Sewer - Composter - planter Ratio


Recommended Posts

I'm kinda new to this forum, so forgive me if these questions had been asked before.

So, I'm trying to have a mushroom and tree farm (each type of sapling is 1x1) with fertilizer and I was wondering, how many animals you need to keep up with the usage of the industrial fertilizer.

I did some searching and to my understanding, 23-24 cows/sheeps are the optimal value that one sewer can handle (CMIIW).

Which leads me to my next question, how many sewers and 1x1 planters can a composter handle?

I also heards that liquiduct have a limit and can bottleneck your sewage output from your sewers. If it's true, what's the limit?

So I did some testing myself and the result is, to be honest, quite unexpected..

Anyway, I'll just share it here in case it helps someone else.

Note: to make it easier for myself, 1 sewage tick (ST) = 1.5s

Based on my testing, it seems that both liquiduct and golden waterproof pipe can output all 1k mB in a sewer before the next ST starts to kick in.

I also tested how many cows (or sheeps) can a sewer handle in one ST, and the result is 26.7 mB/cow every ST (26 rounded down, which is the same with wiki).

Also, contradictory to the popular belief that one sewer can only handle up to 24 cows, a sewer can handle up to 37.4 cows or 38 rounded up.

Putting 37 cows to one sewer will net you 987 mb sewage per ST (which is close to the 26.7 * 37 = 987.9 calculation).

Which leads us to our question; how many composter can a sewer handle (or simply put, the sewer : composter ratio)?

To do this, I do "x" numbers of cows hole (38 cows per hole) into liquiducts that connects to "Y" number of composter.

First, I do 1:1, 1:2, 2:3 for the X:Y ratio.

For 1:1, the sewage keeps pilling up in the composter (more income than usage).

So I went with 1:2 and see that the income can't keep up with the usage(less income than usage).

When I increased the ratio to 2:3, there is a small gain per ST that keeps accumulating in the composter (still more income than usage).

By going with the 3:5 ratio, I could see that the usage is still slightly higher than the income (but with very little difference). I thought it was good or optimal enough and just went with it.
