Long format drainage recommendations

Hey guys, I'm still designing the warehouse set up and am looking at the various methods of drainage. I'm going to have 40' rows with a floor drain at the end of each row. In the past i have used corrugated plastic panels with a gutter ran down the side of the wooden (2x4) tables, or drained each 4x8 grow table into its on basin.For this project i want to eliminate porus surfaces so the wooden table have to go, I'm wondering if the gutter system would still be !y best option considering g o could run it the entire length of the 40' table Nd not a have a bunch of p!umbing of potential clogs to deal with.

I'm seeing all kinds of tables being used in commercial grows, everything from wood to steel with mesh bottoms and a huge catch basin the runs the length.

Greenhouses use large flood and drain tables that are easy to clean/spray. Some are on roller systems to allow easy plant care.

Graded floors and gutter style floor drains.
