A concrete catch basin collects surface runoff, traps sediment below its outlet, and routes water into a storm pipe. Installed totals range from small residential drainage jobs near $600 to public-road structures above $15,000, with excavation depth, pipe work, access, pavement repair, and traffic controls driving the spread.

Homeowner quotes may combine the basin, grate, trenching, outlet pipe, aggregate, hauling, and ground repair into one project price. Public bid schedules separate some of those items, which makes direct comparisons difficult. As of June 2026, HomeAdvisor placed professional yard-drainage projects at $2,147 to $7,170, with excavation and grading alone listed at $1,025 to $6,050 on its yard drainage cost page.

A concrete catch basin is priced per installed structure or per drainage project. Basin size, labor versus materials, outlet depth, surface type, and equipment access decide whether the job lands near residential drainage rates or municipal construction bids.

TL;DR: A residential catch basin installation can land near $600 to $2,100, but large concrete structures with deep excavation, road restoration, or storm-sewer connections can reach $3,000 to $15,000 or more.

What you’re actually buying

A concrete catch basin is a buried drainage chamber with an open grate or curb inlet at the surface. Water enters the chamber, heavier debris settles into the sump, and the remaining flow exits through a connected storm pipe. The assembly may include a precast base, riser sections, a frame, grate, pipe penetrations, seals, bedding stone, and compacted backfill.

The structure serves a different purpose from a French drain, which gathers water through perforated pipe and stone, or a dry well, which holds runoff for infiltration into soil. A light plastic inlet may work in a lawn receiving modest flow. Concrete is suited to deeper pipe elevations, large openings, vehicle loads, parking lots, street edges, and sites where a rigid chamber is specified. The National Precast technical brief describes steel reinforcement, wheel loads, soil bearing capacity, buoyancy, pipe openings, and site-specific sizing as design inputs.

A worked total

A public bid schedule can show how the basin and pipe connection form separate charges. In De Pere’s March 2025 tabulation, one bidder listed a Type B catch basin at $3,115 (about 2.6 full-time workweeks at $30 per hour) each and a connection to an existing storm-sewer pipe at $1,000 each. The same schedule placed a concrete collar at $450. These figures appear in the city’s Project 25-02 bid tab.

• Type B concrete catch basin: $3,115
• Existing storm-pipe connection: $1,000
• Concrete collar where required: $450
• Illustrated itemized total: $4,565

The arithmetic is $3,115 + $1,000 + $450 = $4,565. That is a planning example built from one bidder’s unit prices, not a promised homeowner quote. Excavation, restoration, traffic control, testing, and mobilization may sit inside other contract items or project overhead. The same bid tab shows four Type B basin bids from $3,115 to $4,062. The $947 difference equals about 30% of the low bid, showing how contractor pricing can shift before pipe or restoration charges are added.

Labor, concrete, and equipment

The precast chamber is only one part of the invoice. The crew must lay out the inlet elevation, locate utilities, excavate below the outlet pipe, prepare a stable base, lift the chamber into place, connect pipe, seal openings, place backfill in lifts, compact the excavation, and rebuild the surface. A large unit may call for an excavator or backhoe with enough lifting capacity, plus a skid steer, compactor, dump truck, and trench-safety equipment.

Material charges can include the basin base, risers, top slab, frame, grate, adjustment rings, pipe, fittings, stone, concrete, and pavement products. Oldcastle lists base sections, risers, knockouts, frames, and grates among the parts used in its precast basin assemblies. A quote that says “catch basin” without naming these parts leaves room for later additions.

Residential drainage references show the gap between component and project pricing. Angi’s May 2026 data lists catch basin materials at $50 to $500 (about 0.2 to 2.1 full-time workdays at $30 per hour) each, perforated pipe at $1 to $5 per foot, gravel at $30 to $60 per ton, and fittings at $2 to $10 each in its yard drainage material table. Those figures cover light residential components, not traffic-rated precast structures.

Installed price bands

Small lawn projects sit at the low end when excavation is shallow, machinery can cross the yard, and the discharge pipe is close. Driveway and parking-area work moves higher because the grate and structure must suit vehicle loading, and the contractor must cut and rebuild the hard surface. Public-road work adds inspection, traffic control, deeper utilities, larger structures, and stricter compaction requirements.

Project type	Cited price band	Main scope signal
Residential catch basin installation	$590 to $2,100	Shallow yard work with residential pipe
Type B municipal basin	$3,115 to $4,062	Specified precast structure priced per unit
Anchorage constructed catch basin	$3,000 to $15,160.18	Public construction with broad site variation
Type I catch basin or manhole	$6,500 to $15,850	Larger combined storm structure

The 2024 Anchorage records report an average Type I catch basin or manhole bid of $10,945.06, compared with a low of $6,500 and a high of $15,850, in the city’s storm-drain bid tables. Dividing $10,945.06 by De Pere’s $3,115 low Type B bid gives about 3.5. The structures and contract conditions differ, so that ratio measures scope separation rather than regional inflation.

Line items

Buried conditions create the largest change-order risk. Soft soil may need removal and imported aggregate. Groundwater may require pumping. An outlet pipe can appear sound at the surface but prove crushed, offset, or set at the wrong elevation once exposed. Utility congestion may force hand digging or a different basin location. Deep excavations can require shoring, a wider work area, or added hauling.

Surface repair also changes the bill. Lawn restoration may involve topsoil, seed, and erosion control. Gravel needs replacement and compaction. Asphalt work requires saw cutting, base repair, paving, and joint sealing. Concrete driveways or sidewalks add demolition, forming, reinforcement, placement, curing time, and disposal. Related budgets may need separate allowances for yard grading work when the inlet elevation alone cannot direct runoff.

Hidden-cost allowance: keep room for pipe repair, unsuitable soil, dewatering, disposal, and pavement restoration. On residential drainage projects, those additions can move a small basin job toward the cited $2,147 to $7,170 full-system band.

Contract language matters. Anchorage specifications treat removal, relocation, abandonment, and grade adjustment as separate storm-drain operations in the city’s Division 55 requirements. A homeowner quote should make the same distinctions in plain language.

Regional pricing and access

Access can matter as much as basin size. An open front yard may admit a backhoe and dump truck. A fenced rear yard may limit the contractor to a compact excavator, smaller loads, and repeated trips. Narrow gates, overhead wires, mature trees, retaining walls, and septic components can slow production. Hauling also rises when disposal sites or aggregate yards are far from the property.

Climate and local construction rules shape the excavation. Cold regions may use deeper storm piping and stronger frost-resistant details. Dense cities may require street-opening permits, lane controls, inspections, or restricted working hours. Areas with poor soil may call for thicker bedding and a wider excavation. These items explain why a quote from another state may offer weak guidance even when the basin dimensions match.

HomeGuide’s February 2026 pricing places subsurface yard drainage at $8 to $15 per linear foot or $1,200 to $8,000 per project, and catch-basin storm systems at $8 to $15 per square foot, on its drainage installation report. Pipe length and treated area can overtake the basin itself. A project that also needs aggregate can use current local delivery quotes rather than relying on older Class 5 gravel figures.

Three catch basin jobs

Budget yard case. A shallow basin at a lawn low point has machine access and a nearby discharge line. Angi’s June 2026 Raleigh data places installed catch basins at $590 to $1,970 in its Raleigh drainage pricing. Pipe length is the main driver in this case. A longer trench can raise labor and materials even when the inlet stays small.

Cold-climate residential case. The basin serves snowmelt and rainfall, with deeper excavation and a longer run across the property. Angi’s June 2026 Minneapolis report lists catch basin installation at $630 to $2,100 in its Minneapolis drainage data. Depth and seasonal ground conditions carry more weight than the grate.

Roadside public case. The inlet sits beside active traffic and connects to a municipal storm sewer. The primary drivers are structure specifications, traffic control, inspection, pipe connection, and pavement restoration. Anchorage recorded constructed catch basin bids from $3,000 to $15,160.18. This case should not be used as a direct residential allowance because public contracts carry work rules and risk that do not appear in a backyard installation.

Who this drainage expense fits

A concrete basin earns its place where surface water needs a defined inlet, sediment storage, a durable chamber, and a pipe outlet. It can also make sense where a plastic box would sit under vehicle loads or where the outlet depth exceeds the geometry of a small retail inlet. The drainage path must have an approved destination. A basin cannot solve ponding when the connected pipe has nowhere to discharge.

Makes sense if

• Runoff collects at a low point beside a driveway, parking area, curb, or paved walk.
• The grate and chamber must withstand wheel loading.
• Sediment needs space to settle below the outlet.
• A deep storm pipe requires a rigid structure with sealed penetrations.

Doesn’t make sense if

• The problem is groundwater better handled by a French drain system.
• Regrading can move runoff without a buried inlet.
• The site has no lawful outlet or suitable infiltration area.
• The existing basin only needs cleaning, grate replacement, or grade adjustment.

Ask bidders to identify basin dimensions, load rating, grate type, pipe size, excavation depth, spoil removal, aggregate, compaction, surface repair, permits, and cleanup. A low number that omits pavement or outlet work may finish above a higher fixed-scope quote.

Answers to Common Questions

How much does a residential concrete catch basin cost to install?

Current residential city reports place catch basin installation near $590 to $2,100. Deep outlets, long pipe runs, poor access, or driveway repair can move the total into a broader drainage-project band.

Why does a concrete basin cost more than a plastic inlet?

Concrete units are heavier and may need machinery for excavation and placement. They can also include traffic-rated frames, grates, risers, reinforced walls, and larger pipe openings.

Can a catch basin fix every wet-yard problem?

No. It handles surface runoff when water can enter the grate and leave through an outlet. Saturated soil, hillside seepage, and foundation water may call for grading, a French drain, or another drainage design.

Should the quote include pavement repair?

Only when the scope states it. The contract should identify demolition, hauling, aggregate base, asphalt or concrete replacement, joint work, and final cleanup.
