A new national assessment forecasts that the United States will need to invest $3.4 trillion in water, wastewater, and stormwater infrastructure by 2045 to maintain service reliability, public health, and environmental performance.
This figure is not just a financial projection; it’s a technical call to action.
As states and utilities prepare for unprecedented capital spending across both new construction and system rehabilitation, the question isn’t if we will upgrade our treatment systems, but how we will upgrade them.
At Pinnacle Ozone Solutions, we believe that ozone-based oxidation and the advanced engineering that enables it must be a cornerstone of that reinvestment. Here’s why.
The Challenge: 3.4 Trillion Dollars, 3 Sectors, and 3 Major Gaps
-
-
Drinking Water
-
- Aging treatment plants with outdated disinfection and chemical dosing systems
- Rising public concern over emerging contaminants and distribution system safety
- Increased pressure to minimize chemical residuals, DBPs, and taste/odor complaints
-
-
-
Wastewater
-
- Nutrient removal and effluent polishing requirements (TN, TP, TOC)
- Need for reuse-ready treatment (IPR, DPR) in water-stressed regions
- Tightening discharge permits for organics, trace contaminants, and pathogens
-
-
-
Stormwater
-
- Greater use of stormwater capture for recharge or reuse
- First-flush treatment requirements for metals, organics, and microbial load
- Highly variable flows requiring fast-start, low-footprint systems

Why Ozone Must Be Part of the Solution
Ozone is not a one-dimensional tool. It is a versatile oxidant that can simultaneously address multiple challenges within a compact, modular footprint:
| Treatment Need | Ozone’s Role |
|---|---|
| Pathogen inactivation | Achieves required CT for viruses, bacteria, protozoa |
| DBP precursor control | Breaks down NOM, reducing THM/HAA formation |
| Iron, manganese, and H2S removal | Oxidizes metals and sulfides efficiently |
| Taste, odor, and color control | Oxidizes geosmin, MIB, tannins, humics |
| Micropollutant / pharmaceutical removal | Enables AOP when paired with peroxide or UV |
| Cooling, reuse, and sidestream oxidation | Controls biofilm, scale, and BOD in industrial systems |
Modular Ozone Generators with Scalable Output
Ozone systems need to scale from 0.5 MGD rural plants to >100 MGD municipal or industrial systems. Pinnacle’s QuadBlock® architecture allows operators and engineers to:
- Right-size ozone output for demand
- Add capacity modularly as flow increases
- Ensure redundancy and serviceability during operation
High-Efficiency Gas Transfer Under Variable Conditions
As climate volatility increases, water quality parameters will shift rapidly:
- Temperature affects ozone solubility and decay
- pH and TOC influence reaction pathways
- Turbidity impacts contact time and mixing
Pinnacle systems are engineered with pressurized injection reactors, delivering >95% ozone transfer efficiency, even under shifting hydraulic or chemical loads.
Automation, Monitoring, and Control Integration
New infrastructure must be operator-friendly and automation-ready:
- Real-time ORP, ozone residual, and UVT monitoring
- Adaptive ozone dose control
- SCADA/PLC integration with redundancy alarms
- Safety interlocks to protect against over-ozonation or gas leaks
Pinnacle’s control systems allow utilities to fine-tune treatment in response to real-time water quality, minimizing energy use and maximizing oxidation performance.
Pre-Engineered Skids and Retrofit Compatibility
As part of the $3.4 trillion spend, many upgrades will occur in existing plants, not greenfield sites. That demands:
- Pre-packaged ozone systems with compact footprints
- Retrofit-friendly contactor designs
- Short commissioning timeframes
- Compatibility with existing filtration, GAC, or UV assets
Conclusion: A National Investment Requires Proven, Flexible Technology
The $3.4 trillion water infrastructure investment forecast is both staggering and necessary. But spending alone doesn’t solve problems; we need to invest wisely.
That means building oxidation systems that are:
- Technically effective across a wide spectrum of contaminants
- Operationally efficient and controllable
- Modular and scalable for future needs
- Safe, chemical-minimized, and compliant with evolving standards
At Pinnacle Ozone Solutions, we’re not just delivering ozone, we’re delivering oxidation systems built for the real-world complexity of 21st-century water treatment.
As funding rolls out, we stand ready to support engineers, utilities, and integrators designing the next generation of resilient, reliable, and responsible infrastructure.
