French Drains vs Surface Drains: What Collin County Homeowners Should Know
Both systems move water, but they solve different problems. Here's how to tell which one your yard actually needs.
When homeowners in McKinney, Plano, or Frisco call about a wet yard, one of the first questions is: do I need a French drain or a surface drain? They're not the same thing.
Surface drains
A surface drain is a catch basin — a grate at ground level connected to a pipe that carries water out to the street, alley, or a lower area of the yard. It's designed for water that's already puddling on top of the ground.
French drains
A French drain is a perforated pipe buried in a gravel-filled trench, wrapped in landscape fabric. It collects water from the soil itself — the wet, spongy area under the grass — and carries it out. It's designed for saturated soil, not just puddles on the surface.
When to use each
- Puddles that form quickly during a storm and drain in a day → surface drain
- Areas that stay soggy or squishy for days after rain → French drain
- Roof runoff pouring off a downspout → buried downspout extension into a pop-up
- Water flowing across the yard from a neighbor's slope → swale plus French drain
A lot of Collin County yards actually need both — a surface drain to grab the puddle and a French drain to pull the saturation out of the surrounding soil.
