Definition:
The Heavyweight DuraWattle'" is a temporary, flexible sediment control barrier. Most commonly used for perimeter
sediment control on construction sites, the DuraWattle'" is lightweight and is built to be driven over. The BMP is
installed by digging a trench behind the sidewalk, pinning the DuraWattle' tail into the trench, and bah illiing. The barrier
is reusable over multiple job sites.
Purpose:
Sediment control barriers filter water runoff from a site and prevent sediment from escaping. In order to keep
construction site in compliance, water cannot carry sediment off site or into nearby drains. The DuraWattle solves that
problem and prevents storrnwater pollution. Effective at entrances and in high traffic, the. DuraWiattle'u rebounds after
being driven over. The BMP is also durable and reusable over many job sites.
Applications:
The Heavyweight Durawattle"' can be installed on curbs, soil, and hard surfaces. It is recommended to install around
the entire perimeter of a project. Install with the tail section upstream, so water flows the proper direction through the
barrier. 9
Specifications:
• The outer mono -filament filter fabric has a flow rate of 110gpni/ft2
• ASTM D 7351 tests showed 96.6% sediment retention and 58% turbidity reduction.
• Sections of the DuraWattle7" are 12' long and connect together using an interlocking sleeve to create_,:
continuous barrier with no weak points.

POLYACRYLAMIDES (PANS) AND FLOCCULANTS
1, Select flocculants that are appropriate for the soils being exposed during
construction, selecting from the NC DWR List of Approved PAMS/Flocculants.
2. Apply flocculants at or before the inlets to Erosion and Sediment Control Measures.
3. Apply flocculants at the concentrations specified in the NC DWR List of Approved
PAMS/Flocculants and in accordance with the manufacturer's instructions.
4. Provide ponding area for containment of treated Stormwater before discharging
offsite.
5. Store flocculants in leak -proof containers that are kept under storm -resistant cover
or surrounded by secondary containment structures.

MAINTENANCE Concrete washouts should be inspected daily and after heavy rains'. Damages should
be repaired promptly. If filled to over 75 % capacity with rain water it should be vacuumed or allowed
to evaporate to avoid overflows. Before heavy rains the containers liquid level should be lowered or
the container covered to avoid an over flow during rain. When solids have hardened they should be
removed and recycled.
