Most states and municipalities haven’t made updates on laws guiding and governing hygienically-treated human waste. You could get persecuted or even fined for using a waterless toilet.
Ensure, to double-check with the local authority before you buy one. Normally, if you are in a rural area with an ample amount of land you need not worry. These are made for rural use and cabins. However, most urban and suburban areas won’t permit such, you could imagine the reaction from your neighbor if they find out you are composting feces in your backyard.
Ensure to adequately review the dimension of your desired toilet, and compare them with your available space. Because they do not require piping, they have a larger footprint compared to your conventional loo. For moving homes like trailers, tiny houses, and RVs space is a valuable resource.

How to Get Rid of the Solid Waste
You need to think carefully about how to get rid of the solid waste because human waste can pollute the environment and make people sick. Ensure to have a sizable compost bin, preferably two compost bin – I always go for the rotating bins. Select a bin sealed enough to prevent leaching of liquid on the ground but not airtight. It takes about a year or more for one bin to get full (depending on the number of users), start using the second bin if the first get filled. When the second bin is full, the contents of the first can be used for manure on non-edible plants.
