A note from the BAI Group team:
Modern infrastructure isn’t just built; it is continuously measured, tested, and adjusted over time. We’ve created a five-part series that explores the systems most people never see but rely on every day: stormwater treatment, landfill reconstruction, environmental compliance, and long-term capacity planning.
Each post draws on real engineering work at BAI Group to show how decisions are made in the field and why they matter. For students, early-career engineers, and clients alike, this series connects engineering fundamentals to real-world performance and responsibility.
At the end of each, we include Questions to Consider, Applied AI Tips, and Sample Prompts and Responsible Use to help organizations strengthen their systems responsibly. We hope you find this series insightful. Check back each month for a new angle to explore.
Stormwater management is one of the first and most critical responsibilities in civil and environmental engineering. Every site must control not only how water flows, but what it carries off-site.
This post draws on real engineering work at BAI, where stormwater treatment became a complex problem driven more by particle behavior than by flow volume.
It starts with water because everything depends on where it goes and what it carries.
Before any infrastructure can perform as intended, stormwater must be controlled. But at this site, the issue was not flow rate or volume. It was what remained suspended in the water after treatment.
Stormwater leaving the landfill carried fine colloidal clays, particles small enough to remain suspended even after passing through multiple traditional and non-traditional passive treatment systems. Despite repeated design adjustments, turbidity remained above discharge requirements.
This is not a typical sediment problem. These particles do not readily settle under gravity. Their behavior is influenced by particle size, surface charge, and flow energy, which means detention alone is often insufficient.
“The goal isn’t to fight the site; it’s to understand how water wants to move and design a system that works with it.” — Jim Echard, P.E., President, BAI Group
BAI shifted the design approach from storage and retention time to hydraulics.
Instead of relying on a single basin, the team recommended a regenerative step-pool system — a series of controlled drops, pools, and filtration zones — combined with wetland species. Each step reduces flow velocity and increases interaction among water, media, and plants, creating repeated opportunities for particle separation.
This staged approach distributes treatment across multiple points rather than relying on one location to achieve compliance.
The result was measurable. Turbidity levels were reduced to near-background levels, achieving discharge compliance without chemical treatment.
This type of challenge reflects the kind of long-term, site-specific problem-solving that BAI provides, where standard solutions are not enough. Stormwater problems are rarely about volume. They are about particle behavior.
Why it matters is straightforward. Discharge violations can lead to regulatory action, environmental impact on receiving waters, and increased operational costs.
Questions to Consider
• What are the actual particle characteristics driving turbidity at your site?
• Are your systems designed for detention or for energy dissipation and contact time?
• Where have traditional approaches failed, and what does that indicate about site conditions?
Applied AI Tips
AI tools can assist in organizing and interpreting stormwater data, but they are still in the early stages of application within environmental engineering. Outputs should support, not replace, engineering analysis and must always be verified.
• Identify trends in turbidity relative to rainfall and operations
• Draft monitoring summaries for internal and regulatory use
Sample Prompts & Responsible Use
Example Prompts
“Analyze this turbidity dataset and identify trends following major storm events.”
“Draft a stormwater compliance summary based on these monitoring results.”
Documents to Use
• Stormwater sampling data
• Laboratory reports
• Inspection logs
Responsible Use
• Confirm permission before using AI with project data
• Use tools that do not retain or train on your inputs
• Avoid uploading sensitive environmental data without approval
• AI is still evolving, always verify and validate outputs
