Hey guys, I'm new here, but wasn't able to find an answer to this question from a forum search, so here goes...

I recently got access to an old impoundment that was drained years ago. We have fixed the levees, but the impoundment still drains through a 12 inch pipe. Due to overgrowth and sediment buildup, it is extremely difficult to reach this drainpipe on the wet side to install any sort of standpipe... So my question is this. Would there be a way to install a standpipe on the outflow side of the drain pipe? It would be much easier to work with on that side, but of course I am worried about water building up and ultimately pushing the standpipe off...

In a nutshell, is there a way to secure a standpipe to the outflow side of a drain pipe, without fear of it popping off? Thanks!
