OneSump Spill Containment System

The OneSump spill containment system provides the highest level of environmental spill protection by combining all tank openings into a single enclosure to minimize leak paths. In the OneSump, the fill port spill containment, vent risers, turbine and ATGs are secondarily contained to prevent leak exposure. In addition, any overfill of the 15-gallon containment bowl is diverted to the tank top containment sump rather than at grade. In extreme overfill events, this effectively turns the OneSump into a 200 gallon or more spill containment system.

Highlights/Advantages

  • Single Containment Sump: Combining all tank openings into one single containment sump minimizes potential leak pathways and reduces construction time and cost.
  • Easy Access: Full access to the sump is possible in less than a minute.
  • Customize: Layout of piping within the OneSump is pre-engineered to assure rapid installation.
  • Spill Containment: 15 gallon primary spill containment provided by an aluminum bowl assembly with two vapor and fill riser sections.
  • Compatibility: Stainless steel flex lines, Viton gaskets and innovative single pin clamps greatly simplify access to product and vent piping.
  • Appearance: Reduce concrete maintenance and increase forecourt appearance with everything under one multiport containment cover.
  • Full Customized: Let us simplify your tank containment needs from design to installation. Each OneSump package is fully customized to meet your site specific containment, piping, pumping, filling, vapor recovery and inventory level monitoring needs. A single package part number is provided to simplify the order process and each package is delivered sealed to the site in one box to ensure all components arrive at the same time.
  • Installation, Access, Maintenance…Simplified: The complete OneSump System provides innovative components and installation techniques to provide one of the most user-friendly containment solutions in the industry. From the installation to the maintenance stag, the OneSump offers easy to use components which are designed with the technician in mind.
