fixing small hole in sewer pipe

I have a very small leak, about 3/16 or less, on my drain pipe coming from the black water tank. The hole looks like it was caused by someone running a screw underneath to hold the cover on the belly. It is located on the side but still leaks liquids when emptying my black tank. Anyone know of anything that I can use to seal it up or if the Eternabond tape would work on this.
