Liquid transport problem
Objective: To transfer 4000 liquids per second over a very long distance.
In the original game, I can place four parallel pipes by placing a pump every 20 underground pipes (10 empty spaces between four pairs of pumps).
How to solve this problem by means of mod? (of course it is necessary to use underground pipes)
Install a non-return valve every Y underground sections.

Bandwidth table for the mod:
Distance (in underground pipes, two for 1 space) between valves. Flow.
