A 24-inch reinforced concrete pipe (RCP) typically costs $45-$115 per linear foot for the pipe alone and about $150-$400 per installed foot for a standard drainage run. Pipe class, trench depth, soil, freight distance, and whether the quote includes excavation and backfill drive the final price.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 24-inch RCP pipe | $45/ft | $75/ft | $115/ft | Pipe supply only; class and joint affect price |
| Installed drainage run | $150/ft | $250/ft | $400/ft | Typical excavation, bedding, placement, and backfill |
| 100-foot installed run | $15,000 | $25,000 | $40,000 | Excludes major structures and unusual site work |
| Delivery | $500 | $1,500 | $4,000+ | Truck access and hauling distance matter |
What a 24-inch RCP drainage run usually costs
For a straightforward 100-foot run with ordinary access, a planning budget of $15,000-$40,000 is reasonable, with many projects landing near $25,000. That installed range assumes standard 24-inch pipe, routine bedding, a moderate trench, and no major utility conflicts or complex structures. Larger projects may receive lower pipe pricing per foot, while short runs can cost more per foot because mobilization and delivery are spread over fewer feet.
Pipe-only pricing is not the same as installed pricing. A 24-inch pipe is commonly supplied in sections around 8 feet long, so each piece is heavy and requires suitable lifting equipment. Assumptions: U.S. contractor pricing, ordinary site access, standard joints, and no major dewatering or rock excavation.
How pipe, trenching, and bedding shape the quote
Contractors may price pipe by the foot but quote installation as a complete excavation and placement package. The table separates common costs; overlapping line items can appear when a contractor bundles labor and equipment.
| Cost component | Typical range | Pricing basis | What changes it |
|---|---|---|---|
| RCP pipe | $45-$115 | Per linear ft | Class, joint, manufacturer, order size |
| Labor and placement | $25-$70 | Per linear ft | Crew size, access, alignment |
| Excavation and backfill | $40-$140 | Per linear ft | Depth, soil, trench width, compaction |
| Bedding and aggregate | $10-$35 | Per linear ft | Specified thickness and local material rate |
| Equipment and mobilization | $1,000-$6,000 | Per project | Crane or excavator needs, haul distance |
| Structures and connections | $800-$5,000+ | Each | Headwall, catch basin, manhole, tie-in |
Labor commonly runs about $75-$150 per crew hour when equipment and crew costs are included; the contractor’s estimate should clarify whether those expenses are already built into per-foot rates.
Class, trench depth, and soil can shift the price
Pipe strength class is a major specification. Class III is often a baseline for routine drainage, while Class IV or V can be required for greater loads, cover, or project specifications; stronger or specially specified pipe can add roughly 10%-35% to the pipe portion. The engineer’s plans and local requirements determine the correct class, not a cost-only substitution.
Depth changes excavation, shoring, and placement requirements. A trench under about 4 feet may be relatively straightforward, while depths above 5-6 feet can trigger protective systems and slower handling. Rock, groundwater, unstable soil, or nearby utilities can add $25-$150 or more per linear foot. Confirm the specified class, cover depth, and soil assumptions before comparing bids.
Regional freight and urban access change delivered rates
RCP is heavy and costly to transport, making the distance from a concrete pipe plant especially important. Projects within a practical delivery radius may see freight around $500-$1,500, while remote sites, restricted delivery windows, or multiple partial loads can push charges above $4,000. Rural projects may have lower labor rates but higher hauling costs.
Compared with a typical Midwest or South estimate, large coastal metro projects can run about 10%-25% higher because of labor, traffic control, and limited work access. Rural or small-market totals can be 5%-15% lower when pipe is nearby and equipment access is easy, but those savings can disappear with long-distance freight or low-volume orders.
Delivery, lifting, and disposal charges to check
Ask whether the bid includes unloading, pipe placement, and moving sections from the truck to the trench. A crane or larger excavator may add $500-$2,500 per day, and difficult access can require additional mobilization. Disposal of excavated soil may add $10-$40 per cubic yard, with higher rates for contaminated material or long haul distances.
Permits, traffic control, and utility locating are sometimes separate. Allow roughly $200-$2,000 for routine local approvals and marking, but road closures, inspections, or public right-of-way work can cost substantially more. Get exclusions in writing so a low per-foot figure does not conceal major site charges.
How many crew hours does a 100-foot installation take?
A clear, accessible 100-foot run may take a small crew about 2-4 working days, including trench preparation, setting pipe, and backfill. A crew of three or four with an excavator and lifting equipment could represent approximately 48-128 crew hours. Rock, water, shoring, or frequent utility crossings can extend the schedule and raise labor costs.
Weather and delivery coordination also matter: a truck delay can leave equipment and workers idle, while wet conditions may require pumping or additional stabilization. Request separate estimates for pipe, excavation, placement, and restoration when the schedule or site conditions are uncertain.
Three 24-inch RCP quotes for different job conditions
A simple 100-foot run with 4-foot cover, nearby pipe supply, and ordinary soil might total $18,000-$24,000, or $180-$240 per foot. This assumes standard pipe, limited structures, and around 2-3 days of work.
A 100-foot suburban project with 6-foot cover, one catch basin, and moderate haul distance could reach $27,000-$36,000, or $270-$360 per foot. The added depth, structure, freight, and protective measures account for the increase.
A 60-foot urban replacement with pavement removal, utility conflicts, and restricted truck access could cost $24,000-$40,000, equivalent to $400-$667 per foot. The short length spreads traffic control and mobilization across fewer feet. Examples are budget scenarios, not contractor bids; local plans and site review determine actual pricing.
Where to reduce the 24-inch pipe installation bill
Compare at least three itemized bids using the same pipe class, joint type, trench depth, bedding specification, and restoration scope. Confirm whether each price includes freight, disposal, structures, compaction testing, and permits. A lower quote that omits one of these items may not be less expensive after change orders.
Where engineering allows, coordinate delivery with the excavation schedule, avoid unnecessary extra trench width, and reuse suitable excavated soil for backfill. Combining this work with nearby drainage or utility work may reduce mobilization charges. Do not downgrade pipe class or skip specified bedding to save money; those changes can risk failure and costly rework.
The most reliable savings come from controlling access, haul distance, and scope—not from changing structural specifications without approval.
