Tank Sumps

Tank sumps are protective enclosures for pumps, piping, and other accessories above the tank top. Tank sumps should be watertight and durable, since they will protect the surrounding environment in the event of a piping leak. For 25 years, Containment Solutions has been perfecting the fiberglass tank sump design and installation process to create the most reliable and contractor friendly sump line available. Our proven technology has been utilized in thousands of installations. Containment Solutions tank sumps with a patented EZ-Fit adhesive channel carry a 30-year structural and corrosion limited warranty, which is the most comprehensive limited warranty in the industry.

Single-wall Tank Sumps

Containment Solutions tank sumps are manufactured using the same technology as our fiberglass tanks. We use a special blend of glass and resin that is carefully metered during fabrication to ensure a consistent wall thickness. Containment Solutions non-corrosive fiberglass tank sumps are light enough to be installed without mechanical equipment, yet durable enough to protect critical components for decades. Tank sumps typically fit on the same truck as the tank, which reduces shipping expenses.

Double-wall Tank Sumps

Containment Solutions has earned a reputation for double-wall reliability as a result of our hydrostatic tank monitoring technology. We have adapted the same expertise to the fiberglass tank sump. Containment Solutions double-wall tank sumps were designed to satisfy current regulations, while anticipating future requirements. Unlike competitive products which bond the inner and outer sump walls together with fiberglass fabrics, Containment Solutions double-wall sumps are built with 100% separation between sump walls. This open environment offers an unobstructed pathway for fluid monitoring to reduce trapped air that can cause false alarms, and provide 360° protection and true secondary containment. Our double-wall hydrostatically monitored tank sumps are an integral part of the Containment Solutions HydroGuard® System.

Entry Fittings

Containment Solutions offers a line of UL-971-rated FRP Sump Entry Fittings designed for use with both conduit and FRP pipe. Our Bonded Sump Entry Fitting - Termination Style provides a water-tight seal, up to 5-degrees of adjustability, and a built-in test port. In addition to a 30-year warranty for Corrosion, Materials, and Workmanship, this patented product also comes with a 30-year Water-Intrusion Warranty.

Deadmen Anchoring System

Containment Solutions (CSI) can provide pre-fabricated deadmen tank anchors engineered to American Concrete Institute (ACI) standards. Deadmen anchors provide a means to prevent installed tanks from floating up when ground water is around the tank when installed properly and in accordance with the current CSI installation standard. Deadmen anchors are as effective at preventing tank flotation as a concrete pad, but less costly.

Containment Solutions deadmen allow the connection of the fiberglass hold-down-strap-end to the deadman anchor point using wire rope, turnbuckles, or other mechanical connections. The deadmen are manufactured with slots that allow the anchor points to be easily moved along the deadmen for alignment with tank anchor points during installation. The deadmen type, lengths, and number of anchor points are dependent upon the tank diameter, model, and capacity.

These accessories and more can be supplied by Containment Solutions and will arrive with your storage tank to save you valuable time and expense.
