Yes, rainwater collection is legal in Nebraska, but subject to state water rights laws and local ordinances. Neb. Rev. Stat. § 46-226 permits residential rainwater harvesting for non-potable uses, while commercial systems may require permits from the Nebraska Department of Natural Resources (NDNR). Recent 2026 compliance updates emphasize prior appropriation rights, particularly in over-appropriated basins.
Key Regulations for Rainwater Collection in Nebraska
- Prior Appropriation Doctrine: Nebraska adheres to “first in time, first in right” water rights. Unauthorized collection may infringe on downstream users’ rights, per NDNR enforcement guidance.
- Permit Requirements: Systems exceeding 5,000 gallons or serving multiple dwellings trigger NDNR review under Neb. Admin. Code Title 246, Chapter 2.
- Local Ordinances: Counties like Douglas and Lancaster impose additional restrictions (e.g., structural standards, setback rules) enforced by local health departments.
Compliance hinges on system scale, location, and intended use. The NDNR’s 2026 Water Plan updates prioritize conservation but retain strict oversight for large-scale projects. Consult NDNR’s Rainwater Harvesting Guidelines for project-specific requirements.
