Troughs
Fiberglass reinforced polyester troughs, manufactured by Warminster Fiberglass, are
designed for use in water and wastewater treatment plants. They are fabricated to
ANSI/AWWA F101-96 Standards and are UL Classified for drinking water system components.
Typically, they are used either as wash troughs in the backwashing of gravity filters,
or as collection troughs (launders) in structures such as clarifiers and settling basins.
Warminster Fiberglass troughs are available in a wide variety of widths and depths,
with round or flat bottoms. They can be molded in a circular configuration to mount
against a round tank wall or inboard from the tank wall to double the weir footage.
