Our containment sumps offer the same benefits as our tanks

Virtually all double-wall tanks installed today have containment sumps for secondary containment around tank fittings and manways. Customers choose Xerxes factory-installed containment sumps for the same reason they choose our tanks. They are made of corrosion-resistant fiberglass and designed for the highly corrosive envirnoment that exists in containment sumps when storing biofuels. Our containment sumps and collars come in a variety of models and sizes, all engineered to accommodate customer's project needs.
