Warminster’s FRP collection troughs are engineered for long-term service in municipal and industrial water treatment systems.
Built from reinforced fiberglass laminates, these troughs offer exceptional corrosion resistance and structural stability in continuous wet environments.
Collection troughs play an essential role in directing clarified water, wash water, and process flow. Our FRP troughs are commonly used in:
Their lightweight construction and high durability make FRP a more reliable alternative to concrete, steel, or aluminum troughs—especially in corrosive conditions.
Warminster manufactures both flat-bottom and round-bottom collection troughs to meet project-specific hydraulic and structural requirements.
Ideal for standard flow distribution with uniform wall thickness and integral stiffeners.
Designed for improved flow characteristics and easier cleaning, with molded curvature for added rigidity.
Each collection trough includes:
This construction ensures long-term resistance to cracking, corrosion, impact, and chemical exposure.
Our collection troughs can be built to match nearly any dimensional or hydraulic requirement. Available options include:
Warminster can manufacture directly from engineering drawings—or assist with dimensional planning if only basic information is available.
Collection troughs are manufactured using materials that meet ANSI/AWWA F101 standards for FRP construction. For potable water applications, they can also be produced with NSF-certified materials.
We also support:
This ensures that our components meet the needs of municipal specifications and funding guidelines.
With decades of use across water and wastewater treatment facilities, Warminster’s FRP collection troughs provide a dependable, low-maintenance solution for clarifier and filtration systems.
Their strength, corrosion resistance, and flexibility make them an excellent choice for both new plant construction and retrofit applications.
