For a typical 50-100 linear foot French drain system. Includes pipe, gravel, filter fabric, and installation. Caliche removal adds significantly.
Drainage costs vary widely depending on the system type your property needs. Here is how the four main options compare in the High Desert.
| System Type | Cost per Linear Ft | Typical Project | Best For |
|---|---|---|---|
| French drain | $15-$25 | $1,500-$2,500 (50 ft) | Yard flooding, soggy areas |
| Channel drain (trench) | $25-$50 | $900-$1,900 (20 ft) | Driveways, patios, pool decks |
| Dry well | $500-$1,500 each | N/A | No surface discharge available |
| Full system (French + channel + dry well) | Varies | $3,000-$8,000+ | Major drainage problems |
A $5,000 drainage system = ~$75/mo with approved financing through Lyon Financial. Up to $200K, terms to 20 years, no equity required.
Here is where the money goes on a typical 50 linear foot French drain installation in the High Desert. This is the most common residential drainage solution we install.
| Component | Cost |
|---|---|
| Excavation (trench 12-18″ wide, 18-24″ deep) | $200-$300 |
| Perforated pipe (4″ PVC SDR 35) | $75-$100 |
| 3/4″ clean crushed stone + filter fabric | $150-$250 |
| Labor | $500-$750 |
| Outlet construction (pop-up emitter or daylight) | $100-$200 |
| Total | $1,025-$1,600 |
Note: These numbers assume sandy or loamy soil. If you hit caliche during excavation, add $75-$100/day for jackhammer rental or $250-$350/day for a mini excavator. In Adelanto, caliche removal can double the excavation line item.
Channel drains (also called trench drains) collect surface water from hard surfaces like driveways, patios, and pool decks. Here is the breakdown for a typical 20 linear foot installation.
| Component | Cost |
|---|---|
| Channel + grate | $400-$1,000 |
| Concrete bed | $100-$200 |
| Outlet pipe (4″ solid PVC) | $100-$200 |
| Labor | $300-$500 |
| Total | $900-$1,900 |
Polymer concrete channels with stainless steel grates run higher than plastic channels with galvanized grates, but they handle desert UV and heat cycling without warping or cracking. For driveways, we recommend polymer concrete rated for vehicle loads.
Drainage pricing in the High Desert has variables that do not exist in coastal or valley estimates. Desert soil conditions and storm patterns drive most of the cost variation.
People assume the desert does not have water problems. The opposite is true, the High Desert has some of the worst drainage conditions in Southern California because of three factors working together.
A properly installed drainage system is low maintenance, but it is not zero maintenance. Here is what to expect over the life of the system.
| Frequency | Task | Cost |
|---|---|---|
| Annual | Inspect outlets, clear debris, verify slope and flow | $50-$150/year |
| Every 3-5 years | Clear sediment from drain rock, check filter fabric integrity | $200-$500 |
| As needed | Flush pipes with garden hose to clear sediment buildup | Free (DIY) |

$15-$25 per linear foot installed, or $1,500-$2,500 for a typical 50 ft residential system. That includes excavation, perforated pipe, drain rock, filter fabric, and outlet construction. Caliche removal can add 30-100% to excavation costs in the High Desert, Adelanto properties are hit hardest, while Victorville near the Mojave River often has clean sandy soil.

Yes. The High Desert gets only 5-6 inches of rain per year, but it comes in sudden monsoon bursts that overwhelm hard-baked soil. Add caliche (impermeable hardpan 6-40 inches below the surface) and you get standing water, foundation damage, and Gravity walls, geogrid-reinforced walls, and engineered walls failure. Every hardscape project we build includes drainage planning because the consequences of skipping it are expensive.
Usually caliche. This cement-like calcium carbonate layer sits 6-40 inches below the surface across most of the High Desert and blocks water from draining deeper into the ground. Water pools on top of the caliche, creating a “perched water table.” The solution is intercepting water with French drains before it saturates the soil and directing it to a proper outlet, either daylight discharge on a slope, a pop-up emitter, or a dry well.
18-24 inches minimum. The trench should extend below the water-saturated zone so the perforated pipe can intercept groundwater before it reaches your foundation or hardscape. In the High Desert, you may need to go deeper if caliche is present at shallow depth, the drain needs to sit above the caliche layer to catch water pooling on top of it, then route it laterally to a discharge point.
No. California law requires you to discharge to your own property, a public swale, or a storm drain connection (which requires municipal approval from your city). Pop-up emitters and dry wells are the most common solutions for keeping water on your property. We design every drainage system with a legal outlet and can coordinate with San Bernardino County when storm drain connections are needed.
PVC drain pipe lasts 50+ years. HDPE pipe also 50+ years. Filter fabric holds up for 20-30 years when buried and protected from UV. Gravel is indefinite but may need topping if eroded near outlets. Metal grates on channel drains last 15-25 years depending on material, stainless steel outlasts galvanized in desert conditions. Annual inspection ($50-$150) and occasional flushing keeps everything functioning at peak capacity.
Every property drains differently. Soil type, caliche depth, grade, and hardscape all affect the solution. Get a free on-site assessment with a custom drainage plan.
