Enforcement Reality
The Nebraska Department of Environment and Energy (NDEE) does not regulate waterless composting toilets under Title 124. Enforcement is minimal, but a separate, approved system for greywater is still required.
A common mistake is connecting a composting toilet to a water source, which would then make it subject to state wastewater regulations. Another is failing to have an approved system for all other wastewater (greywater).
Local Exceptions
None identified. State law applies uniformly across Nebraska. Local ordinances may still vary — check with your city or county government for any additional rules.
Bottom Line
Composting Toilets are legal with restrictions in Nebraska. This activity is permitted, but specific conditions apply. Violating those conditions can result in fines or criminal charges. Read the rules carefully and consult an attorney if unsure.
