Anatomy of a LUST (continued)

Installation of New Tanks

Following removal of the LUSTs, new tanks are installed with up-to-date protection against corrosion and leaks. Both steel and reinforced fiberglass are used for new tanks. New steel tanks are protected from corrosion by non-corrosive coatings (fiberglass, resin, Glasteel®) or by cathodic protection (e.g., sti-P₃® system) and constructed in double-wall configurations.

More careful tank installation techniques are also used. Anchors are installed to guard against tank flotation by a high groundwater table. Liners are included to provide secondary containment.
