Highland Tank’s OP Tank is designed to eliminate the worry, the mess, and the danger of aboveground storage tank overfills. Highland’s OP Tank captures and stores delivery overfills resulting from mistakes or failures during filling operations. Our patented design safely directs the overfilled product via the Overfill Protector into the OP Chamber. The OP Chamber is large enough to contain a spill of at least 20% of the tank’s storage volume.
