west central Iowa
We had a county tile project come through us last year. That branch of the drainage district was around 600 acres. Engineer ended up with 24” concrete, on the last 3/4 mile. We have decent fall also.
Contractor said 500’ dug in with excavator was a good day for 3 people. They had some 10-12’ cuts.
Tile main drainage coefficient?
