When Basic BMPs Aren’t Enough: Upgrading for Better Stormwater Control

Identifying When Improvements Are Necessary

When rainy season hits, even well‑maintained industrial sites can find themselves facing unexpected stormwater exceedances. Many of these exceedances don’t stem from major system failures, they come from BMPs that are outdated, undersized, or simply unable to handle increased storm intensity and evolving site conditions.


If your facility has experienced benchmark exceedances, near‑misses, or recurring compliance challenges, it’s time to look beyond basic BMP maintenance and consider strategic upgrades and treatment solutions tailored for your stormwater challenges.


Below are five high‑impact BMP upgrades, including engineered treatment systems, that can reduce pollutant loads, improve system performance, and help protect your next qualifying storm sample.

1. High‑Performance Filtration Media and Upgraded Treatment Modules

One of the most impactful upgrades you can make is to enhance filtration performance. Over time, standard BMP media may lose effectiveness, especially in industrial settings with metals, oils, or organics. 


Upgrading to advanced media, such as those included in engineered treatment systems, improves:

  • TSS (Total Suspended Solids) reduction

  • Oil & Grease capture

  • Metals targeting (e.g., copper, zinc)


Solutions like StormPROOF® systems are engineered with patented Best Available Technology (BAT) and tailored filtration stages to pre‑treat, filter, and polish stormwater before discharge, especially valuable when basic BMPs alone aren’t enough for compliance.

2. Scalable, Engineered Stormwater Treatment Systems

For facilities facing persistent benchmark exceedances or complex pollutant profiles, adding an engineered treatment system can make the difference between repeated violations and reliable compliance performance. 


FROG’s StormPROOF® series offers scalable treatment solutions designed around your site’s flow rates and pollutant loads:

  • StormPROOF® 75 GPM Gravity System: A passive, energy‑efficient option ideal for moderate flows. Targets TSS, Oil & Grease, and select metals; a strong foundation for many industrial facilities.

  • Pressurized MetalPROOF®: Enhanced metals removal for sites with stricter permit requirements.

  • NitrogenPROOF®: Adds nutrient (nitrogen + phosphorus) treatment, ideal for sensitive watersheds or advanced regulatory benchmarks.


Unlike temporary or passive controls, these systems are designed, installed, and maintained as full compliance‑oriented solutions, with engineering support from FROG’s experts. 

3. Increased Storage and Flow Handling to Reduce Bypasses

Storm events are becoming more intense and unpredictable. Older BMPs that were sized for historic rainfall volumes may overflow or bypass during heavy storms, leading to untreated discharge. Upgrading detention areas, retention basins, or treatment tanks ensures your system can:

  • Accommodate peak flows

  • Slow runoff for better treatment contact time

  • Prevent untreated bypasses during qualifying events


Integrating enhanced storage with treatment systems like StormPROOF® gives regulators confidence in your site’s capacity and helps maintain compliance even under high rainfall conditions.

4. Automated Monitoring and Control Integration

Modern compliance isn’t just about hardware, it’s about data. Integrating real‑time monitoring systems with your BMP upgrades (flow sensors, turbidity monitors, automated alarms) empowers your team to:

  • Detect potential exceedances before they occur

  • Track treatment performance over time

  • Respond quickly to system stress points


This proactive approach helps reduce emergency corrective actions and strengthens documentation during inspections or SMARTS reporting.

5. Strategic BMP Layout and Integrated System Design

Sometimes the most effective upgrade isn’t a single product, it’s how everything works together.


Reassessing BMP placement, integrating upstream pretreatment with downstream engineered systems, and eliminating pollutant pathways can drastically improve overall performance. 


Consider:

  • Adding pretreatment BMPs to reduce pollutant loading

  • Positioning treatment systems at key discharge points

  • Coordinating maintenance and sampling plans to reflect site upgrades


The result? A cohesive stormwater management system that performs consistently, not just reactively.

How Advanced Treatment Fits with Everyday BMPs

Upgrades like engineered treatment systems don’t replace standard BMPs, they amplify them. While good housekeeping, inlet protection, and erosion controls are essential foundational practices, advanced systems provide consistent performance for challenging pollutants and high‑risk discharge conditions.
