Yard Drainage Cost by System Type
Dated national figures compared by system type and unit — with methodology and limitations, and no invented Huntsville average.
The figures below are published national ranges drawn from cost guides, compared side by side so you can see how different yard drainage systems tend to price out. They are not Huntsville quotes and not a local average. A third-party provider confirms real pricing for a specific property; a national range only tells you the shape of the problem.
Per-system ranges, by project
These are whole-project figures — what a published guide reports for a typical installation of that system, before the site-specific details that push a job up or down.
| System | Published national range | Source |
|---|---|---|
| Overall yard drainage installation (broad average) | $2,147–$7,169 [source] | Angi |
| Subsurface yard drainage (e.g. French drain systems) | $1,200–$8,000 [source] | HomeGuide |
| Dry well | $50–$700 for many gravel or plastic systems; concrete up to $3,000+ [source] | HomeGuide |
| Yard regrading / leveling | $500–$5,000 [source] | HomeGuide |
These figures overlap and are not additive. Each row describes a different system or scope, so do not combine them into a project total. The system type narrows the relevant range; the property-specific design determines where a real quote falls.
Per-unit ranges
Linear-foot and per-unit figures are often more useful for reasoning about a specific layout, because they scale with the length of pipe or the number of collection points.
| Unit | Published national range | Source |
|---|---|---|
| Most drainage systems, per linear foot | $10–$50 per linear foot [source] | Angi |
| Subsurface drainage, per linear foot | $8–$15 per linear foot [source] | HomeGuide |
| Buried / underground downspout drainage, per downspout | $150–$350 per downspout [source] | HomeGuide |
| Site preparation | $300–$1,000 [source] | Angi |
The two per-linear-foot figures differ because they describe different scopes: the $10–$50 range spans most drainage system types broadly, while the tighter $8–$15 figure is specific to subsurface work.[source][source]
Timelines
Duration is part of cost. Published figures describe simple installs at around one to two days, with complex runs stretching up to about two weeks.[source] A longer job usually means more length, harder digging, or more obstacles — the same drivers that move the dollar figures.
Methodology and limitations
What national guides include
Published guides like these blend labor, materials, and typical site conditions across many regions into a single range. They generally fold in common line items — trenching, pipe and aggregate, basic restoration, and some site preparation — but the exact inclusions vary by guide and by system. Treat the numbers as directional, not itemized.
Why no Huntsville average is published here
This site does not publish a Huntsville yard drainage average, because no verified local figure exists in its evidence ledger. Manufacturing one from national data — or from a handful of jobs — would be a guess dressed up as a fact. The honest statement is that pricing for a real Huntsville property is confirmed by a third-party provider against the actual layout, soil, outlet distance, and restoration involved.
What moves a real number
- Total length of pipe or trench, and the depth required
- Distance and elevation drop to a lawful, workable outlet
- Obstacles: roots, hardscape crossings, utilities, fences
- Soil that digs hard or drains poorly
- Restoration of sod, beds, and surfaces afterward
