European suction-style piping must
meet the same requirements as
regular product piping
Ball valves or other means of isolation
need to be installed to allow line
tightness tests to be conducted

Siphon bars must meet the same
requirements as regular product piping
All single-walled or metal components,
including copper tubing used to
maintain siphon must be contained
Ball valves or other means of isolation
need to be installed to allow line
tightness tests to be conducted

For mechanical ALLDs to work properly,
only one STP can be running at a time

Reminder: If cabinet-style dispensers
are installed, they must have UDC

12,000 gallon – 10’ diameter Xerxes DW FRP tank
100% Volume = 11,904 gallons
90% Volume = 11,904 – 1,190 gallons
= 10,714 gallons
Length of Ball Float = 118-3/8” – 98-5/8”
= ~19-3/4”

UST System Design
UST system designs must be
engineered to prevent tanks from
becoming buoyant
• Concrete deadmen
• Concrete hold-down pad
• Overburden
Anchoring
![Page 20: UST System Design - North Carolina Management/DWM/UST...UST System Design •European Suction Piping •Tank Manifolds (Siphon Bars) •Piping Manifolds •Transition Sumps •Marinas](https://reader034.vdocument.in/reader034/viewer/2022051511/601d45dcefd7eb0bec22a35d/html5/thumbnails/20.jpg)
Tank buoyancy calculations should be
made assuming an empty tank that is
completely submerged

apply to new components installed
Hint: Hydrostatically test containment
sumps that will be used as part of the
leak detection system prior to beginning
