Drainage & Containment
Design drainage and containment systems to manage stormwater, prevent flooding, and control spills.
Service Overview
At Engineering Design Services, our drainage & containment services focus on designing systems that safely manage stormwater, process runoff, and potential spill scenarios within industrial and commercial facilities. We take an engineering-driven approach to ensure fluids are properly collected, directed, treated, and contained in accordance with environmental and safety requirements.
Our team works closely with civil, structural, process, and environmental disciplines to develop integrated drainage and containment solutions that reflect site conditions, regulatory requirements, and operational needs. From conceptual site layouts to detailed grading, drainage networks, and secondary containment systems, we ensure each design is practical, compliant, and buildable.
By combining hydraulic design principles with real-world facility constraints, we deliver systems that reduce environmental risk, protect equipment, and support safe operations. Whether for new facility development or upgrades to existing sites, our solutions are designed for long-term performance and reliability.
Engineering Challenge We Solve
Poorly designed drainage and containment systems can lead to environmental incidents, operational disruptions, and regulatory non-compliance. Our approach addresses these challenges by:
Preventing Environmental Releases: Designing containment systems to manage potential spills and leaks.
Improving Stormwater Management: Controlling runoff to prevent flooding and site erosion.
Ensuring Regulatory Compliance: Aligning designs with EPA, state, and local environmental requirements.
Protecting Critical Equipment: Directing water and process fluids away from sensitive infrastructure.
Optimizing Site Grading: Designing efficient flow paths that support safe and functional site layouts.
Core Capabilities
Our team provides comprehensive drainage and containment services across all project phases:
Site Drainage Design: Development of stormwater conveyance systems, swales, and piping networks.
Secondary Containment Systems: Design of berms, dikes, and impoundment areas for spill control.
Hydraulic Calculations: Flow analysis for pipes, channels, and open drainage systems.
Grading & Site Layout Design: Optimization of site elevations for proper drainage performance.
Spill Prevention Planning: Integration of containment strategies for process and storage areas.
Retrofit & Expansion Support: Upgrades to existing drainage infrastructure for facility changes.
Advanced Tools & Technical Expertise
We apply proven engineering methods and industry standards to ensure reliable drainage and containment systems:
Industry Standards: Compliance with EPA SPCC requirements, local stormwater regulations, and applicable environmental codes.
Hydraulic Analysis Tools: Use of modeling software for flow, capacity, and system performance evaluation.
Civil Engineering Expertise: Integration of grading, paving, and structural drainage considerations.
Cross-Discipline Coordination: Collaboration with process, piping, structural, and environmental teams.
Field-Informed Design: Consideration of constructability, maintenance access, and real-world site conditions.
