Econo Rank and Quickstor Liquid Storage



One of the most popular units for temporary jobs.

EconoTanks offer versatile liquid storage for environmental, industrial, commercial and agricultural use, including chemical, potable and wastewater storage. The 4’9” high EconoTank is available at per-gallon containment costs below those of other storage systems. Modular EconoTank components, engineered for hand-carrying and rapid bolt-together assembly by workers using common hand tools, sharply reduce installation costs. Also, no special skills, cranes, welding or scaffolding are necessary. Shipping charges are minimized through efficient, compact packaging of modular components on skids sized for flat bed shipment. For example, the steel for a 2,000,000 gallon EconoTank can ship on a single flatbed. EconoTanks are economical alternatives to standard tanks, lagoons, ponds and fractanks.

EconoTank Features

Econotank-2.jpgEconotanks are available in capacities from hundreds to millions of gallons in rectilinear sizes from 8’ x 8’ upward based on 4’9” high x 3’9” wide modules. Special shapes with right angle corners such as “L”, “U”, “T”, etc.  Custom tanks are possible to meet site or special flow requirements. Free-standing EconoTanks install on any firm, level surface with little or no site preparation utilizing our anchor plate and above-ground ballast system for short-term installations or where ground penetrations are not desirable. Alternatively, EconoTanks can be anchor bolted to concrete foundations for permanent installation.

EconoTank Covers

Floating covers fabricated from the same flexible membrane materials as liners are available as options for creating totally enclosed systems. Covers, buoyed up by floatation logs, ride on the fluid’s surface and create practically vapor-tight enclosures. Insulated floating covers are available. (Click-to Covers)
