Tank 5857
Dimensions: 64’Ø x 21’ tall
Tank 5857 is equipped with an internal cathodic protection system to protect the submerged tank surfaces again corrosion as well as a soil-side cathodic protection system to protect the bottom against corrosion. Records indicate that the interior cathodic protection system is an impressed current system with 24 type FW cast iron anodes suspended from the tank roof. Field Inspection shows that the interior tank anodes are mixed metal oxide wires. The soilside system is an impressed current cathodic protection system consisting of 4 vertically installed anodes.
