I want to build my first composting toilet to use in a trailer. The thing is, ever since I've been to India I use the Indian way (one cup of water and one left hand)
Can this work with dry toilet? I mean, I thought about it, sometime bowl movements can be pretty watery or sometimes theres diarrhea . Is it possible just to use more sawdust or something?
Okay I'm not sure what you mean about the cup of water and left hand thing but I think if you add water it's fine, you do yes just have to add more sawdust. It also may throw off your nitrogen/carbon ratio so you might have to tweak it and add more "greens" but we pee in our composting toilet and it composts no problem. We just have to make sure to use enough sawdust to absorb everything.
Just me and my kids, off griddin' it - follow along our shenanigans at our YouTube Uncle Dutch Farms.
Congratulations on committing to a composting toilet!
I live in India, with composting toilets at our school, so I am very familiar with precisely your issue. At our school even without any people from the plains of India using water, we just have an increasing population at our school every year, and the toilets have been getting too wet. When we have a lot of Indians (from the plains) staying at our school, and if they all use water, the smell changes to something swampy. We do use sawdust, and our climate is extremely dry, but this happens.
We don't have any kind of active ventilation or drainage in our humanure pile down there. If we did, I think it would mitigate this problem. Also, our manure chamber below the user's room is kind of huge, and I believe that if fewer people were using such a large manure chamber, there would not be much problem. Our system has two large manure chambers under each user's room, so we have an alternating year system, where we remove the manure after a year. We don't carry buckets or anything, just poop right down the hole onto the manure pile, and throw a shovel of sawdust, dry earth, or leaves or whatever down.
If you can't add active ventilation or passive drainage, or a huge manure chamber, you could reduce moisture by peeing in a container and taking it outside to the compost pile or trees or mulch basins. And really, the thing to do is just to start using your composting toilet, and if it smells swampy or there is some other problem from the excess moisture, then take steps. But who knows, it might just work fine as is.

Thank you Bethany.
And thank you Rebecca for your answer.
I think you are right, I will build it and see how it goes.
I plan to build one similar to 'Nature's Head' with a urine diverter, agitator and maybe also a ventilator so I think it'll probably be ok.
Btw I didn't knew it's different in the mountain area. Haven't been to the north yet and I hope it'll happen very soon
