WebbAs the name implies, gravity drainfields work by letting gravity drain effluent from the septic tank into a series of trenches. This means that a gravity drainfield area must be below the draining level of the septic tank. If this is not the case, then a pump tank is necessary and it is called a pump to gravity system.
