I sometimes watch a concrete YouTuber. He recently did a manure pump pit. I honestly didn't realize the scale of manure management. A massive holding tank for all the produced waste. All the areas with cows will have ways of pushing and moving that manure out into trenches and eventually into a massive pit. The pump pit was so they could get to the lowest point and pump the product into its next stage of processing / use. Its a valuable byproduct so worth dealing with but just never thought about what goes in must come out, and cows eat a lot.
