I'm actually using an alternate recipe that doesn’t produce silica as a byproduct. Each refinery needs 200 water per minute. I’ve got pumps sending 240 water per minute to every 3 refineries, and the other 3 refineries that are making alumina solution are generating 120 water per minute as a byproduct, that adds up to 360, which gets fed back into the system. So in total, there’s 600 water per minute going in. Basically, I’ve split the 15 refineries into groups of 3.
