Overview

Ohio State University researchers have developed a barrier inlet screening technology that reduces large debris accumulation and associated maintenance risks in highway stormwater systems.

The Opportunity

This technology introduces a universally compatible, externally mounted inlet screen that intercepts large debris at the inlet face without materially compromising hydraulic performance. Validated through full‑scale laboratory modeling and multi‑year field deployment, the solution enables infrastructure owners to shift from reactive subsurface cleaning to proactive surface‑level debris management with measurable operational and safety benefits.

Key Advantages

• Lifecycle Cost Reduction: Decreases reliance on heavy sewer cleaning, delivering meaningful maintenance savings.
• Improved Workforce Safety: Reduces the frequency of traffic‑adjacent, labor‑intensive maintenance activities.
• Retrofit Compatibility: Installs on standard barrier inlets without modifying existing drainage infrastructure.
• Balanced Drainage Performance: Optimized geometry retains problematic debris while maintaining water conveyance.
• Scalable Deployment: Suitable for system‑wide use across highways, bridges, and urban road networks.

Transform Your Transportation Infrastructure

Barrier inlet screening allows agencies and infrastructure partners to modernize stormwater maintenance strategies with a proven, scalable solution. By improving drainage reliability while lowering operational risk and cost exposure, this technology supports safer roadways, cleaner waterways, and more resilient transportation systems.
