Product Description
De Water Bags are designed to control and filter sit and
sediment-laden water during de-watering activities. De
Water Bags are constructed of non-woven geotextile mate-
rial that filters soil particles greater than 150 microns (.150
mm), while allowing discharge water to pass through the
bag. Each bag has an adjustable spout to accommodate a
discharge hose of up to six inches (6”). The amount of dis-
charge water a bag can effectively filter depends upon
such factors as the flow rate of the pump, the amount and
type of sediment, degree of the slope, and the permeabili-
ty of the underlying surface. De Water Bags are available
in 10 standard sizes, custom sizes available.
Installations Guidelines
• Lifting straps (not included) can be placed under the filter
bag to facilitate easy removal.
• Unfold filter bag on a stabilized area over either a bed
of straw evenly distributed at a rate of one (1) bale per
30 square feet, or on an aggregate pad constructed of
#57 stone at a minimum depth of three inches (3”). The
filter bag should not be placed on bare soil.
• Insert discharge pump hose into the filter bag spout a min-
imum of six inches (6”) and tightly secure the hose with
tie wire or a pipe clamp to prevent water from flowing
out of spout without being filtered.
Maintenance
Monitor and evaluate entire pumping and filtering
operation to assure that the bag continues to function
properly. As the bag collects sediment particles the flow
from the bag will be reduced. Replace the filter bag when
it is 1/2 full of sediment or when the sediment has reduced
the discharged flow rate to an impractical rate. Overfilling,
extreme pumping rates, and hight sediment concentration
can cause the filter bag to burst.
