While competitor coated leachate tanks can corrode from the unpredictable leachate composition within the first few years of use. Because of Aquastore’s proprietary glass-fused-to-steel technology, our tanks outperform any other leachate storage tanks, making it your best choice to contain the aggressive and hazardous liquids found in today’s leachate storage facilities.

Federal and State standards require secondary containment when storing leachate. Aquastore offers secondary glass-fused-to-steel tanks for leachate applications as an auxiliary line of defense should accidental spillage occur. Aquastore primary and secondary tanks are flexible in design and can expand to meet your growing leachate capacity.

Oil & Gas

MASSI has decades of experience supplying storage systems that stand up to the most corrosive liquids. We know that every frac water storage system is unique, and we work collaboratively with oil and gas clients to determine the best tank solution for their needs.

MASSI offers the very best in coating technology and tank longevity, even if that means that our tank solutions are not the lowest price on the market. We believe that what energy companies may save in initial installation, they typically pay for in lost production due to maintenance, repairs or even tank replacement. It is neither cost effective nor safe to use subpar tank coatings to store volatile substances.
