Maximum Lateral Length
What is the maximum length of a single-wall corrugated lateral drain pipe?

To get the fastest water entry into the pipe, choose a 4-inch 8-row lateral drain pipe. To save on cost, go with a 3-inch 4-row pipe that will give you a similar water entry rate into the pipe as a 4-inch 4-row pipe, but the 3 inch costs less than the 4 inch.

Choose a drainage coefficient that is greater than or equal to drainage intensity.
