Not sure where your sump pump should drain in Omaha? You want to protect your foundation, avoid neighbor issues, and follow city rules. This quick guide walks you through legal discharge options, what to avoid, simple design tips, and who to call for permits so you can make the right choice for your property. Let’s dive in.
Omaha rules at a glance
- Do not discharge to the sanitary sewer. Omaha’s plumbing code prohibits sending subsoil or foundation water into the sanitary system, including floor drains or sinks. See the local code reference for details in the section on subsoil drains and sump pumps. Review the Omaha plumbing code reference.
- Prevent nuisance runoff. Your discharge cannot flow across sidewalks, driveways, or onto neighboring property. If that would happen at the surface, the code directs you to pipe the discharge to a storm sewer. See the code explanation.
- Construction dewatering is different. Large pumping for construction requires a City permit and water-quality controls. Check the Construction Dewatering Discharge Permit.
Legal places to discharge your sump pump
Yard or on-site infiltration
Routing the outlet into your own yard is common when it will not create nuisance flow or property damage. Direct water away from the house so it can soak in, or use an infiltration feature like a dry well or rain garden sized for your soil and lot. Model plumbing guidance supports these methods when properly designed. See practical guidance.
Storm sewer connection
If a storm sewer is available, you can pipe the discharge to it with proper materials and installation. This is preferred when surface discharge would reach sidewalks or adjacent lots. The code expects foundation drainage to reach a storm facility or acceptable outlet. Review the local code reference.
Curb or street gutter by permission
When no storm line is available and you cannot avoid nuisance flow, Omaha Public Works may allow routing to the street gutter with specific conditions. Always contact the City before planning this option. Start with the City’s permitting resources.
What you cannot do in Omaha
- Never discharge to the sanitary sewer. Do not route your sump to a floor drain, sink, toilet, or sewer cleanout. It is an illegal connection under Omaha’s plumbing code. See the code reference.
- Do not create nuisance runoff. Avoid flows over sidewalks, driveways, or neighboring property. If needed, tie into a storm sewer instead. Review the ordinance language.
Keep your outlet away from the foundation
Omaha requires your sump discharge to terminate at least 3 feet from the building foundation to reduce recirculation and water intrusion. See the local code reference.
Design tips to prevent backups and ice
- Install a check valve. A full-flow check valve in the discharge line helps stop water from flowing back into the sump. Code guidance here.
- Use proper materials. Rigid piping through the wall and durable exterior pipe, plus a splash pad, help manage erosion and wear. See model-code best practices.
- Plan for winter. Long above-ground runs can freeze and create icy hazards on sidewalks or streets. Consider a buried line that slopes away from the house, short above-ground sections, or an infiltration feature. Review local code considerations.
Permits and who to call in Omaha
- Plumbing permits and inspections. Some sump discharge work requires permits and sign-off by a licensed plumber under Omaha’s Chapter 49. Confirm your scope with the City before you start. Visit Permits & Inspections resources.
- Public Works and stormwater questions. For construction dewatering, routing to storm inlets, or curb-gutter questions, start with Public Works. See the dewatering permit page.
- Lot grading and HOA rules. Your plat, drainage easements, or HOA may add restrictions. Check these before finalizing your plan. Read lot grading guidance.
Simple planning checklist
- Map where water goes today and note any sidewalk or neighbor impacts.
- Pick a legal outlet: yard infiltration, storm sewer, or curb by permission if no storm is accessible.
- Keep the outlet 3 feet or more from the foundation and add a splash block.
- Add a check valve and choose durable, cold-weather-friendly materials.
- If burying pipe or tying into storm, confirm permit needs with the City and hire a licensed pro.
When to hire a professional
Bring in a licensed plumber or sewer layer if you plan to bury a permanent line, core through a foundation wall, connect to a storm inlet, or need permits and inspections. A civil or landscape pro can help size dry wells or rain gardens and set proper slopes when yards are flat or soils drain poorly.

Is it legal to run my sump line to the street gutter in Omaha?
