1-2100-EVR Series Thread-On Spill Containers

OPW and Pomeco Spill Containment Manholes are designed to prevent spilled product from entering the soil near the fill and vapor return riser connections on underground storage tanks during normal tank filling operation, or in the event of tank overfill. The spill containers catch spillage to help prevent soil contamination and groundwater pollution. OPW Thread-On Spill Containment Manholes are generally used on new tank or riser pipe installations.

Features & BenefitsOrdering SpecificationReplacement PartsDownloads


  • Easy Installation – Reduces job-site time and installation costs. OPW Thread-On Spill Containers screw directly onto 4″ NPT riser. No external connections to make; adjust the final grade height and support the unit with backfill.
  • Integral Pull-to-Open Drain Valve – Allows high-speed drainage of excess product into the tank. Designed with a convenient self-cleaning seal and removable screen for easier component cleaning.
  • Capacity – Available in a true 5-gallon capacity as well as 15-gallon capacity.
  • Rain-Shedding Cover – Available in either cast aluminum or cast iron, this unique design incorporates a seal in the underside of the cover. The seal seats between two dams on the mounting ring to prevent surface water from entering the spill container.
  • Fuel Compatibility – Designed to accommodate the fuels of the future, including methanol, ethanol and fuels with MTBE additives.
  • Product Identification Tags – Available for both the cover and bucket to positively identify the product contained in the UST with standard API symbols. (See product I.D. tag specification page for more information: LINK)
  • Heavy-Duty Mounting Ring – The angled ramp design offers superior protection against snow plow and traffic damage, and provides for secure concrete anchoring.
  • Corrugated Bellows – can be adjusted +/- 1 inch for desired grade level.
  • Duratuff® II or Cast Iron Base – Composite Duratuff® II material is lightweight, durable, and conductive. A rugged optional cast iron base is also available.
