of downstream detention and infiltration areas.

DETENTION & INFILTRATION Flo-Well ®

• Flo-Well manufactured dry wells provide 189.25 liters of detention volume. Each
unit has multiple connection points including sidewall and top-cover knock outs to
receive 7.62 cm to 20.32 cm pipes. Flo-Wells are stackable and can be arranged
in multiple configurations.

• EZflow engineered French drains are 3 m bundles of Poly-Rock aggregate with
®
or without corrugated drain pipe. Bundles are available in 17.78 cm, 25.4 cm
and 38.1 cm diameters, with or without 7.62 cm, 10.16 cm or 15.24 cm pipe, EZflow French drain
®
respectively. A standard infiltration trench consists of a 3 m bundle with 10.16 cm
pipe atop two 38.1 cm aggregate-only bundles, providing over 378.54 liters of
detention volume.
