Heavy Industrial
WASTEWATER ENGINEERING SERVICES for HEAVY INDUSTRIAL MARKETS
Heavy industry environmental compliance for steel mills, manufacturing plants and industrial facilities across the United States.
When an industrial facility faces a permit deadline, a notice of violation or a capacity constraint, there’s no time for a generic response. McFadden Engineering is an industrial wastewater engineering consultant providing manufacturing plant water treatment, industrial stormwater permitting and plant environmental compliance engineering solutions for heavy industrial facilities. As industrial water and wastewater engineers with decades of hands-on experience inside steel mills, pipeline construction projects and manufacturing plants, we understand that compliance work is rarely theoretical: it’s urgent and it’s tied directly to a plant’s ability to keep operating.

QUESTIONS CLIENTS SHOULD CONSIDER
If any of these sound familiar, that’s exactly the kind of problem our engineering approach is built to solve.
HEAVY INDUSTRIAL APPLICATIONS and PROCESS SOLUTIONS
Steel Mill Process and Cooling Water Treatment
Steel mill operations generate high-volume cooling water blowdown, quench water and mill scale wastewater carrying heavy metals, oil and suspended solids. McFadden engineers treatment systems sized to the mill’s production flow and discharge permit, whether the path is direct discharge, reuse in the mill’s own process or discharge to a municipal system under a significant industrial user agreement.
Landfill Leachate and Condensate Treatment
Landfill leachate and gas-condensate wastewater are high-strength and variable, making these streams difficult to treat using conventional methods. McFadden’s OxyShark® system is engineered in combination with anaerobic pretreatment to reduce high-strength landfill wastewater well below target discharge limits, with removal efficiency exceeding 98% in combined anaerobic/OxyShark configurations.
Pulp and Paper Processing Wastewater
Pulp and paper processing generates high-volume, high-organic-load wastewater. McFadden Engineering consults for clients in the pulp and paper sector, designing treatment systems scaled to a facility’s specific processing wastewater characteristics.
General Industrial Manufacturing Wastewater
Beyond steel and paper, McFadden Engineering treats process wastewater for a range of manufacturing operations, analyzing each facility’s specific waste stream rather than applying a standard industrial design.
- Process wastewater characterization by facility and industry
- Compliance-driven treatment system design tied to permit limits
- Pretreatment evaluation for facilities discharging to a municipal system
Oil and Gas Environmental Compliance and Permitting
McFadden Engineering supports oil and gas sector clients with environmental permitting and compliance work, including pipeline construction projects subject to federal and state environmental regulations.

McFadden has an ongoing partnership with AM Calvert, an industry-leading steel fabricator near Mobile, Alabama, supporting compliance monitoring, stormwater monitoring, spill plan inspection services and implementation of best management practices (BMPs). Beyond compliance work, the McFadden team also upgraded AM Calvert’s sample collection systems, integrating auto-sampling equipment at multiple locations within the facility.
Pipeline construction projects are subject to strict environmental regulation, and McFadden’s team provided environmental permitting and BMP support during Phase 1 of a 16-inch natural gas transmission pipeline construction project in Northwest Georgia, with continued compliance work planned as Phases 2 and 3 begin. The project was supported in part by Pipeline Hazardous Material Safety Administration (PHMSA) grants issued through the U.S. Department of Transportation.

MCFADDEN ENGINEERING
ONE PARTNER for PLANT WATER, WASTEWATER and COMPLIANCE
Industrial facilities often juggle multiple vendors for treatment system design, environmental permitting and day-to-day compliance monitoring. McFadden Engineering brings all these together: industrial wastewater engineering and plant environmental compliance engineering, all of from a single engineering partner who already understands the facility’s process and permit history.
One point of contact for treatment design, permitting and ongoing compliance monitoring
Faster response when a compliance issue is urgent
Scalable support, from a single spill plan inspection to full-time compliance monitoring
How Can McFadden Help Your Facility?
We offer industrial wastewater engineering consulting to design, permit and support the compliance and treatment systems your facility depends on, whether the need is urgent or long-term.
Frequently Asked Questions
McFadden Engineering regularly supports clients facing urgent compliance deadlines, including notices of violation and new discharge limits. Contact the McFadden team and we’ll assess the situation and determine next steps as quickly as possible.
Both. McFadden Engineering supports clients with ongoing compliance monitoring, stormwater monitoring and spill plan inspections, as well as one-time projects such as treatment system design or environmental permitting for a specific capital project.
Yes. Many of our industrial clients rely on McFadden Engineering as an extension of their team for environmental compliance, monitoring and reporting, so a facility doesn’t need in-house environmental staff to maintain compliance.
