Hello Sukanya and welcome.
Like Paul, I see no reason to remove the watermark if it's just going to be retyped. The entire text is legible. The effort required would be troublesome and should not even be considered for this scenario. As long as there is no color variation between the mark and the text, there's no method for easy isolation and selection of the watermark.
"....This is just one file paul, i posted an image that is clear, i have several other files that totally beat me...."
I can see your point of the watermark causing legibility problems, but as long as the other files are similar to this one and the text color is the same as the watermark, then you will have the same problem.
Sorry that ther is not an easy answer here. Maybe someone else will have a better idea. Good luck.
