The liquid fertilizer industry commonly uses Flexible Polyvinyl Chloride (PVC) Secondary Containment Liners to meet state requirements for aboveground storage tanks. Most secondary containment methods act as catch containers, only contacting the product when it leaks from the tank. In contrast, a flexible internal PVC tank liner offers a different approach with added benefits.

Tank Liners are Primary Containment

PVC tank liners sit inside the aboveground storage tank, unlike most other secondary containment methods that are outside.

Two Main Benefits of PVC Liners

Using a PVC tank liner offers two main benefits: longer tank life and lower cost for required containment.

The life span of a tank partly depends on how long the shell material and welds withstand exposure to the stored product, weather, and water. A PVC liner creates a barrier between the potentially corrosive liquid product and the tank shell and floor. This barrier reduces exposure to corrosive products, potentially increasing the tank’s life.
