Basically the setup purifies all inert xircon effluent from xircon and heavy xiranite production into xircon effluent, combines it with xircon effluent from purification nodes in the test area (conduits on top of the image), and redistributes it between xircon and heavy xiranite production. This lets me maintain enough xiranite to constantly produce 1.5 cuprium and 1 xiranite gear components while producing 14.2 batteries/m and 12 heavy xiranite/m.

All excess sewage gets piped into a purification node. Xircon doesn't need a sewage supply, just a xiranite supply to get rid of the sewage that xircon generates as a byproduct.

Edit: The 9th cuprium refinery in between the battery production is temporary. I've just added it to get rid of my cuprium stockpile now that we can convert sewage into something useful.

I remembered that you can power offensive towers with batteries. And because towers only consume energy when they fire 50 SC batteries give pretty much unlimited supply of power. Decided to take advantage of this and tower up my alluviums.

Basically when the events ends all gourds will be auto-exchanged for stockbills bypassing the outpost stockbill production limit. If you amass 68K gourds you'd get 2,720,000 bills and there is also a 2nd stage of the event which allows you to produce jade gourds which should also be stackable to 68K and I'd assume they would be much more expensive.
