The right yard drainage solution depends on how the water reaches the problem area and where it can go next. Visible surface runoff and puddles are usually handled with grading, swales, catch basins, channel drains or roof-water controls. Water moving through saturated soil may call for a French drain or curtain drain. A dry well is primarily an infiltration destination, while a pop-up emitter is an outlet component. Many properties need more than one of these parts working together.
Before comparing products or project prices, identify where the water appears, where it comes from, whether it is moving on the surface or through the soil, and whether there is a safe destination for it. If the source is still unclear, start with Yard Drainage Problems: Causes, Signs and Solutions or the deeper How to Fix Yard Drainage Problems diagnostic guide.
Start by matching the function, not the product name
Drainage systems are easier to compare when you separate the jobs they perform. A catch basin, French drain and dry well are not interchangeable just because all three involve buried drainage components.
| Function | What the job means | Common examples |
|---|---|---|
| Surface reshaping | Change the grade or create a shallow path so runoff moves away from a problem area instead of collecting there. | Regrading, swale |
| Collection | Capture visible surface water where it concentrates at a point or along an edge. | Catch basin, channel drain |
| Interception | Catch water before it reaches the area you are trying to protect. | Curtain drain; some French-drain layouts |
| Conveyance | Move collected water through a stable path toward a destination. | Solid drain pipe, swale |
| Infiltration / discharge | Give the water a safe place to soak in or be released after it has been collected and moved. | Dry well, approved outlet, pop-up emitter |
Use what the water is doing to narrow the options
| What you are seeing | Water behavior | Options to compare first | Main check before choosing |
|---|---|---|---|
| A defined low spot holds visible water after rain | Surface | Grading/regrading; catch basin | Can runoff reach the low spot and then reach a suitable outlet? |
| Runoff sheets across a broad slope or side yard | Surface | Swale; grading/regrading | Is there enough room and fall to move water without shifting the problem? |
| Water crosses a driveway, patio or other hardscape edge | Surface | Channel or trench drain | Where will the connected pipe discharge? |
| A downspout creates a recurring wet area | Roof runoff | Downspout drainage system; possible dry well or emitter at the destination | Where can concentrated roof water go safely? |
| A long strip stays soggy or seepage appears from a slope | Subsurface | French drain; curtain drain | Where is the water moving through the soil, and is a lower outlet available? |
| Collected water has no practical surface outlet | Destination problem | Dry well where infiltration is suitable | Do soil, groundwater, space and local requirements support infiltration? |
| A buried drain line needs to release water at the lawn surface | Outlet component | Pop-up emitter | Can the receiving area accept the flow without ponding or erosion? |
Compare the main yard drainage solutions
French drains
- What it does
- Use a gravel-filled trench and perforated pipe to intercept water moving through saturated soil and carry that water toward an outlet.
- Best fit
- Soggy soil, subsurface seepage, or a wet strip where water is moving through the soil rather than simply sitting on top of it.
- Watch for
- A French drain still needs a workable outlet. It is a poor first choice for an isolated surface puddle that is not entering the soil quickly.
Catch basins
- What it does
- Collect visible surface water through a grate at a defined low point and send it into connected drain pipe.
- Best fit
- A recurring puddle or concentrated runoff that reliably reaches one collection point.
- Watch for
- The basin only collects what reaches it. The pipe still needs a safe destination, and the grate/sump must remain accessible for debris removal.
Dry wells
- What it does
- Receive collected water, temporarily store it below grade, and allow it to infiltrate into surrounding soil.
- Best fit
- Sites where on-property infiltration is appropriate and soil, groundwater, available space and local requirements support it.
- Watch for
- A dry well is a destination, not the collection system itself. Slow-draining or already saturated conditions can make infiltration unsuitable, and some designs are regulated.
Yard grading and regrading
- What it does
- Reshape the ground surface so runoff moves away from low spots or vulnerable areas along a controlled path.
- Best fit
- Wrong-way slope, shallow depressions, or runoff that is being directed toward the house or another problem area.
- Watch for
- Grading changes where water goes; it should not create a new problem for a neighbor, street or structure. It also does not fix persistent subsurface seepage by itself.
Drainage swales
- What it does
- Use a shallow graded channel to intercept and convey broad surface runoff across the landscape.
- Best fit
- Water that travels across a wide area, especially where there is room for a visible surface drainage path.
- Watch for
- A swale needs enough space, stable grading and a suitable destination. Vegetation, sediment and erosion conditions affect long-term performance.
Channel and trench drains
- What it does
- Collect surface water along a line through a grated channel and connect it to downstream drain pipe.
- Best fit
- Driveways, patios, walkways and other hardscapes where runoff crosses a predictable edge or threshold.
- Watch for
- The channel still needs downstream conveyance and an outlet. Retrofitting through finished hardscape can increase disruption, and the grate must stay clear.
Downspout drainage systems
- What it does
- Manage concentrated roof runoff by carrying water away from the downspout discharge point toward a suitable destination.
- Best fit
- Wet areas that consistently begin where roof water leaves a downspout or where several roof areas concentrate runoff.
- Watch for
- Moving roof water farther away is only useful if the new endpoint can receive it safely. Do not assume a street, storm drain, neighboring property or public system is an allowed outlet.
Pop-up drainage emitters
- What it does
- Provide a downstream release point for water already collected and conveyed through buried pipe; the cap opens as flow builds and closes after flow drops.
- Best fit
- The end of a buried gravity line where water can be released onto a receiving area without creating a new drainage problem.
- Watch for
- An emitter is not a collection system. It needs a suitable receiving area, compatible elevations and routine debris checks so the outlet does not become blocked.
Curtain drains
- What it does
- Intercept subsurface water moving laterally through saturated soil, often by placing a drain across the path of seepage before it reaches the problem area.
- Best fit
- Uphill seepage, hillside moisture or subsurface water that can be intercepted before reaching a yard area or structure-adjacent zone.
- Watch for
- Depth, soil layers, slope and outlet elevation matter. A curtain drain is not a generic replacement for surface grading or point collection.
The comparisons that resolve the most common choices
French drain vs. catch basin
Start with where the water is: a French drain targets subsurface water in saturated soil; a catch basin targets visible surface water at a collection point. Compare French drains and catch basins in detail.
French drain vs. dry well
These often do different jobs rather than competing for the same job. A French drain intercepts and moves subsurface water; a dry well provides an infiltration destination where conditions allow. Compare French drains and dry wells in detail.
French drain vs. swale
A swale manages broad surface runoff in a visible graded path. A French drain works below grade on water moving through saturated soil. Compare French drains and swales in detail.
Yard grading vs. French drain
Grading corrects surface shape and runoff direction. A French drain addresses subsurface water. The water type and path matter more than which option sounds more permanent. Compare yard grading and French drains in detail.
When a combined system makes more sense
Some yards need one component to collect or intercept water and another to move or release it. That is not necessarily overbuilding; it can be the result of keeping each drainage function separate.
- A catch basin or channel drain collects surface water, then solid pipe conveys it to a suitable outlet.
- A downspout system carries roof water to a dry well when infiltration is appropriate, or to another approved release point.
- Grading or a swale routes broad runoff toward a controlled collection point instead of allowing water to spread across the yard.
- A French drain or curtain drain intercepts subsurface water, then a solid outlet section carries that water to its final destination.
- A pop-up emitter may serve as the terminal release point for a buried line when the receiving area and local conditions make surface discharge appropriate.
The key is to design the sequence from source to collection or interception, through conveyance, and finally to infiltration or discharge. Installing a drain without confirming the endpoint can simply move the problem.
What to check before choosing
- Watch at least one rainfall event if it is safe to do so. Note where water starts, the path it follows, where it pools and how long the area stays wet afterward.
- Separate surface runoff from subsurface saturation or seepage. Visible flow on top of the ground and persistent wet soil may need different tools.
- Trace roof, driveway, patio and neighboring upslope runoff before adding a buried drain. Concentrated sources can overwhelm an otherwise reasonable system.
- Confirm whether gravity can move water to a lower destination. If the property has no usable outlet, infiltration or a professionally designed pumped solution may become part of the discussion.
- If infiltration is being considered, evaluate soil drainage, groundwater conditions, available area and local requirements rather than assuming a dry well will work everywhere.
Before any digging, use the national 811 before-you-dig service or your state 811 center to have buried utilities located. Significant excavation, recurrent flooding, water threatening the house, unclear discharge legality, or a design that depends on capacity and elevation calculations warrants an onsite evaluation by an appropriate drainage, grading or excavation professional.
Local stormwater rules can affect where water may be discharged or infiltrated. Grading and drainage changes should not intentionally concentrate runoff onto neighboring property, and a national guide cannot determine what a municipality, subdivision, easement or watershed authority allows on a specific lot.

If you already recognize the system you are considering, review the matching solution card above. If you do not, document one storm first—source, path, pooling location, time to drain, and any possible outlet. Those observations will make the comparison more useful and give a contractor or site evaluator better information to work with.
