French Drain Installation—   French Drains are designed to do a lot of things.  If you have an area that has unwanted water standing in it or running across it, a French Drain can be the answer.  A French Drain is a trench that runs across the Drainage Problem Area.  A French Drain Pipe is placed in the bottom of the trench.  The French Drain Pipe is perforated with thousands of small holes.  In most cases the Drain Pipe has a nylon soc around the pipe to act as a filter for the French Drain.  The French Drain trench is then filled with some type of small rock or stone.  We typically use crushed 1 inch Lime Stone to cover the French Drain Pipe.  The dirt that was dug out of the trench is taken away or spread out around the French Drain.  The Lime Stone replaces the dirt and fills the French Drain Trench all the way to the surface.

Covering a French Drain with dirt is a bad idea.  Water can’t get into the drain through the stones if it is clogged with dirt.  If you are more concerned about how it looks over what it does, then don’t install it in the first place.  French drains can move a lot of water and protect property such as foundations, sidewalks, plants, yards just to mention a few things.  If you don’t like how a French Drain looks then change it.  Put Stepping stones on top of it, use river rock to improve the look, You are limited only by your own creativity.

This week we installed a 6 Inch French Drain in Oklahoma City.  Water was running down the hill, under the back fence, into the back yard, across the sidewalk, and into the side door going into the garage.  After every heavy rain, water was getting into the garage.  We installed a 6 Inch French Drain across the back yard to divert the water.  We also connected the Gutter Down Spouts Directly into the French Drain.  Once the French Drain was down hill from the house, we changed from French Drain Pipe to solid 6 inch ADS Drain Pipe and continued across the front yard to the street.  Once at the curb, we cut the curb with a concrete saw and installed a Curb Outlet for the French Drain.  Problem solved!

Installing French Drain in standing water

Something to think about — Most people see and deal with what is obvious when it comes to Drainage Problems.  Surface Water is “Obvious”!  People see it washing over the surface into the area that collects the water.  Simple enough.

A good place for a French Drain

Water Standing in your yard can be tricky.

Designing a Drainage System to intercept the Surface Water is the first step, but many times is not the only step.  Often Sub-Surface Water( Water Running Under Ground ) is not accounted for by people with less experience in designing Drainage Systems.  They install A Drainage System that uses Surface Drains to Intercept the running surface water.  Sometimes that works if that is the only water source to the Problem Drainage Area.

Surface Drains drain surface water away only.  Sub Surface water runs right around them and into the same Problem Drainage Area.  There may be less water there than there was before but the problem still remains.

A French Drain is the solution when water is running into a problem area over the surface and under ground.  A French Drain solves both problems and the area will be dry.

WHAT SIZE DRAIN PIPE FOR FRENCH DRAINS?

French Drains can be decorated with many types of stone

French Drains can be decorated with many types of stone

French Drains can utilize  several types and sizes of French Drain Pipe.  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 Drain Pipe are too few.  Also there is no filter or “Soc” around this particular French Drain Pipe.  If it is used in sandy or loose soil the holes will clog and the pipe will fill up with sand.  PVC French Drain Pipe should be avoided.

ADS French Drain Pipe 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 Drain Pipe.  It works very well.

For Small business and Residential French Drains, Four inch ADS Perf/Soc French Drain pipe is adequate and the most common.  It is used for the majority of all French Drains installed.  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 gutter down spouts connected directly into the French Drain, For Example)  Three Inch French Drain Pipe should be avoided if possible.

Six inch  ADS Perf/Soc French Drain Pipe is usually a good idea when possible.  It carries a much larger volume of water.  Six Inch French Drains are rarely overwhelmed.

Installing Gravel on top of a 6 inch French Drain

The Drawbacks to 6 inch French Drain installation are:  1.  The Materials Cost is higher for six-inch French Drain Compared to Four Inch Pipe.
                                                                                                                    2.  Many times 6 Inch French Drain Pipe is too large for many applications, Such as going under a fence or sidewalk.  
                                                                                                                   3.  The trench for a 6 inch French Drain must be much larger than a 4 Inch
                                                                                                                   4.  The amount of gravel or limestone or River Rock used to Cover the 6 inch French Drain is Much larger
 
All things being considered, the performance and longevity of a 6 inch French Drain is well worth it if you are trying to protect something of value to you!  If the higher cost and the additional labor and materials are not a problem and 6 inch French Drain pipe is not too big for what you want to do then a 6 inch French Drain would be the best.

A good place for a French Drain

We just finished a 4 inch Drainage System in Yukon.  It was a complicated system to install.  It utilized 4 inch French Drain in the flower beds,  12 inch Surface Drains on the side of the house,  6 inch French Drain along the garage foundation with 2 Pop – Up Emitters in the back yard and 3 Curb Fittings in the front.    First we installed 4 inch French Drain in the flowerbeds on both sides of the front door.  We connected 4 inch solid Drain Pipe into the French Drain and ran them underside walk to the curb.  Next we cut the curb with a concrete saw and installed 3 curb outlets for 3 separate French Drains.

Next we installed 4 12 Inch Drain Basins with grates along both sides of the house continuing with Solid Drain Pipe to the Pop-Up Emitters on the back fence. Finally we completed the Drainage System by installing a long run of 6 inch French Drain down the side of the garage foundation.   Installing the French Drains in the flower beds was the most difficult and took the most time.  Each French Drain took over a ton of crushed limestone to fill the French Drain trench.  The Six inch French Drain took even more limestone.

French Drains as part of a Drainage System – 

Many times people use the term ” French Drain” as general name for a Drain used in or around your home.  French Drains are designed to move a lot of water over a large flooded area.  They are also designed to take water in on the surface of the ground or below the surface of the ground.  This is very important if the water coming into the flooded area is moving through the ground or coming up from underneath.  ” Sub Surface Water Movement.”  The picture below is not a French Drain!

A French Drain looks like this

river rock french drain

A French Drain Can Handle Standing Water

A French Drain can take in water in a broad area.  It can move a much larger volume of water compared to a Surface Drain.  Also, it can move sub surface water moving into the area where a Surface Drain won’t move any water at all.

Surface Drains are designed to move surface water only on a smaller scale in confined areas.

Each solves specific drainage problems.  A Drainage System may use one or both together or even several using many types of drains.

Do you have standing water in a large area in your yard?  Typically this calls for a French Drain.  A French Drain is a great way to control standing water in a large grassy area.  It can also protect areas from flooding to a certain degree.  As long as the French Drains capacity to move water is not exceeded.  If the French Drains capacity is exceeded then water will stand in the drainage area until the rain stops and the drain has time to catch up.  A good way to prevent this is to install a bigger French Drain with a larger pipe.  The difference between a 3 inch French Drain and a 6 inch French Drain is huge.

Another way to beef up a French Drain is to connect gutter down spouts in front of the French Drain.  The water coming off the roof causes suction in the French Drain Behind it.  This greatly increases the French Drains ability to move water without increasing the size of the French Drain Pipe.

Recently we installed a French Drain inside the court yard of a rest home in Norman.  We had several interesting challenges to overcome that were not typical for a French Drain Installation.  The court yard was in the center of the home and was a secure area for the patrons.  We had to put down painters tarps to run our wheel barrows over.  We took out 44 loads of dirt and brought in 52 loads of Crushed one inch lime stone for the French Drain.  Each trip was over a hundred yards from the trailer in the parking lot, in the front door, down the hall, making two turns along the way.  Each time we had to be escorted by security.  Needless to say, the installation of this particular drainage system took a while.In the above picture, the French Drain runs along the low area crossing all the areas where water would stand each time it rained.

When a French Drain is installed, a big mistake that is made by many people is to cover up the gravel with dirt.  This is a big mistake.  Basically it is ” Putting the cork back in the bottle.”  If the French Drain is in full sun and has a type of grass surrounding it that spreads on its own such a ” Tift” or “Bermuda” , Grass will grow over it and the French Drain will eventually disappear.  Grass covering a French Drain is a good thing if it grows across the drain without adding dirt.  The Grass thatch acts a water filter preventing clogging and extending the life of the Drainage System.

When a French Drain is in Full Shade, or the surrounding grass will not spread on its own, such as with Fescue,  other steps must be taken.  One option is to just leave it alone.  If you don’t mind how it looks, it will drain a large amount of water for many years.  Many times a French Drain can be a landscaping focal point.  They can be dressed up with all kinds of Rocks and Stones and Plants.

 

Just what is a “French Drain?”  Many times people incorrectly

French drain installed
A French Drain can protect your foundation!

use the phrase, “French Drain,”  to apply to many different types of Drains that could be used in a Drainage System.  The term is widely used and many times incorrectly connected to “Surface Drains,” or “Channel Drains.”

A Surface Drain has a grate that sits on top of a basin.  The basin is underground.  A Drain Pipe is connected underground to an outlet on the Drain Basin Storm-Water Drains through the grate into the Drain Basin.  Once in the Drain Basin, water travels out of the basin through a Drain Pipe.  The Storm-Water continues downhill in an underground Drain Pipe to an exit point.

THIS IS NOT A FRENCH DRAIN!

A Surface Drain may come in many different shapes or sizes.  The Drain Grate may be round or square.  Here is a picture of a common Surface Drain.

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.

A French Drain is completely different from a Surface Drain.  A basic French Drain consists of a Perforated Drain Pipe in the bottom of a trench.  The Drain Pipe should have a neoprene sock around the Perforated Drain Pipe.   This is to ensure that the Drain Pipe does not become clogged.

The dirt that was taken out to make the trench is hauled away.  It is replaced by some type of small stone or gravel depending on what is desired or available.  I prefer crushed 1 inch lime stone.  It is the most economical option in my area.  Pea Gravel or some other type of small stone can work just as well.    The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level).   In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed.  This helps maintain the integrity of the trench over time.  It also increases the cost of the French Drain and the amount of time to install it.  I install a trench liner in a French Drain about 20% of the time.  Most of the time a liner in not needed.

A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations.  It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.
The main downfall of a French Drain is that they, for the most part aren’t very pretty.  They don’t look very nice in a yard once they are completed.
Depending on the area the French Drain is installed and the type of grass around the French Drain, will dictate whether grass grows over the lime stone.  Grass can grow up and through the gravel in the French Drain over time eventually covering the gravel.  This is Ok.  It won’t have a measurable effect on the performance of the drain.
DONT COVER THE GRAVEL IN THE FRENCH DRAIN WITH DIRT.  THE FRENCH DRAIN WON’T WORK IF THE TRENCH IS CLOGGED WITH DIRT.  DON’T EVEN INSTALL IT IF YOU ARE GOING TO COVER IT UP WITH DIRT.

A French Drain will move large amounts of water from the Drainage Problem Area to the Exit point.

A French Drain will Drain away water that gets to the Drainage Problem Area in 3 ways.

1.  Water gets to the problem area by falling from the sky.

2.  Water gets to the problem area by flowing down hill over the ground.

3.  Water gets to the problem area by flowing underground. (Sub-Surface water flow)

Number 3, Sub-Surface water flow is the big consideration.  When doing a Drainage Diagnostic, this is the area that is many times missed or not considered by less experienced companies.  Oklahoma  Drainage and Sprinkler Repair  relies on 26 years of experience.  Many Times it is cheaper and more effective to install a French Drain over a Surface Drain.  A Surface Drain can’t move as much water as a French Drain, and a Surface Drain can’t Drain away Sub-Surface waterSurface Drains should be installed in areas where the Drainage Problem area is smaller and is not affected by sub-surface water.

The draw back to a French Drain, is that it is not a pretty as a Surface Drain.

French Drains do a great job running along foundations and driveways.  A French Drain will keep water away from cement and prevent damage to concrete if water should freeze up against it.  A French Drain can keep your foundation Dry.

The Drainage part of our company name means that we solve water problems for people in Oklahoma.  Heavy rain is becoming more common.  Back in 1993 when I first started, a hard rain was considered to be about an Inch per/hour.  It was fairly rare but not too uncommon.  Today things are different.  A weather report of rain fall at or above 4 inches per/hour was not uncommon in 2019.  Excess water causes all types of damage to property both residential and commercial.

Our Drainage Systems drain water away from places you don’t want it to be.  You might have water standing along the foundation of your house, or inside your basement.  You might have water on your driveway or flowerbed too.

Designing a French Drain or a Drainage System

When I talk to a potential customer while doing a Drainage System estimate, I take a lot of things into consideration.  First I have the Customer show me where water is standing or where it is going that it shouldn’t.  This is part of defining the specific problem area.  Sometimes the Water Problem Area is larger and more involved than the customer realizes.  Once the Water Problem Area is clearly defined,  the next step is to determine how the water is getting to the problem area.  Many times there is more than one Water Source to the Water Problem area.  A big mistake in Drainage System Design is to stop once the most obvious  Water Source is found.  A Drainage System Designer must be a detective to some degree.  For Example:  Water running down the hill and onto the back patio might be the most obvious water source.  Sub-surface water or a neighbor’s new gutter downspout could also be contributing.  Most of the time water gets into the problem area from more than one source.

Next you must decide where to take the water.  This is determining an Exit Point for the Drainage System.  If possible you want your exit point to be down hill from the problem area.  If it is up hill in all directions from the problem area, then the only solution is a Sump Pump.

Once an exit Point is determined, you must ask yourself if there is any way to install two exit points.  Usually this can only work when an exit point can work on both ends of a Drainage System.  The benefit of two Exit Points in a Drainage System is it greatly increases the water capacity for the Drainage System.  It can move much more water faster during a heavy rain than a system with just one Exit Point.  Most Drainage Systems can only utilize one Exit Point.  In 21 years of Drainage System Installation,  I would say 10% of our Drainage Systems have two Exit Points.

Next we have to decide what type of drain to install in the problem area.  If it is a small area with one water source, Usually a Surface Drain is best.  If the water problem area is large with one or several water sources, a French Drain is usually installed.

If you have several problem drainage areas you must use larger Drain Pipe if you want to connect them together  to one exit point.  Large French Drains should have their own exit point without attaching other Surface Drains or Gutters to them.  It is very common to connect too many drains or gutters into a Drainage System.  A hard rain can overwhelm the Drainage Systems Water Flow Capacity.  When that happens, water backs up and the problem area floods.

French Drain Success

Oklahoma Drainage and Sprinkler Repair

Recently we installed a French Drain that ran parallel between two houses in Moore Oklahoma.  We also installed a French Drain under a walkway to a pool in Choctaw.

French Drain walk way

French Drain Installed along and under walk way to pool.

As you can see, we installed a French Drain under the left edge of the walk way.  The stones and gravel were temporarily removed while the French Drain was installed. Then the walk way was put back on top of the French Drain.

Finished French Drain

Completed French Drain under walk way

Yesterday it rained very hard on the walkway in Choctaw.  We received a text from the home owner.

Text and photo of French Drain

 

Before we installed the French Drain, our customer told us that the walk way to the pool typically stood in 6 inches of water after even a small rain.  The water would pool on the right side and stay there for a long time after the rain had gone.  As you can see in the text pic, there is very little water standing while it is raining, and when the rain stopped, the water was gone completely.

Our customer in Moore also sent us a text as well.  He had standing water between his house and his neighbors.  His neighbor did not have any gutters which made the water problem worse.  We installed a French Drain running down the property line between the two houses.  We connected the customer’s gutters directly into the Drainage System with 4 inch gutter connections.  Had the neighbor had gutters, we would have connected them as well.  The French Drain transitioned to a solid drain pipe which ran across the front yard, under the sidewalk to the street.  We cut the curb and installed a curb outlet.

I just shake my head when I see 3 French Drains and 5 gutters connected into one exit drain pipe. I see this type of design all the time.  Why spend money for a Drainage System that won’t work?  Lots of Cheap Builders and Fly-By-Night Drainage Companies cut corners on Drainage Systems and French Drains on new home construction.

For a French Drain or a Surface Drain or any type of Drainage System,  If in doubt, use a larger Drain Pipe.  Four Inch Drain Pipe is the most common. Six inch Drain Pipe is always better.   If you are going to connect a French Drain and Surface Drain together, use 6 inch Drain Pipe.

The French Drain Trench runs through a Problem Drainage Area that needs to be drained.   The French Drain Pipe is perforated (Full of Small Holes) and has Neo-Prene Soc around the pipe.  This soc helps prevent debris from clogging the French Drain Pipe.

The dirt that was taken out to make the trench is hauled away. It is replaced by some type of small stone or gravel depending on what is desired or available. I prefer crushed 1 inch lime stone. It is the most economical option in my area. Pea Gravel or some other type of small stone can work just as well. The lime-stone or gravel is placed in the trench on top of the perforated Drain Pipe and filled all the way to the surface (ground level). In some cases where the French Drain needs to be deep or is being placed in sandy soil, a special trench liner must be placed in the trench before the perforated Drain Pipe or the Gravel are installed. This helps maintain the integrity of the trench over time. It also increases the cost of the French Drain and the amount of time to install it. I install a trench liner in a French Drain about 20% of the time. Most of the time a liner in not needed.

A French Drain is designed to handle a large volume of water and cover a large area. The Drain is anyplace the trench goes. It has many applications and can be used in many situations. It can be installed by itself or incorporated into a Drainage System with Surface Drains or Gutter Down-Spouts connected to it.

The main downfall of a French Drain is that they, for the most part aren’t very pretty. They don’t look very nice in a yard once they are completed.

French Drain Under Walk Way

Oklahoma Drainage and Sprinkler Repair recently installed a French Drain along the edge and under a Stepping Stone walkway.  The Work took place In Choctaw East of Choctaw Road.

Every time it rained, our customer had water standing on the walkway between the pool and the house.  Not only would the water stand there but it stayed there a long time.

To solve the problem, we took apart the walkway and dug a trench about 18 inches deep along the East side of the walkway.  Next we put a trench liner in the trench which is white and maintains the integrity of the drainage trench.  It allows water to pass through it but keeps sand and debris out of the perforated French Drain Pipe.  The French Drain pipe itself also has a neo preen soc and the perforated pipe as well.  This gives the French Drain Pipe two levels of protections from sand and dirt getting into the pipe.

Next, we connected a solid drain pipe to the French Drain.  It ran from the center of the French Drain perpendicularly across the walk way, down the hill 70 feet to the pop up emitter.

When digging the trench for the Drain Pipe, we carefully cut the sod in the yard and replaced it back once the drain pipe had been installed.  In a couple of weeks you won’t be able to tell that we ever dug a trench there.

Next, it was time to put the walkway back together.  The pave stones were put back into place and a nice colored gravel was put in the cracks around the walkway stones.

New Edging was also installed around the walkway.

French Drain installed in Norman

Recently  Norman Oklahoma had 4 inches of rain in two hours.  That’s the most rain in a short time that I can remember.  Storm-Water runoff can cause damage to all types of property and buildings.  Water getting inside your house is never a good thing.  A Drainage System that utilizes a French Drain can help.  Drains can protect your home and property from water damage.  Oklahoma Drainage and Sprinkler Repair installs a wide variety of Drains in many different places.  A Drain or Group of Drains with Drain Pipe going to an exit point is a “Drainage System.”

Drainage Systems can be made up of one drain or a combination of many drains.  Drainage  problems can be very complex.   Complex Drainage Problems may require a combination of several different types of drains all inter-connected and working together.  Other times the drainage problem may be simple and straight-forward requiring only one drain or several of the same type of drain connected together.

An example of a complex drainage system would be:  A French Drain in the back yard connected to a Surface Drain near a flower bed connected to several gutter downspouts, which are connected to a Channel Drain going across a driveway, which is connected to additional Surface Drain in the front yard, which runs to a Curb Fitting that lets all the water drain out on to the street.

A simple Drainage System might consist of a Surface Drain that is connected to a second Surface Drain which runs to a Pop-up Emitter which lets water drain over the curb and into the street.

An “Exit Point” is the term used for where all the water leaves the Drainage System.  Determining the Exit Point is very critical.  It is one of the first things we do when diagnosing a Drainage Problem.

Drainage Systems can:

1.  Keep water away from foundations — A French Drain is best because it can move Surface Water and Sub-Surface Water (water moving under ground) away from the foundation.  Many times less experienced companies install Surface Drains to keep water away from foundations.  This can be a big mistake.  A Surface Drain can’t move or drain Sub-Surface Water.   Also A Surface Drain often can’t move enough water fast enough and easily becomes overwhelmed during a heavy rain.  A Surface Drain also can’t cover or protect a broad enough area. Surface Drains should be designed in a Drainage System to be located in smaller Drainage Areas moving moderate amounts of water.  Surface Drains look better than French Drains.  If ,”appearance” is more important than Drainage Capacity, Go with the Surface Drain.  Just know what you are getting into and what your expectations should be. One side of a foundation alone,  can be over 100 feet.  A 4 inch or 6 inch French Drain is best when protecting a large area such as a foundation.

2.  Keep water away from small or enclosed areas.  This might be a low area just through a gate on the side of a house, or the low area between a flowerbed and the wall of a house, or standing water on or near a sidewalk or driveway.  These types of Drainage Problems are best served with Surface Drains.  A Surface Drain can move water away from a low area that is relatively small.  This can occur in yards, flowerbeds, sidewalks and driveways.  A Surface Drain is designed to move Surface Water away from a problem area to a predetermined exit point.  Surface Drains are available in many sizes.  How quickly they remove standing water is usually determined by the size of the Drain Pipe that is connected to the Drain.

Simply put, a Drainage System is one or a group of underground Drain Pipes that take water away from a place that has water standing on it or flowing across it.  The water that is in the problem area, can be causing damage or may be inconvenient or both.  (Usually Both)  A simple Drainage System is a Drain for the water to enter, a Drain Pipe to move the water away from the Drain, and an Exit Point for the water to be released out of the Drain Pipe.

Drainage Systems quickly can become more complicated.  Considerations must include:

How does the water get to the problem area?  There may be one or many sources.

Water Sources:

1.  It falls from the sky directly

2.  It flows down hill over the surface (surface water)

3.  It flows underground under the surface (sub-surface water)

4.  It flows from the edge of a roof ( There may be many roofs near the problem area, neighbors etc.)

5.  It flows from a gutter downspout

6.  It flows over the edge of a gutter because the gutter is too small is is clogged

7.  It flows up from the ground (seeps and springs are common in Oklahoma)

8.  It flows from a sprinkler system use ( yours or your neighbors)

9.  It flows from a leaking pipe ( water mains, water meters, water lines, sprinkler pipes, sprinkler valves)

There are other reasons for Drainage Problems, the above reasons are just the most common.

Once the number of water sources is determined, a rough estimate of the amount of water that needs to be drained away on average must be estimated.  This can be simplified down to “SMALL, MEDIUM, OR LARGE AMOUNTS OF WATER TO BE DRAINED AWAY.  You don’t have to be an engineer trying to calculate fluid dynamics.  Experience at diagnosing drainage problems helps however.  How much water needs to be moved will help determine the type and size of the Surface Drain or French Drain that needs to be installed.  It also helps to determine the size of Drain Pipe required for the Drainage System.  A good rule to follow is, “If in doubt, install a larger Drain and Drain Pipe.”  Unused Drainage Capacity is better than property damage caused by a Drain that is overwhelmed by too much water.

For home and small business use typical materials used are:


A “French Drain” Moves “surface water” away from a low lying problem drainage area.  Sub surface water is many times not considered or thought about when a drainage system is being installed.  People only think about what they can see and don’t think much about what they can’t see.

Sub Surface water is water that is underground and saturated in the soil.  Just like water above ground (Surface Water) moves.  Water under ground moves too and is a very big part of any drainage problem.

Water flows over the surface into the area that floods and is a problem.  A big mistake that is made be the casual eye, is that all the water in a swampy problem area got there by running over the surface.  Yes, it probably did, but it also got there by moving there underground as well.  This is called SUB SURFACE WATER MOVEMENT, and it is important to any kind of Drainage System that might be installed.

If your problem water is partially Sub-Surface water, and you install a Drainage System that uses Surface Drains only, then you just wasted a lot of money!

Water can only be drained away that is on the surface.  It goes into the top of the Drain on the Surface.  It’s Name is ” A Surface Drain.”  It Drains Surface Water ONLY!

A French Drain can drain Surface water and Sub Surface water both.  It water is in the problem area by means of Sub – Surface movement, then it will enter the French Drain Laterally, under ground,  and be drained away along with the surface water.

Surface Drains look nice but they have limited applications.  They must be installed in situations that they are designed for.  Surface Water only in smaller volume applications.  Surface Drains don’t move as much water as French Drains.
