Fracking is a drilling process used to access gas and oil deep in the earth. A high-pressure mixture of water, sand, and chemicals are injected into rock formations deep in the earth. The created cracks release the gas or petroleum, so they flow more freely. Frac tanks hold the water mixture on site until it is released into the ground.
While cities and counties rarely engage in fracking themselves, frac tanks and other fracking equipment can be used for other purposes as well. Clarion Municipal's standard used 500 BBL frac tank holds 21,000 gallons of liquid. Such a large amount of transportable storage is valuable across a wide range of municipal departments.
