Precision Drainage: Achieving the Perfect Ecosystem for Your Lawn

A French drain collects water in saturated soil. A catch basin collects water flowing across the surface. They solve different parts of a drainage problem, and putting the wrong one in the ground can leave you with the same wet yard.

Before choosing a drain, look at where the water comes from and where it can go.

When a French drain fits

If the ground stays wet after the surface puddles disappear, groundwater collection may be part of the answer. Our burrito-wrap French drains use perforated pipe surrounded by clean, washed angular stone and enclosed in non-woven drainage geotextile.

Water moves through the soil into the drainage assembly, enters the perforated pipe, and follows the route toward a suitable outlet. The fabric separates the surrounding soil from the stone. Keeping soil out of the stone matters because the spaces between the stones are part of the water's path.

That assembly needs to be placed where it can intercept the water. A neatly buried pipe at the wrong elevation doesn't solve the problem.

When a catch basin fits

Water running off a patio, driveway, or sloped yard needs a way into the system at the surface. A catch basin is an inlet with a grate. We place it at the collection point and shape the surrounding ground so water can reach it.

Solid pipe then carries the collected water toward the discharge. A basin sitting above the surrounding low spot can miss the runoff even when the pipe is clear.

Roof water needs its own explanation

A downspout concentrates water from the roof. We use solid conveyance pipe to move that water along the intended route. We don't treat a perforated groundwater drain as an interchangeable downspout extension.

Some properties need more than one collection method. The important distinction is what each component collects and how the combined system discharges.

Check the outlet before buying the drain

Neither a French drain nor a catch basin makes water disappear. The outlet elevation, route, receiving area, and capacity all matter. If gravity can't move water to a suitable discharge point, the plan may need to change or include pumping.

The right question isn't simply which drain is better. It's which water source you need to collect, and what path will actually get that water out of the problem area.
