Exterior Drains and Downspouts
Drainage begins at the gutters. When they overflow, or downspouts end right beside the wall, a season of rain soaks the soil where the basement is most exposed. Extensions should drop it well out in the yard, pointed at neither the house nor the lot next door, and never into a floor drain or sewer line. No City of Omaha downspout program was found.
Grading comes next. Soil should fall away from the foundation on every side, window wells need a drain under clean gravel, and the curbside storm inlet works better with leaves kept off its grate.
Below ground, a footing drain at the base of the foundation takes water to an outlet or a sump. A French drain, a gravel trench around perforated pipe, intercepts water crossing a yard where the lot has a lower spot to empty into.
The ground shapes all of this. USGS maps wind-blown loess on the higher ground between the area's creeks, clayey glacial till mostly buried beneath it and alluvium in the valleys; till can hold water against a wall, and alluvium can carry groundwater toward a foundation.
Where Basement Drainage Fits
If water still finds the floor, interior drain tile catches it inside: a channel opened in the slab beside the problem walls, perforated pipe bedded in gravel and pitched toward a sump. The yard stays untouched, which often suits older poured, block, brick or stone walls.
- Overflowing gutters. Cleaned, resized or re-pitched so water reaches the downspouts.
- Short downspouts. Extended to release water out in the yard, clear of the neighbors.
- A backward slope. Soil rebuilt so the ground drops away from the walls.
- Window wells that fill. A drain at the bottom, so snowmelt can't pool against the glass.
- Wet floor edges. Interior drain tile that empties into a sump.
Typical Price Ranges
| Cost row | Figure | Source (year) |
|---|---|---|
| Typical basement waterproofing project | about $3,000 to $10,000 (average about $5,000) | Fixr national (2026) |
| Interior perimeter drain, per linear foot | $40 to $120 | Fixr national (2026) |
| Sump pump installation | $600 to $2,500 | Fixr national (2026) |
| Epoxy crack injection, per crack | $250 to $1,000 | Fixr national (2026) |
| Waterproof paint or sealant, per sq ft | $1 to $8 | Fixr national (2026) |
All five rows are 2026 national figures; nobody publishes drainage prices for Nebraska or Omaha alone. Tile is priced by the foot, so one wall costs far less than the full perimeter. Backwater valves, lateral repairs and drain connections are plumbing or sewer-layer jobs priced on their own. More detail sits in the cost guide and the cost calculator.
The Typical Job, in Order
- Notes from the last storm. Where water pooled outside, and where it showed up inside.
- Outside first. Contractors usually check gutters, downspout ends and slope before the floor.
- A written plan. Which walls, feet of pipe, where every outlet ends, materials and one total.
- Permits. At an Omaha address, excavation or foundation work may require a City building permit, and sewer connections a permit pulled by an Omaha-licensed plumber or sewer layer. Which apply is the contractor's question for Permits & Inspections, (402) 444-5350; towns keep their own offices.
- The next soaking rain. It shows whether the changes work.
Less Hassle, Clearer Answers
Your description reaches one independent local contractor, who contacts you; it costs you nothing and brings you nothing. A flat advertising fee from that contractor may support this site, which digs nothing.
Before you sign, ask which permits apply and who pulls them. Keep the down payment reasonable, ask for a lien waiver each time you pay, skip cash and hold the balance until the work is finished. The Nebraska Attorney General's Consumer Protection Division, (800) 727-6432, hears complaints.
Frequently Asked Questions
Should the outside be fixed before paying for drain tile?
Often, yes. Clear gutters, longer extensions and soil that slopes away cost far less than pipe under the floor. If water still gets in after a year of storms and thaws, ask how much tile each wet wall needs.
Water came up through the floor drain. Is that a drainage problem?
Usually it is the sewer, not seepage, and drain tile won't stop it. After the Sept 30 to Oct 1, 2026 storm, which Omaha Public Works called "a 100-year event", homeowners reported basement backups (WOWT). Omaha addresses report backups at 402-444-5332, with Public Works at 402-444-5220; each nearby town has its own sewer office.
Who looks after the pipe from the house to the street?
Ask your city which part is yours. A clog or break in that private line is permit work for a licensed plumber or sewer layer; in Omaha, an Omaha-licensed plumber or sewer layer. A licensed plumber can also say whether a backwater valve suits your home.
What is the City's CSO Program doing?
In parts of older, eastern Omaha, one set of pipes carries both stormwater and wastewater. The City's CSO Program, begun in 2009 and due to wrap up in 2037, aims to capture or treat 85% of that combined flow in an average year. EPA expects its Saddle Creek basin to cut overflow events into Little Papillion Creek from 58 a year to 5. It targets overflows, not every basement backup.
