Typical price ranges around Waxahachie
Most residential french drain projects in Ellis County land in a broad range depending on length, depth, and whether the crew is fighting standing water and heavy clay. Use these numbers as a planning reference, not a quote.
- Short french drain, 20 to 40 linear feet: roughly $1,500 to $2,500 for one problem area with a nearby outlet.
- Standard residential run, 40 to 80 linear feet: roughly $2,500 to $4,000, often the sweet spot for a soggy back yard or a side yard between houses.
- Longer or deeper drain, 80 to 150 linear feet: roughly $4,000 to $6,500 when the trench needs to cross a full lot or run deep to daylight.
- Full yard drainage system: roughly $5,000 to $12,000 when the plan pairs french drains with multiple catch basins, downspout tie-ins, and regrading.
- Per linear foot ballpark: most Waxahachie installs price out somewhere between $40 and $80 per linear foot installed, more when the trench has to go deep through solid clay.
French drain vs a full drainage system
A french drain by itself is a single subsurface trench with perforated pipe wrapped in gravel and fabric. It solves one problem, usually a wet low spot or a soggy area near a fence line. A full drainage system connects french drains to catch basins that grab surface water, downspout extensions that move roof water away from the slab, and one or more outlets where everything daylights. Many Waxahachie yards need the full system because Blackland clay does not let water percolate on its own, and solving one wet spot often just moves the water to the next low point.
What actually drives the price on your lot
- Linear feet. Longer trenches use more pipe, more gravel, and more labor. Length is the biggest single line item.
- Trench depth. A shallow lawn drain is faster than a deep drain along a foundation. Depth also drives how much spoil the crew has to haul off.
- Clay soil difficulty. Waxahachie Blackland clay is heavy, sticky when wet, and rock-hard when dry. Both extremes slow trenching and wear equipment.
- Outlet distance and elevation. A drain is only as good as its outlet. A yard that slopes to daylight is cheap. A flat lot that needs a pop-up emitter or a pump adds real cost.
- Catch basins and downspout tie-ins. Each basin and each downspout connection adds fittings, fabric, and time.
- Site access. Narrow gates, mature trees, fences, and hardscape that has to be protected all add labor hours.
- Restoration. Fresh sod, mulch, and hardscape put-back are separate line items on many quotes.
Why Blackland clay raises the price
Ellis County sits on Blackland Prairie clay that swells shut when wet and shrinks and cracks when dry. That matters for drainage cost in three ways. First, the clay does not percolate, so french drains cannot simply soak into the ground. Every trench needs a real outlet, which usually means a longer run and more pipe. Second, wet clay is heavy and sticky, and trenchers and mini excavators cut slowly through it. Crews sometimes have to wait a day or two for a soaked lot to dry before digging. Third, deeper drains along foundations need to be dug carefully so trench walls do not collapse, which adds time and sometimes shoring.
Ongoing costs after install
- Annual catch basin cleanout, especially in fall when leaves clog grates.
- Occasional camera inspection of long runs if flow drops.
- Sod and mulch touch-up over the trench line for the first season.
