Wastewater Treatment Solutions for Petrol Stations

Petrol stations face ongoing challenges in managing wastewater contaminated with oil, fuel, grease, and other hydrocarbons. Vehicle movement, fuel dispensing, washdowns, and mechanical work create the risk of spills and runoff that, if left untreated, can pollute the environment and breach water discharge regulations.

Baldwin Industrial Systems supplies complete wastewater treatment solutions tailored to the needs of service stations and forecourts. From oil-water separation to final polishing, our systems are built to manage oily runoff, support sustainable practices, and help you stay compliant with strict water authority requirements.

Complete Solutions for Fuel Station Wastewater

Petrol stations require compact, reliable systems that can handle wastewater in high-traffic areas such as wash bays, forecourts, and mechanical servicing zones. Wastewater from these areas may contain diesel, hydraulic oil, lubricating greases, coolants, detergents, degreasers, heavy metals, and sludge from vehicle washdowns.

Oil Skimmers (Belt, Tube & Floating)

Skim surface oil and fuel before they enter your primary separator. Skimmers reduce hydrocarbons early on, protecting downstream equipment and reducing maintenance.

Coalescing Plate Oil Water Separators

These compact, low-maintenance units remove free-floating oil, diesel, and fuel using plate technology and gravity. Suitable for high-traffic areas like uncovered forecourts, they meet Class 1 separator standards and support environmental compliance for service stations.

Dissolved Air Flotation (DAF) Systems

DAF systems are ideal for wash bays and mechanical servicing areas, where emulsified oils, detergents, and fine solids are common. They remove suspended solids and cleaning residues from water generated during engine servicing or pressure cleaning.

Clarifiers

Used to settle heavy solids, grit, and oily sludge from vehicle washdowns or stormwater runoff. Clarifiers reduce solids loading on your system and improve downstream performance.

pH & Dosing Systems

Dosing systems neutralise water affected by acidic or chemical-laden waste from degreasers, soaps, and fuel additives. Balancing pH ensures compliant discharge and protects your infrastructure.

Filtration & Polishing Media

Final-stage filters remove suspended solids, metals, and other fine contaminants. These systems are vital for sites looking to reuse treated water in washdown operations or landscaping.

Control Panels

Automated control panels streamline system management and provide real-time monitoring for multiple components. They help keep your treatment process efficient and consistent.

Custom Fabrication

No two sites are the same. We build modular, skid-mounted systems that fit your space, flow rate, and contaminant profile. Whether you need a targeted solution for a fuel island or a full-site wastewater setup, we’ve got you covered.

Why Proper Wastewater Management Matters

Having the right system in place is more than just ticking a compliance box. It protects the environment, supports safe site conditions, and reduces ongoing maintenance costs. Whether you’re dealing with oily wastewater from diesel fuel or sediment from wash bays, Baldwin provides tailored solutions for service stations of all sizes.

 

What are the Key Benefits?

  • Efficient Oil & Fuel Removal: Prevents hydrocarbons from entering stormwater or sewer systems.
  • Regulatory Compliance: Helps meet EPA and water authority discharge standards for forecourts and fuel handling areas.
  • Supports Water Reuse: Treated water can be reused in washdown applications or landscaping.
  • Safer Site Conditions: Reduces slip hazards and protects hardstand surfaces from oil damage.
  • Lower Maintenance Costs: Proper treatment reduces pipe blockages, pump wear, and service downtime.

 

Applications Across Your Site

Our systems are suited to multiple areas around a service station or fuel depot:

  • Undercover and uncovered fuelling areas
  • Vehicle washdown bays
  • Stormwater collection points
  • Mechanical servicing and engine cleaning zones
  • Bunded storage areas for fuel and chemicals

With Baldwin’s modular and scalable systems, you can address specific problem areas or implement a site-wide solution.

Frequently Asked Questions

The ideal system will depend on your site layout, volume of runoff, and types of contaminants. Most sites benefit from a combination of oil skimmers, coalescing plate separators, and clarifiers. For wash bays or mechanical areas, DAF systems and pH dosing units may also be required. Baldwin’s systems are designed for oily water management in high-traffic fuelling areas and heavy washdown zones.

Class 1 separators are typically required for forecourts, fuel islands, and uncovered areas exposed to fuel spills or vehicle movement. Baldwin’s coalescing plate separators meet Class 1 standards and are designed for easy installation and maintenance.

Yes, depending on your treatment system. Many Baldwin clients reuse treated water for washdowns, dust suppression, or landscaping. Including filtration and polishing media in your setup helps produce water clean enough for reuse. 

Not always, but it’s recommended in areas where degreasers or cleaning agents are used. pH control ensures your water is balanced before discharge and helps prevent damage to pipes and downstream systems. 

The maintenance needs will vary depending on your specific systems and site usage. Baldwin’s equipment is designed for easy servicing, and we offer low-maintenance options like self-cleaning separations and accessible skimmers.
