Salt Water Disposal (SWD) Site Bonding Guide for Lightning Protection
Electrical storms create a charge on an SWD site. This induced charge includes the surface of the earth, fibreglass tanks, steel tanks, and other structures and operating systems at the site. When there is a nearby lightning strike to the earth, which can occur more than 100m from the site, the charge that was induced on the earth is discharged to the point of lightning termination in a matter of microseconds.
In order to reduce the potential of an arc or spark within the containment wall tank area, all isolated metallic bodies on top of fibreglass tanks should be bonded and connected to the unified ground system.
