Description
ModuTank’s unique 100,000 gallon water storage tanks, proven internationally for more than 50 years, are the ideal solution for your water storage needs. They feature compact, hot-dip galvanized steel components, designed for rapid bolt-together assembly in hard-to-reach indoor and outdoor locations. Our tanks are ideal for sites with limited access. Included footing plates allow free-standing, rapid installation on most flat, level surfaces with minimal or no formal site prep, or, if available, they can optionally be anchor-bolted to concrete foundations. One-piece membrane liners, specifically chosen for your water storage needs, line the tank’s interior, shielding the galvanized components and protecting the stored water from contamination and environmental leakage. Our NSF/ANSI 61 certified liners are safely utilized for storing potable and drinking water.
While 100,000 gallons is a standard size in our product line, our water storage tanks are available in sizes ranging from 500 to over 2,000,000 gallons. Modutank Inc. products offer the lowest containment costs, compared to Others, when considering the tank, shipping, site preparation, and installation costs.
