SUSTAINABLE SURFACE WATER SOLUTIONS

NDS S5 components can be configured to meet a wide variety of residential and commercial applications.

CAPTURE

S5 offers several options to collect surface water from various sources.
CAPTURE
• Catch basins effectively function as area drains and for downspouts from roofs Catch basins
• Channel drains intercept sheet flow from paved surfaces FILTER Channel drains
• Permeable grass and gravel paver systems with underdrains collect surface water Basin and channel grates
from walkways and parking areas when used as alternatives to traditional impermeable Fabric filters in basins
solutions Grass and gravel pavers

FILTER
Prevent debris and other suspended solids in surface water from
impairing system function.
• Basin and channel grates provide a front line of mechanical filtration
• Fabric filters contribute further to the removal of fines from surface water, extending
system life
• Grass and gravel paver systems naturally filter and clean surface water while flowing
through the S5 permeable paver solutions

CONVEY
Move surface water from its sources to downstream detention,
infiltration and overflow components.
• Smooth-wall and corrugated pipe with appropriate fittings and adapters have proven CONVEY & INFILTRATE
flow characteristics to get the job done Pipes and fittings

®
• Using EZflow for conveyance will also increase system detention and infiltration, EZflow ®
Flo-Well
effectively reducing the footprint of the downstream detention area
DETAIN
S5 detention components provide efficient volume to minimize runoff and maxi-
mize infiltration.
• Flo-Well dry wells and EZflow infiltration-trench arrangements have defined volumes
®
®
for this purpose DETAIN & INFILTRATE
®
• Flo-Well has 250% more detention volume than traditional stone-filled dry wells EZflow ®
Flo-Well ®
INFILTRATE
Arrange Flo-Well dry wells and EZflow infiltration trenches in customizable
®
®
configurations and at depths suitable to existing site conditions, soil types and
groundwater elevations.
• Flo-Well has an open bottom and side knockouts to allow direct infiltration
®
• EZflow maximizes soil-contact area for effective infiltration
®
OVERFLOW
Allow for excess surface water beyond the design storm to overflow from the
system in a safe, suitable downstream location.
