Perforated PVC pipe typically costs $1.50-$8 per linear foot, depending on diameter, wall strength, hole pattern, and where it is purchased. A 100-foot drainage run may cost $300-$1,500 for pipe and common fittings, while trenching and installation can raise the project total substantially.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 4-inch perforated PVC pipe | $1.50 per ft | $3.25 per ft | $6 per ft | Price varies by wall rating and length |
| 6-inch perforated PVC pipe | $4 per ft | $7 per ft | $12 per ft | Heavier pipe and fewer stock options |
| Pipe and fittings for 100 ft | $200 | $550 | $1,500 | Before excavation and labor |
| Installed drainage run | $1,000 | $3,000 | $7,500 | Site access and trench depth affect total |
What 4-Inch Perforated PVC Pipe Usually Costs
For residential drainage, 4-inch perforated PVC generally runs $1.50-$6 per linear foot, with a common midrange price of about $2.50-$4 per foot. A 10-foot length often retails for roughly $20-$60. Prices depend on whether the pipe is thin-wall drainage grade, sewer-and-drain grade, or a heavier specification intended for greater loading.
A 100-foot materials order commonly totals $250-$700 when it includes basic couplers, an end cap, and a few changes in direction. Heavier-wall pipe, numerous fittings, or a specialty hole pattern can push the same order toward $1,000 or more. Bulk contractor pricing may be lower than buying short lengths at a home-improvement store.
For a typical 4-inch residential drain, budget about $300-$700 for pipe and basic fittings before excavation. This estimate assumes a straight, 100-foot run using standard pipe, ordinary access, and no outlet structure or pump.
Assumptions: U.S. retail and supply-house pricing, standard residential drainage products, materials only unless noted.
How Pipe, Fittings, and Trenching Shape the Quote
A pipe quote may cover only the pipe itself. A complete drainage estimate can also include couplers, elbows, tees, cleanouts, filter fabric, gravel, excavation, bedding, backfill, and removal of excess soil. Ask whether the contractor’s per-foot rate includes those items, since they can change the total substantially.
| Quote component | Low | Average | High | Typical basis |
|---|---|---|---|---|
| 4-inch perforated pipe | $1.50 per ft | $3.25 per ft | $6 per ft | Standard drainage grade |
| Fittings and cleanouts | $25 | $100 | $350 | Small residential run |
| Gravel and filter fabric | $1 per ft | $4 per ft | $10 per ft | Varies with trench width and depth |
| Excavation and installation labor | $5 per ft | $18 per ft | $45 per ft | Accessible soil to difficult digging |
| Delivery and soil disposal | $50 | $250 | $800 | Distance, load, and disposal volume |
Labor prices often reflect the full trench-and-pipe task, not simply joining pipe. A crew may charge $50-$125 per hour, or quote $5-$45 per linear foot for excavation and placement. A 20-hour job at $75 per hour, for example, adds $1,500 before materials or equipment charges.
Check whether gravel, fabric, backfill, and hauling are included before comparing per-foot installation bids. Two quotes with the same pipe rate can differ by hundreds of dollars if one includes these tasks and the other lists them separately.
How Diameter, Hole Pattern, and Wall Rating Change Price
Diameter is a major price driver. Four-inch pipe is common for yard drains and foundation drainage; 6-inch pipe often costs $4-$12 per foot and is used when the design calls for more capacity or a larger collector. Larger sizes may require bigger fittings, a wider trench, and more gravel, so the material premium is not the only added expense.
Wall construction matters as much as size. Thin-wall drainage pipe is often the least expensive, while sewer-and-drain or stronger-wall products cost more. Schedule 40 PVC is generally a heavier, higher-cost choice and may be priced around $4-$10 or more per foot when perforated. The correct type depends on project design and expected loading; a drive or roadway may require a specified pipe class rather than a general-purpose yard drain product.
Hole placement and orientation also affect selection. Some products have holes around the circumference; others have rows intended to face down or toward the sides. Factory-perforated pipe usually costs less than having holes cut into solid pipe, but a custom pattern or nonstandard size can raise the unit price. Verify the pipe’s drainage rating and installation instructions instead of choosing solely by diameter.
A jump from 4-inch to 6-inch pipe can add $2-$6 per foot before the wider trench and larger fittings are counted. For 100 feet, that diameter change alone may add $200-$600 in pipe materials.
Assumptions: Common 4- and 6-inch residential products; specialty commercial specifications may price higher.
Where Buyers Can Cut Perforated PVC Drainage Costs
Keep the run as direct as the drainage plan allows. Each extra bend or branch needs fittings and may add labor, while unnecessary extensions increase pipe, gravel, and excavation quantities. Confirm the planned route and outlet location before ordering materials to avoid paying for a second mobilization or a replacement fitting order.
Choose the pipe grade specified for the site rather than automatically buying the thickest product. Conversely, do not substitute a lighter pipe where the design calls for stronger wall construction or a particular rating. Getting the correct specification from the installer or project plan can prevent both overspending and premature failure.
Compare complete quotes using the same length, diameter, pipe class, trench depth, and included materials. Ask contractors to separate pipe, fittings, excavation, gravel, fabric, disposal, and restoration. If the site is accessible, homeowners may be able to handle permitted, nontechnical preparation such as clearing brush, but utility locating and safe excavation still need to be addressed.
Reducing unnecessary trench length and matching pipe grade to the actual loading are the most direct ways to control the materials budget. Do not reduce pipe size or omit filter fabric and gravel where the design requires them; correcting a failed drain can cost more than the original savings.
What Installation Labor Adds to a 100-Foot Drain
Installing a 100-foot run can take a small crew roughly one to three days, depending on trench depth, soil, access, connections, and restoration. Straightforward work in open, workable ground may cost $1,000-$2,500 for labor and basic excavation. Deep trenches, hand digging, roots, concrete removal, or restricted equipment access can bring labor and equipment charges to $3,000-$6,000 or more.
Contractors may price installation by the foot, by the day, or as a complete project. A basic trench-and-place rate might be $10-$25 per foot, while deeper or difficult work can exceed $40 per foot. A minimum service charge or equipment mobilization fee may apply to a short run, making small jobs more expensive per foot than longer projects.
Ask whether the labor quote includes excavation, pipe bedding, connections, backfill, compaction, and surface repair. Lawn restoration, paving, steps, or landscaping can be billed separately. A low base rate may exclude soil hauling and the final grading needed to leave the area usable.
For a 100-foot installation, labor and excavation commonly exceed the pipe cost. A materials-only comparison will not predict the final project budget unless the homeowner plans to do the digging and restoration.
How Perforated PVC Compares With Corrugated Drain Pipe
Flexible corrugated plastic drain pipe often costs about $0.50-$2 per foot for basic perforated products, less than rigid PVC. Sock-covered or heavier corrugated options may cost $1-$4 per foot. Its lower price and flexibility can suit uncomplicated yard drainage, but it may be harder to clean, can deform under loads, and may need careful bedding to maintain slope.
Rigid perforated PVC generally costs more but holds its shape and can be easier to rod or inspect when the system is laid out with suitable cleanouts. For a 100-foot run, the pipe-only difference between basic corrugated pipe at $1 per foot and PVC at $3.25 per foot is about $225. Fittings, installation method, design requirements, and expected vehicle loading may narrow or widen the overall difference.
Solid PVC is not a direct substitute for perforated pipe along the collection portion of a drain because it does not admit surrounding water. It can be appropriate for carrying collected water from the perforated section to an outlet. A system may therefore use both types, with solid pipe where water is being conveyed rather than collected.
Compare the installed system and intended use, not just the lowest price per foot. A drainage plan or local specification may require a particular material, diameter, or strength class.
Three 4-Inch Drainage Runs and Their Estimated Prices
A simple 50-foot garden drain using standard 4-inch pipe, a few fittings, and shallow excavation may cost $125-$350 for materials and $700-$1,800 installed. That assumes easy access, no pavement removal, modest gravel use, and a nearby outlet.
A 100-foot foundation drain with 4-inch sewer-and-drain pipe, filter fabric, gravel, cleanouts, and ordinary excavation may run $450-$1,000 for materials. With labor, hauling, and backfill, a typical project estimate could be $2,000-$5,000. Basement waterproofing work, deeper excavation, or substantial restoration can increase the total.
A 100-foot collector using 6-inch perforated pipe for a larger drainage area may require $600-$1,500 in pipe, fittings, and supporting materials. Installation might bring the project to $3,000-$7,500 if the trench is deeper, needs more gravel, or requires equipment and significant soil disposal.
| Scenario | Pipe and materials | Labor and site work | Estimated total |
|---|---|---|---|
| 50-ft shallow yard drain | $125-$350 | $575-$1,450 | $700-$1,800 |
| 100-ft foundation drain | $450-$1,000 | $1,550-$4,000 | $2,000-$5,000 |
| 100-ft 6-inch collector | $600-$1,500 | $2,400-$6,000 | $3,000-$7,500 |
Assumptions: Typical U.S. residential work, accessible route, no major utility conflicts, and no unusually costly paving or landscape restoration.
When Delivery, Disposal, and Trench Access Raise the Price
Long pipe lengths can be awkward to transport, and supply houses may charge delivery fees of $50-$250 for local orders. Remote deliveries, special handling, or a truck that must make multiple trips can cost $300-$800 or more. Buying short sections may avoid a special delivery charge but can increase the per-foot price and the number of joints.
Excavated soil can add a meaningful expense when it cannot be spread on the property. Hauling and disposal may cost $100-$500 for a modest amount and more for large volumes, contaminated material, or distant disposal sites. Rocky soil, roots, buried concrete, and narrow side yards can slow excavation and increase equipment or labor charges.
Before work starts, confirm the route, identify underground utilities, and ask what happens if the crew encounters an obstruction. Utility locating is often available without charge through the applicable state system, but private lines such as irrigation, lighting, or propane piping may require separate locating. A contractor may charge a change order if an unexpected obstruction requires rerouting or additional digging.
Delivery, hauling, and difficult access can add several hundred dollars even when the pipe price is unchanged. A written quote should state delivery, disposal, equipment, and restoration charges rather than leaving them as open-ended extras.
