Gas Station & Fueling Area Drainage
Applications · Commercial & Municipal
A fueling forecourt has to capture runoff before it leaves the site, survive tanker and delivery traffic all day, and never present a loose grate to a customer's ankle. That combination — containment, load, and lock-down — is what the trench drain spec has to solve.
The forecourt problem
Fueling pads shed a mix no owner wants leaving the property: rainwater carrying fuel sheen, drips from nozzles and tanker connections, and wash-down water. Site and environmental requirements generally mean forecourt runoff is intercepted at the pad and routed through an oil/water separator before discharge — the trench drain run around the fuel island and across the canopy drip line is how the water gets captured in the first place. Confirm the routing and separator requirements with your local authority; the drainage hardware below is the capture side of that system.
The mechanical duty is just as demanding. A forecourt is not average parking-lot traffic: fuel tankers arrive weekly or daily, turn tightly, and brake over the same runs, and the constant torque of vehicles maneuvering at the pumps works on grates all day. Grates that loosen become trip hazards a step away from the pump; grates that crack shut down an island. This is why fueling areas are specified with locking grate systems and a load class above what the site's car count alone would suggest.
Load class guidance
Follow the tanker, not the average car. Fuel-island lanes and tanker offload paths sit in Class D (extra heavy duty — the class our Load Class Recommendation Guide lists for fuel and freight traffic), with Class C as the floor anywhere trucks can physically reach. Canopy-edge and perimeter runs that only ever see passenger cars can drop to Class B–C. When in doubt, rate the run for the heaviest vehicle with access to it.
Recommended systems
Quote-only · Fuel islands & tanker paths
ACO PowerDrain with PowerLok ductile grates
ACO PowerDrain is the forecourt spec: polymer concrete channels with ductile iron grates held by the boltless PowerLok locking system, so braking and turning tanker traffic cannot walk them loose. PowerLok grates carry EN 1433 ratings up to Class F (grate-dependent — ratings are published on each grate's product page). The 4-inch S100K system handles most island and drip-line runs; wider systems are available for high-flow pads.
Quote-only · Perimeter & canopy edge
ACO KlassikDrain
For the runs tankers never touch — canopy edges, car-only lanes, storefront aprons — ACO KlassikDrain uses the same channel family with a broader, more economical grate catalog, including ADA-marked patterns for the walkway between pump and store. One quote can package both lines so each run carries the class it actually needs.
Quote-only · Mineral channel body
BG Filcoten trench drains
Filcoten channels are fiber-reinforced concrete — an inorganic, mineral channel body with ductile iron grate options rated to Load Class E. Worth considering where the project spec favors non-polymer materials; verify chemical compatibility for fuel-contact service with the manufacturer's documentation, which we can pull into your quote. Line details in the Filcoten FAQs.
In-stock · Lot corners & landscape
Catch basins for the rest of the site
Away from the pad, catch basins at lot low spots and landscape islands handle general stormwater on the storm side of the site — keeping the forecourt's contained system separate from clean runoff.
Heavy vehicular castings from EJ and US Foundry, and Josam trench systems, are available on request — ask when you request a quote.
