Covers for Wastewater Equipment

Updated: Jun 21

In wastewater treatment, equipment covers serve crucial roles such as odor control, safety, environmental protection, and containment of hazardous substances. Common materials for these covers include Fiberglass Reinforced Plastic (FRP), stainless steel, aluminum, high-density polyethylene (HDPE), polypropylene, concrete, and polyvinyl chloride (PVC). Each material is chosen based on specific requirements and conditions.


Fiberglass Reinforced Plastic (FRP) covers are lightweight, corrosion-resistant, and durable, making them ideal for covering tanks and clarifiers to contain odors and prevent evaporation. They offer excellent chemical resistance and strength, making them suitable for chemically harsh environments.


Stainless steel covers provide high strength and resistance to corrosion, perfect for applications where durability and structural integrity are crucial. Similarly, aluminum covers are lightweight and resistant to corrosion which makes them ideal for large span covers over tanks and basins where weight is a concern.

High-density polyethylene (HDPE) and polypropylene covers are valued for their chemical resistance and flexibility. HDPE is commonly used for geomembranes and floating covers to contain odors and prevent contamination. Polypropylene offers similar benefits and is suitable for various environmental conditions.



Concrete covers are robust and durable, used for heavy-duty applications such as large tanks and basins. They are extremely durable, fire-resistant, and capable of supporting heavy loads, making them excellent for critical infrastructure in wastewater facilities. PVC covers, with good chemical resistance and flexibility, are often used as floating covers or geomembranes.


These covers control odors, enhance safety by preventing falls and chemical exposure, and protect equipment from environmental elements. They also contain hazardous substances to ensure regulatory compliance, maintain optimal conditions for efficient processing, and improve the facility's appearance by concealing equipment.
