As stormwater compliance becomes increasingly complex and steel prices continue to rise stormwater professionals are seeking better, smarter solutions. Plastic composite inlet filters are emerging as the preferred alternative to traditional steel units. Lightweight, corrosion-resistant, and easy to maintain, they deliver long-term savings while enhancing pollution capture performance.
For municipalities, public works departments, and engineering consultants, effective stormwater waste management is critical. Trash capture inlet filters prevent debris from clogging drainage systems and polluting waterways. While stainless steel has long been the standard, engineered plastics are redefining expectations offering superior performance, sustainability, and cost-effectiveness, especially as steel tariffs drive up project costs.
At EnviroPod™, with more than 65,000 installations worldwide, we understand the unique challenges faced by municipalities. Coastal environments expose stainless steel filters to salt-laden air and chloride ions, causing rapid corrosion. De-icing salts and industrial runoff further accelerate degradation, leading to costly repairs and replacements.
To combat this, stainless steel filters often require a costly upgrade to 316 stainless steel with 2% molybdenum. This not only increases the initial expense but also makes field repairs and modifications incredibly difficult and expensive, impacting already strained public works budgets.
Unlike steel, plastic composites such as polypropylene (PP) and polyethylene (PE) are chemically inert, resisting corrosion from salt, acids, and chemicals found in stormwater. Independent studies confirm that even concentrated sulfuric acid has minimal impact on these materials.
This inherent resistance means:
• Longer lifespan and lower maintenance
• Reduced risk of corrosion-related failures
• Significant cost savings over time
For municipalities, that means fewer replacements and more funds directed toward other critical infrastructure.
Plastic’s moldability enables customised designs that suit any project. Features like locking mechanisms, modular filtration components, and fiber-reinforced polymers (FRPs) combine the strength of steel with the flexibility and lightness of plastic.
For consultants, this flexibility simplifies retrofitting existing infrastructure, reducing installation time and labour costs. Unlike steel, plastic components don’t suffer from galvanic corrosion, allowing for multi-material integration, each part optimised for its specific function.
Plastic filters are significantly lighter than steel, making them easier and cheaper to transport and install. This translates into lower labour costs and faster deployment.
Maintenance is simpler too no specialised equipment required. Public works teams can clean and maintain plastic trash capture devices by hand, improving response times and reducing the risk of overflows or flooding during storm events.
Modern engineered plastics used in stormwater systems are increasingly sustainable. Compared to steel manufacturing, plastic production consumes less energy and generates a smaller carbon footprint. Many components are recyclable or made from recycled content, aligning with municipal sustainability goals and regulatory compliance requirements.
Choosing plastic supports a circular economy and demonstrates a commitment to environmental stewardship, protecting waterways, reducing waste, and promoting long-term resilience.
Don't let the lightweight nature fool you. Engineered plastics are incredibly strong and durable. They are designed for heavy debris loads, water pressure, and harsh urban environmental conditions. Unlike steel, which can dent and deform, plastic maintains its integrity, ensuring long-term performance and reliability.
Fiber reinforcements in the plastic further enhance the strength, making it comparable to steel in demanding applications. Our engineered plastics are rigorously tested to ensure long-term performance in demanding conditions, giving municipalities and consultants confidence in the solution. Furthermore, with a smart modular design, components can easily and cheaply be replaced if required, as opposed to replacing a complete product.

Plastic composite filters deliver measurable economic benefits at every stage. From transport to installation and maintenance. As steel tariffs and material costs rise, plastic filters provide a high return on investment (ROI) and long-term reliability.
Plastic trash capture devices offer a compelling combination of performance, sustainability, and cost-effectiveness. With their superior corrosion resistance, design flexibility, ease of maintenance, and environmental benefits, they represent a smarter, more responsible approach to stormwater management. And in today's economic climate, the cost savings offered by plastic make it an even more attractive option for municipalities and a valuable solution for consultants to offer their clients. It's time to embrace the future of trash capture and make the switch to plastic.
