Simple poop water disinfection solution

[Ragnaman]

Early game tech, a speck of refined copper necessary for electronics.
the alternative would be - germ sensor - requires plastic.
I use a mod that makes airlocks (on auto) not to allow gas to pass (because i dont like to faff around with waterlocks).
Container could be completely isolated and submerged in chlorine as well, eliminating the need for airlock.
Focus is on timer usage and germy water loopback into container if timed valve is closed.

water circulates back into the tank until the timer opens the valve and timer is eyeballed to a moment when all germs are dead from chlorine. Throughput is not perfect but latrines never need big throughput from sieve.
sieve never gets germy water,
accumulation of polluted water for whatever other use.
no gimmicky use of airlocks to disable water container.

what you think ? probably there can be improvements ? As soon as i have mechatronics i plan to automatically pump out the polluted dirt from the room.

I just loop it back to the wash basin and latrine after sieve, weirdly that is working somehow...
The excess goes to Electrolyzers, the clean air kills the food poisoning germs really quick before they cause harm.

The most obvious issue is that airlocks are not in fact airlocks so all the chlorine will escape since dupes need to run into that room all the time to refill the sieve and take away the polluted dirt. Putting the sieve in the chlorine room is completely unnecessary and a really dumb idea. At least use a liquid lock or something.

The second problem is that your questionable piping allows germy water to flow past the reservoir to stand in the pipes (where germs won't be killed). This is why players make "gimmicky use of airlocks to disable water container[s]".

Another problem is that the reservoir will eventually fill up (because automation only opens the 5kg/s outflow for 23% of each cycle), at which point polluted water will skip the reservoir entirely and go straight to the sieve.

Just build one or ten inline reservoirs in a sealed chlorine room without any fancy piping or automation and it will work much better than this.

True about airlocks, i use a mod that makes them not allow gas to pass through (on auto) because waterlocks exist in vanilla. Hmm, should mention in the OP, but i could just keep that container completely isolated from everything else too.

Water is looping continuously until it stops being germy (cant really tell the water movement from picture), that is why the timer is there, it activates the valve (opens it) once the container outputs only polluted water without germs. When valve is closed the germy water loops back into container to be disinfected.

Yes the container will eventually fill up, but by that time i will find a use for it.

yeah, i never understood why washing hands with germy water somehow just works...but then again when i started ONI i also tried to make a water reservoir above my toilets, thinking that water pressure in pipes is important

I tie my bathrooms to reed plants. They drink up the dirty water I get free reed fibers for doing nothing but letting my Dupes flush toilets:)

[Ragnaman]

Yeah ive used reed before, that is a good self sustaining loop.

Make sure the valve is closed a bit before bathroom scheduled time or the sewage from the bathroom won't cycle to disinfection.

If you have multiple shifts of workers take them all into consideration so you don't open the valve too soon.

I think you have some good ideas here. I do something similar when I get to plastic - I set up drecko farms as early as a I can to get those glossies spawning. We all play differently, and nothing in your set up is "wrong", if it works for you - go for it. Chlorine can be really handy for things like this.

[Moriibund]

Ever since I learned of it... I fill 3 tanks with a feed back loop, by the time all 3 tanks are full I have the room they are in filled with chlorine, this setup requires zero automation or refined metal/ plastic, can handle a constant 10kg flow, disinfects 100% of all germs, and requires no power... Can't beat it.

[Alucard †]

I wanna try this but gathering enough Chlorine from the tiny pockets scattered around the area and making sure it doesn't leak too much gonna take a while..

[Bravo]

I typically find it easier to set the room up with bleach stone. Vacuum out the room with a liquid lock and pump (or liquid lock and tile construction/destruction), put a storage in temporarily, set to bleach stone. When some bleach stone arrives, deconstruct the storage and brick up the room. You don't need much chlorine, just enough to have presence over the relevant tiles.

[Alucard †]

Oh right i keep forgetting about the solids off-gassing mechanic.

[caseyas435943]

Don't put your sieve in the room. Use the sieve after the water comes out of your room. That way the dirty will not have germs on it.

You can clean water with 2 storage tanks and doors under them. Until the tank is full the door is closed.

Most use 3 tanks with a loop piping setup so the water never stops. Once you get 5 tons in the tanks the water is clean and you'll never take water out fast enough to get germs in the last tank. As long as they are full.

You could be hands on. A shutoff to turn the dirty water off. A shutoff to stop the clean going out. Then when the tank is full. Turn off the incoming. When it's clean to on the out going.

Or a filler gate. Set it to 200 seconds. That gives anything in the tank time to get clean. A green opens a door under the tank letting out the clean water. A red to a shutoff stop to the new water from getting in.

Fully automated with 1 tank. No germ senor needed using the filler gate and the door under the tank. 200 second is more than enough time to clean the germs from the water. If not (I've never seen it in any game I've played.) You can chain use 2 filler gates. For a longer times.

Also, the pdirt won't potentially disrupt the chlorine by offgassing into it. This won't happen if there's enough chlorine, but it may not reliably work with just the bleach stone trick, you'd need a vent.
