What is a French Drain?
Drainage Trench
A Drainage Trench is where a French Drainpipe is located. The Perforated Drainpipe is placed in the bottom of the Drainage Trench On top of the Trench Liner. It needs to be in a low area where the water is standing or flowing toward. This is called the “Intake,” Part of a Drainage System. A French Drain takes in water.
Transition Trench
A Transition Trench is the location of the Transition Pipe. It is connected to the French Drainpipe. It takes the drain water to the dedicated exit.
Trench Liner
The White Material is the Trench Liner. The black material is the Pipe Filter.
A liner is placed in the bottom of the Drainage Trench. This liner allows water to enter the French Drain from the dirt surrounding the French Drain. Underground water, AKA “Sub-Surface Water, “can be drained away.

A little bit North of Downtown Oklahoma City, Oklahoma Drainage installed a 6-inch French Drain between two businesses which were less than three feet apart. The French Drain went between a Law Firm and a Tire shop. Water was leaking through the walls of both businesses. Gutters between the two establishments were dumping a huge amount of water. We installed a 6-inch French Drain between the gutters.
It took a long time to get the dirt out of the trench for the French Drain. It was a very tight fit. We had to use a little red wagon to haul out the dirt for the French Drain and haul back in the crushed limestone for the French Drain. It looked a little silly, but it was the only thing we could find that was narrow enough to fit between the buildings. A French Drain that normally would take 1 day to install took three.

French Drains can utilize several types and sizes of French Drainpipe. An older type that is not commonly used any more is 4-inch PVC Pipe with large half inch holes drilled in the Pipe. This doesn’t work very well, Because the holes are too large and the number of holes in the French Drainpipe are too few. Also, there is no filter or “Soc” around this particular French Drainpipe. If it is used in sandy or loose soil the holes will clog and the pipe will fill up with sand. PVC French Drainpipe should be avoided.
ADS French Drainpipe is much better, the holes are smaller and much more numerous. It also comes inside a soc that acts as a filter and helps keep sand and debris out of the French Drainpipe. It works very well.
For Small business and Residential French Drains, four-inch ADS Perf/Soc French Drainpipe is adequate and the most common. It is used for the majority of all Drainage Systems.
French Drains can be installed using 3-inch ADS Perf/Soc but many times it is too small and can be overwhelmed by a heavy rain or from a bad design. (Too many gutters down spouts connected directly into the French Drain, For Example) Three Inch French Drainpipe should be avoided if possible.
6 Inch Pipe
Six-inch ADS Perf/Soc French Drainpipe is usually a good idea when possible. It carries a much larger volume of water. Six Inch pipes are rarely overwhelmed.
