What material are strainer baskets typically made of to prevent debris from entering stormwater systems?

Strainer baskets are crucial components in stormwater systems, as they filter out debris and prevent clogs and blockages that could lead to flooding or other drainage issues. The materials chosen for making these strainer baskets play a vital role in ensuring durability, resistance to corrosion, and overall effectiveness.

Cast iron and cast aluminum are strong and durable materials that resist corrosion, making them excellent choices for outdoor applications like stormwater systems. They can withstand harsh environmental conditions and are heavy enough to resist displacement in high-flow situations. Plastic components are also common because they are lightweight, resistant to chemicals, and can be molded into complex shapes to efficiently catch debris while allowing water to flow through.

In contrast, other materials listed in the options may not provide the same durability or effectiveness. Steel, while strong, is prone to rust if not properly coated. PVC is lightweight but may not have the structural integrity required for heavy debris. Rubber and similar materials may not hold shape or strength over long periods when exposed to external conditions. The inclusion of galvanized metal, glass, or fabric in another option may also not hold up well against heavy rainfall or continuous water flow, leading to reduced performance in filtration and maintenance challenges.

Overall, the combination of strong, corrosion-resistant materials like cast
