Ultra Containment Sump — 110% Secondary Containment for 300–1,000 Gallon Fuel Tanks

Code-Compliant Secondary Containment for Fuel Tanks 300–1,000 Gallons

The Ultra Containment Sump delivers the built-to-spec secondary containment your EPA SPCC plan requires. Constructed from rotationally molded Linear Low Density Polyethylene, it's available in three capacity tiers—360, 605, and 1,100 gallons—each sized to meet the 110% spill capacity threshold for its matched fuel tank. Choose rigid for stationary installations or flexible for portable, easy-storage deployments. Both designs come with or without a 3/4" drain. Ships free to your site.

Spec'd Right for Your Site Before It Ships

The Ultra Containment Sump provides the secondary containment your EPA SPCC plan demands — but only if you select the correct capacity for your tank size. We verify compliance requirements for your state and application before the order ships. If your 550-gallon tank needs the Ultra 550 model with 605 gallons of spill capacity to satisfy the 110% rule, we confirm that match before you buy. No guessing. No post-delivery compliance failures. Select from rigid or flexible configurations with or without a 3/4" drain based on your site's stormwater management needs. We catch the wrong spec before it becomes a failed inspection.

Field-Proven Polyethylene Handles Real Site Conditions

Field-Proven Polyethylene Handles Real Site Conditions

Rotationally molded Linear Low Density Polyethylene gives the Ultra Containment Sump its field-proven durability. This material resists cracking, UV degradation, and chemical exposure from diesel, gasoline, and other hydrocarbons. The rigid version handles stationary installations where the sump stays in place under your fuel tank. The flexible version folds flat for transport and deploys quickly at temporary job sites or remote fueling locations. Both designs maintain full 110% containment capacity. Choose the configuration that matches how your operation actually works — not what a generalist catalog assumes.

Passive Stormwater Filtration Cuts Manual Pump-Out

Passive Stormwater Filtration Cuts Manual Pump-Out

The optional 3/4" drain paired with the Ultra Self-Bailer turns a containment sump into a passive hydrocarbon filtration system. Rainwater and stormwater collect in the sump, pass through the self-bailer filter, and discharge clean water — while hydrocarbons are trapped and contained. This eliminates the manual pump-out routine that slows down site operations and creates handling liability. The no-drain configuration retains all liquids for controlled removal when your site protocol requires it. Either way, the sump does its job without adding tasks to your crew's workload.

Sizing Compatibility

Match your fuel tank capacity to the correct sump for code-compliant 110% containment.

  • Fuel tank capacity is between 300 and 1,000 gallons
  • Site requires 110% secondary spill containment per EPA SPCC
  • Installation location is above-ground and accessible for sump placement
