Several factors lead companies and consumers to choose double-wall underground storage tanks, whether or not they are required by law to do so:
- Xerxes fiberglass double-wall tanks are rust-proof, maintenance-free and formulated to be compatible with all petroleum fuel products, alcohols and alcohol-gasoline mixtures.
- Two walls of protection allow for maximum security - in the unlikely event of a leak in the primary wall.
- Xerxes tanks offer a full 360 degree secondary containment. Unlike other types of double-wall or jacketed tanks, the secondary containment can be pressure tested at the installation site both prior to and after installation.
- Various types of monitoring devices can be installed in the interstitial space inherent in double-wall tanks. With Xerxes' TRUCHEK® Hydrostatic Monitoring system, owners/users are able to conduct a tank tightness test that meets EPA criteria and has Underwriters Laboratories third-party verification .
