Nebraska Grease Trap Regulations (2026)
Everything a Nebraska restaurant or commercial kitchen needs to know about grease trap requirements: who regulates it, how often you must clean, what permits and registration you need, what records to keep, and what violations actually cost. Citations link to the official source so you can verify every claim — and show your inspector you did.
Nebraska Requirements at a Glance
| Cleaning frequency | No statewide interval — the state pretreatment program (Title 119) targets significant industrial users (≥25,000 gpd), not typical restaurants, so grease trap schedules come entirely from municipal sewer-use ordinances. |
| State regulator | Nebraska Department of Water, Energy and Environmental Management (DWEE) |
| Governing regulation | Nebraska Title 119 (NPDES permitting / pretreatment). Grease trap waste falls under the pretreatment program only if industrial-user thresholds are met; otherwise it's governed by local sewer-use ordinances |
Who Regulates Grease Traps in Nebraska
At the state level, Nebraska Department of Water, Energy and Environmental Management (DWEE) (program page) oversees FOG (fats, oils, and grease) discharge; the governing rule is Nebraska Title 119 (NPDES permitting / pretreatment). Grease trap waste falls under the pretreatment program only if industrial-user thresholds are met; otherwise it's governed by local sewer-use ordinances. Day-to-day enforcement — inspections, cleaning intervals, fines — usually happens through your city or county sewer utility's pretreatment program, which can set stricter rules than the state.
City Programs in Nebraska
Cities run their own FOG programs and often set stricter rules than the state:
Omaha
- Program: City of Omaha grease interceptor program (Building Services / sewers)
- Ordinance: Omaha Municipal Code Ch. 49 §§49-1130 et seq. (grease traps); Ch. 31 (sewers)
- Permit: Plumbing permit required for interceptor installation; code distinguishes outdoor interceptors (>50 gpm) from indoor traps (≤50 gpm)
Lincoln
- Program: Lincoln wastewater discharge program (Lincoln-Lancaster County Health Dept. + Public Works)
- Ordinance: Lincoln Municipal Code §17.58.080
- Permit: Plans must be submitted to the Health Director for review before building, converting, or remodeling a food establishment
Worth Knowing in Nebraska
Nebraska has no statewide FOG-specific grease trap program — it's handled locally by municipal POTWs under NPDES authority delegated to the state. Neither Omaha nor Lincoln publishes a detailed cleaning-frequency, hauler-license, or manifest requirement online, so the practical rule is: confirm directly with your local sewer authority before relying on a schedule.
Frequently Asked Questions
How often must grease traps be cleaned in Nebraska?
No statewide interval — the state pretreatment program (Title 119) targets significant industrial users (≥25,000 gpd), not typical restaurants, so grease trap schedules come entirely from municipal sewer-use ordinances. Your city's FOG program may require more frequent service — and regardless of the legal interval, clean before fats, oils, and grease reach 25% of trap capacity.
Do I need a permit for a grease trap in Nebraska?
In most Nebraska cities, yes — food service establishments must register with, or get a permit from, the local FOG / pretreatment program before discharging grease trap waste to the sewer. The exact permit and registration requirements vary by city; the major-city programs are listed above, and your local sewer authority has the specifics for your address.
