2026 scope and estimate guide
Augusta Yard Drainage Cost Guide
A buried downspout route starts at $150 to $350 per downspout, while a shallow exterior French drain starts at $10 to $35 per linear foot in national cost guides. The useful estimate begins after the water source, soil, elevations, outlet, and restoration are defined.
Editorial review: July 19, 2026. Cost figures and local guidance were rechecked on that date.
Augusta Yard Drainage Help is an independent educational and lead-generation website. It does not perform drainage work directly. Requests may be shared with a local outdoor drainage provider when a fit is available.
Quick answer
HomeGuide publishes $150 to $350 per downspout for a buried roof-runoff system and $10 to $35 per linear foot for a shallow exterior French drain. Length is only one factor: every quote also carries site-specific costs for access, soil, basins, utility conflicts, the outlet, and putting the yard back together.
Factors that shape the scope
HomeGuide places around-the-house yard and curtain-drain systems near $1,000 to $4,000 and gives a broader $500 to $8,800 exterior-project span. Modernize’s published range reaches $10 to $65 for each foot on difficult exterior French-drain work; LawnStarter reports those same endpoints. Modernize also shows about $1,000 to $6,500 for 100 feet. The route through the yard determines where a project lands inside those national planning ranges.
- Length, width, and depth determine trench volume, pipe, fabric, aggregate, and labor
- A narrow gate or hardscape crossing can replace machine excavation with slower hand work
- Catch basins, cleanouts, and downspout tie-ins add fixed pieces beyond the trench price
- A protected gravity outlet has a different scope from a pump; Modernize lists $500 to $4,000 for a sump system, while Lawn Love lists a $625 to $2,625 French-drain add-on
- Sod, seed, planting beds, walkways, patios, and removed-soil handling belong in the written restoration scope

Per-foot pricing meets fixed project costs
A per-foot number covers work that grows with trench length. Basin hardware, mobilization, aggregate delivery, a pump, outlet protection, utility rerouting, and surface repair behave more like fixed charges. A three-to-fivefold quote spread can appear when bidders price different systems for the same wet-yard symptom. For example, a hypothetical $2,600 proposal for two buried downspout routes and a basin cannot be compared directly with a $10,400 proposal that adds a long subsurface collector, a pump, outlet construction, and full sod restoration. The arithmetic is four times higher because the proposed work is different, not because one price per foot is automatically wrong.
Which soil is under your yard changes which fix earns its cost
Augusta sits at Georgia’s fall line between the Piedmont and Upper Coastal Plain. The New Georgia Encyclopedia describes clay soils north of that transition and predominantly sandy soils to the south. University of Georgia Extension reports that Georgia Piedmont sandy-clay-loam soils average moderate infiltration and hold water better than sandier soils. A clay-side yard may need collection plus a dependable route out. A sandy surface may infiltrate quickly, yet it can overlie a hardpan or a tighter sandy-clay layer; University of Georgia guidance says water remaining in a 12-to-15-inch test hole after 12 hours may indicate hardpan, and a U.S. Geological Survey study near Augusta documents sand interbedded with sandy clay and low-permeability clay beds. Diagnose the actual profile and water source before paying for a trench.

Compare complete scopes, not totals alone
Ask each bidder to name the water being collected, pipe type, measured fall, discharge point, maintenance access, and restoration. A $10-to-$35-per-foot shallow collector, a $30-to-$150-per-foot trench or channel drain, and a $150-to-$350 buried downspout system solve different flow patterns. Georgia’s Secretary of State lists grading and landscape and irrigation among traditional specialty work that does not require a residential or general contractor license, while still requiring compliance with applicable codes and ordinances. Ask what credential, permit, or local approval applies to the exact work, especially if a proposal reaches a public system or another regulated trade.

Line items worth separating
Put the $10 to $35 or $10 to $65 per-foot trench allowance on its own line, then separate basins, solid downspout pipe, cleanouts, pump equipment, aggregate delivery, removed soil, outlet protection, and restoration. HomeGuide lists trench or channel drains at $30 to $150 per linear foot. If gravity cannot reach a suitable destination, compare the pump allowance against Modernize’s $500 to $4,000 system range or Lawn Love’s $625 to $2,625 add-on range. This format shows which quote includes the working outlet and which one stops at buried pipe.

Why photos are useful but limited
Photos can show pooling, roof-runoff concentration, gate width, and visible hardscape. They cannot establish trench depth, buried conflicts, soil layers, or enough fall to a lawful outlet. A photograph may support a first conversation about a $150-to-$350 downspout route or a $10-to-$35-per-foot French drain, but a final quote should follow onsite measurements and an outlet decision.
Digging and discharge planning belong in the price
Georgia law requires an excavator using mechanized equipment to request a utility locate before excavation. Georgia 811 says to submit a ticket at least three business days before digging and to check every utility response before work begins. The quote should identify who submits and checks that ticket. Standard utility members mark public lines only; irrigation, septic, landscape lighting, invisible fences, and other private facilities require a private locator. Conflicts can lengthen the route or force hand excavation. Augusta Engineering Department’s stormwater program manages public stormwater assets, and the county code gives the department authority over private systems that discharge to the county system. Confirm any proposed public-system connection or changed discharge with Augusta before treating that outlet as part of the price.

DIY material prices do not guarantee a cheaper working drain
HomeGuide estimates do-it-yourself drainage materials and tools at $4 to $8 per linear foot. Lawn Love’s itemized example totals about $528 for a 25-foot French drain with one catch basin, or roughly $21 per foot. Tool rental, delivery, extra aggregate, private-line locating, removed soil, and lawn repair can erase the apparent labor savings. A trench that misses its slope or has no workable outlet can hold water or send it the wrong direction, so doing the digging yourself does not reliably save money.

Interior pricing is a boundary, not a yard allowance
For comparison only, HomeGuide’s indoor category runs from $40 to $85 for each linear foot, with complete installations listed between $4,000 and $17,000. That basement work falls outside this site’s outdoor-yard scope. Do not use it to inflate or benchmark an Augusta lawn-drainage quote.

Common questions
What does a French drain cost in Augusta?
HomeGuide publishes $10 to $35 per linear foot for a shallow exterior French drain and $500 to $8,800 across broader exterior yard or curtain-drain projects. These are national planning ranges checked in 2026, not Augusta averages or a local quote.
Why can Augusta yard-drainage quotes vary so much?
A quote combines length-based trench work with fixed costs for basins, delivery, access, utilities, an outlet, a pump when needed, and restoration. A three-to-fivefold spread can reflect different proposed systems, so compare the water source, measurements, outlet, materials, and restoration line by line.
Is a DIY French drain cheaper?
Not reliably. HomeGuide lists $4 to $8 per linear foot for do-it-yourself tools and materials, while Lawn Love itemizes about $528 for a 25-foot example, or roughly $21 per foot. Rentals, extra materials, locating, disposal, restoration, and correcting a mis-sloped trench can consume the apparent savings.
Do I need Georgia 811 before digging a French drain?
Yes for mechanized excavation: Georgia law requires the excavator to request a locate before digging. Georgia 811 also encourages notification for smaller hand-dug projects. Standard locates cover member-owned public utilities, not private irrigation, septic, landscape-lighting, or similar lines, so the person doing the work may also need a private locator.
What is the cheapest drainage fix to check first?
When pooling starts at a downspout, check the gutter and above-ground extension first. HomeGuide publishes $150 to $350 per downspout for a buried system that includes a catch basin, extension, trenching, drain pipe, and bubbler system. The outlet still needs enough fall and an acceptable destination.
Can I get a French drain price from a photo?
A photo can support an initial discussion, but a firm scope usually depends on measurements, elevations, access, soil, outlet conditions, and restoration. Be cautious with a final number that skips those details.
