There is not an overflow on a holding tank for pretty obvious reasons.
There should be the inlet from the herad, the outlet(s) and one or 2 vents. Usually these are all on top but sometimes a pumpout is on the bottom. It sounds like you have a crack or other leak that has to be fixed. Best to get it pumped out and remove it for repair or replacement asap.
