This may not look like a retention pond, but that's what it is.
We were told by the good folks at Buncomb County that we needed a retention pond to handle
storm water runoff. But, since we didn't have room for such a pond, our
engineer in charge (my son Trip) designed a substitute pond to hold runoff and release it gradually.
Very clever idea.
The pipe is 30 inches in diameter, and sufficiently long to have enough volume to do the trick.
It will be capped eventually (you can see the part of the cap in the lower left corner) to make
it a true water holder. The cap has a hole to allow the held water to dribble safely away.
The top of the pipe has an emergency overflow cutout.
Here is the entrance to the storm water reservoir.
The trick is to slowly discharge water without getting sediment in the pipe.
Trip has already shoveled out sediment once from this pipe and to prevent a revisit of that
Trip has already shoveled out sediment once from this pipe and to prevent a revisit of that
he designed this sediment/kid/assorted animal barrier. This was hard going in hot weather.
Its good to have our own engineer on the project.
