Warminster’s walk-on algae control covers are engineered to block sunlight and reduce biological growth in water and wastewater treatment systems.
Designed as strong, structural FRP panels, these covers support safe foot traffic while delivering long-term corrosion resistance in harsh outdoor environments.
These covers are commonly used in:
By limiting light penetration, algae formation is significantly reduced—lowering maintenance needs and improving operational efficiency.


Each cover is designed to support foot traffic with an integrated non-slip surface. Key features include:
These covers provide safe access for operators during routine inspections and maintenance.
Walk-on covers are manufactured as modular sections that can be installed over existing structures with minimal downtime. Panels can be supplied with:
Each system is designed to integrate seamlessly with new or existing plant infrastructure.


Warminster’s covers can be fabricated to meet specific basin, launder, or channel geometries. Custom options include:

All walk-on algae control covers are manufactured using materials that meet ANSI/AWWA F101 performance standards for FRP construction. Products can also be supplied to meet:
These compliance options make our covers suitable for publicly funded water treatment projects.
Warminster’s FRP algae control covers provide durable, long-term protection against sunlight exposure and biological growth.
With walkable construction, reinforced strength, and corrosion-resistant materials, these covers offer an ideal combination of safety and performance for water and wastewater facilities.
