Working with an engineering firm on plans for a 22-24 acre pond that will incorporate an old 6 acre pond that was drained about 10 years ago. All the engineering plans call for a vertical stand pipe with a trash rack, but I am concerned with the need to add a structure over the standpipe to force water to be drawn from 4-6+ feet below the surface. The pond will be about 25 feet at the deepest point and a good deal of the area will be over 10 feet. I can't seem to find much online in products designed to extend down over a standpipe that deep or a trash rack that extends more than maybe 1 foot down. Any thoughts or suggestions on where to look for design plans or premade structures?
