Gas Station Trench Drains

Typically D400 to F900, depending on traffic intensity.

• Fueling areas and drive lanes: D400–E600 for passenger and light truck traffic.

• Delivery zones and tanker truck areas: E600–F900 heavy-duty rating.

• Pedestrian walkways: A15–B125, often integrated near store entrances.

Gas station drainage systems must resist fuel, oil, and solvent exposure as well as harsh weather conditions.

• Fiber-Reinforced Concrete (FRC) or Polymer Concrete channels for strength and impact resistance.

• HDPE chemical-resistant systems for lighter-duty or retrofit applications.

• Ductile-iron grates with anti-slip coatings for fueling zones.

• Galvanized or stainless edge rails to prevent chipping and long-term degradation.

• Epoxy or resin-coated channels for additional chemical protection.

• Large impervious forecourts generate high surface runoff during storms.

• Systems must connect to oil/water separators to prevent hydrocarbon contamination.

• Grates must maintain traction even when wet or oily.

• Drains are typically placed parallel to pump islands, canopy edges, and drive lanes for efficient capture.

• Proper slope (1–2%) ensures rapid removal of water and fuel films.

• Safety: Non-slip, ADA-compliant grates prevent slips and falls in wet fueling areas.

• Chemical resistance: Withstand continuous exposure to petroleum and detergents.

• High flow capacity: Manage stormwater while containing small fuel spills.

• Ease of maintenance: Quick access for cleaning and sediment removal.

• Environmental compliance: Must integrate with oil/water separation and containment systems.
