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.

French Drain Information

Edmond Oklahoma has been the location for many French Drain Installations for us in the past several years.  Recently we ripped out an old Surface Drain that was under a deck.

The Surface Drain was too small for the job and did not Protect the Foundation from Standing Water.

The First step was to take out part of the deck along the wall.

Next, we took out the Surface Drain and the Three-Inch Pipe which was too small.  Digging a trench along the foundation came next.  We had to ensure the “Fall” to make sure the water would run from left to right.   A French Drain Liner needed to be installed.  This was necessary to maintain the integrity of the trench and to keep the French Drainpipe from filling up with sand and getting clogged over the next few years.

We then installed 4-inch ADS Perf/Soc French Drainpipe along the course of the French Drain.  Next, we connected the end of the French Drain Pipe to Solid 4 Inch ADS Drainpipe to continue along the trench to the Pop-Up Emitter at the Exit Point.

Oklahoma Drainage

takes many things into account when providing a Drainage Diagnostic for a Customer.  We determine:

1.  What is the Primary Water Source to the problem?  Where is the water coming from?

2.  Is there a Secondary Water Source?  Other Places that water may be coming from.    All Drainage Problems have more than one source!

3.  How many Subsequent Water Sources are present?   Some complex Drainage Problems have many water sources.

4.  What exit points are available for gravity to move water away from the problem area?  Where are we trying to take the water to, and how is it

going to be released?  Is more than one exit point possible to increase capacity?

5   How much water must be moved?  What Size Drain Pipe is necessary to lessen the chance of being overwhelmed by flooding?    This is a tough

consideration.  (Larger Pipe – Larger Cost to Install)

FRENCH DRAIN OR SURFACE DRAIN?

When Determining what type of Drain you need for your Drainage System.  In our last blog, we talked about Surface Water and Sub-Surface water and why you need to understand them before designing your Drainage System.  If you need to review, click below.  If you have a question or comment please leave it at the bottom of the page. I will respond as quickly as I can.

Before we get into Water Movement, we need to discuss Surface Drains.

Surface Drains come in many shapes and sizes.  The two most common are Basin Drains and Channel Drains.

A Basin Drain has a Square Grate and it sits on top of a catch basin.  It will have a single pipe connected to it or it will have a drain pipe running into it and a pipe running out of it.  We used this picture in a previous blog, but I want to show it to you again.

Surface Drain Connection

Surface Drain connected to a Transition Pipe

Below is a Basin before the pipe is connected to both sides.  The pipe is cut and connected to one side.   Another piece of Drain Pipe is connected to the other side.  The Drain pipe does not run straight through the basin.  Water must have a way to enter the Drain Pipe.  The Surface Drain in the picture is the most common size used in residential applications.  The Drain Pipe connecting to it is 4 inch ADS Solid Drain Pipe.

For a Surface Drain to work well it must be placed in a low lying area of standing water.  It is not intended to intercept moving water or to drain away Sub-Surface water.

 

In review, detecting Surface Water is straight forward.  You can observe how it flows into the Problem Drainage Area.

Sub-Surface water is not so easy.  You can’t see it move into the problem area.  So What do you do?

First take a look at your soil.  What type of soil do you have?

Soil with a lot of clay will have less Sub-Surface Water, Maybe none at all.  If you do have some it will move into the area slowly.  If you have sandy soil the underground water will move there in a hurry.  Most people will have something in between.

To be sure, a few simple tests can help.

Next check the problem drainage area when there is no water standing in it.  Is it soft and mushy when the surrounding area is more firm?  This is an indication that Sub-Surface Water is still flowing into the area.  Another way to collect information is to dig a small hole about a foot deep in the area. Check it every day for several days.  If water is standing in the hole, you have a Sub-Surface Water issue.  How fast it flows into the hole is also important.

OK, you have Sub-Surface water along with Surface Water in your problem drainage area.  Your Choice for the correct “Intake” for your Drainage System should be a French Drain.

OK, You have no Sub-Surface water. You only have Surface Water flowing into the problem area.  You need a French Drain If you are trying to intercept the water as it comes into the area.  Many times water will run around the surface drain and still flood the area.  Also the Surface Drain is much more easily overwhelmed and water will run past it that way too.  Again, this is very important,  If you are trying to intercept water before it gets to where its going, don’t use a Surface Drain.

A Surface Drain should be used in a Medium to Low Volume Water situation.  The water needs to be stationary or moving very slowly.  It should be placed in an area that is the lowest point in the Problem Drainage area.  They also work well in smaller confined areas such as pool decks, along sidewalks, or in flower beds.

More than one Surface Drain can be connected to one drain pipe in a “Daisy Chain” of Drains if you have several low spots in a larger area.

In many cases a small french drain can be installed in almost every place that a Surface Drain might be installed.  People opt for a Surface Drain over a French Drain because they like the way the Surface Drain looks more than the way the French Drain looks.  For some People, Looks are more important than functionality.

Channel Drains are set in concrete or dirt but dirt is not always the best idea.  Setting a channel drain in dirt should only be done when a shallow surface drain is needed and that is the only option.

Setting a Surface Drain in Concrete such as a driveway or a Sidewalk is a good application for a Surface Drain.  Many times it is better to install a French Drain in your yard over a Surface Drain.  What ever makes you happy!

French Drains can be made to look very decorative.

French Drains can be decorated with many types of stone

In conclusions,

French Drains are used for :  1.  Higher water volume situations  2.  Intercepting moving Surface Water  3.  Solving Sub-Surface water problems

Surface Drains are used for: 1.  Smaller water volume situations  2.  Standing Surface Water that has reached its destination   3.  Smaller and more confined areas  4.  Set in concrete such as sidewalks or Driveways

French Drains are Perforated Pipe in a Drainage Trench with the dirt removed.  Gravel is then placed surrounding and on top of the French Drain Pipe.  Typically French Drains For Residential and Small business applications have perforated pipe that is 3 Inch, 4 Inch or 6 inch.  The larger the pipe the more water your Drainage System can handle.

I personally believe that ADS French Drain Pipe is very good.  Pvc French Drain pipe is very bad.  I have made a very good living replacing PVc French Drain Pipe with ADS French Drain Pipe.

ADS holds up over time much better.  It has a Neoprene Sock around the perforated pipe that keeps dirt from clogging the drain pipe over time.  PVc French Drain Pipe becomes brittle and cracks and deteriorates in only a few years.  It will not have a “soc” around either.  If you are not sure which one is which, Ads is Black and Pvc is white.  The choice is yours.

Anyway, Sorry! i’ll step off my soap box.

Large 6 Inch French Drain

A French Drain is designed to move a large amount of water in a large area such as a yard, flower bed or on the side of a house.   They are installed in dirt and are covered with some type of crushed stone or gravel.  A trench that a French Drain is going to be installed in looks like this.

A Trench Liner can be installed in the trench as well.   It is cloth that is designed to go in the empty trench before the Perforated Pipe and the Gravel is installed.  The Trench liner can be found at most retail drainage outlets.  If you can’t find any, ” Weed Matt” in the garden section that goes in flower beds works very well.

A trench liner will increase the cost of a French Drain.  Many times they are not necessary.  Sometimes they are very necessary.

A Trench Liner will maintain the integrity of the Drainage Trench over time.  But, If you have a “Sub Surface Water Problem they may impede how well your French Drain Works.

Don’t worry, It will make more sense as you read this blog and ones that follow.

A completed French Drain looks like this.

Moving a large volume of water is not the only reason to install a French Drain.

When Diagnosing a Drainage Problem, the first thing to consider is how does the water get into the Problem Drainage Area.  The most obvious way is by flowing over the top of the ground.  This is called “Surface Water.”  Water comes from somewhere else by flowing over the ground.

I know that’s overly simple but right now its necessary.

French Drains do a Great Job in moving Surface Water away from the flooded area.  For example, the water flows out of my neighbors yard, down the hill and into mine.  It then runs into my French Drain, Then into the drain pipe, it then moves through the drain pipe to the exit point at the curb outlet  and into the street.

( Simple Enough)  Ahh, but there is more!

The thing that people miss, don’t anticipate, and don’t understand, is “Sub-Surface Water.”  Sub-surface water is not accounted for many times, in the design of a Drainage System.

OK, Think about the example above again, only this time the water is flowing underground as well as over the surface.  So, in fact, you have at least two sources of water feeding your Drainage Problem Area.

Why is that important?

Surface Drains are not designed to move “Sub-Surface Water.”  Just as the name says, Surface Drains move Surface Water.

Many times a Surface Drain is installed out in a yard to solve a drainage problem instead of a French Drain.

Surface Drain Connection

Don’t get me wrong, Surface Drains are great!  I have installed literally thousands of them since 1993.  They do an awesome job when they are installed for the right reasons.  Problem is they do absolutely nothing to drain “Sub Surface Water”.  In later blogs we will discuss the correct application of a Surface Drain.

Back to the French Drain.  A French Drain can take in water topically. ( In the top of the drain) It also can take water in Laterally. ( Through the Sides underground)

So you must determine before installing a Drainage System,  how the water gets into the problem drainage area.

Is it Surface Water?  Sub-Surface water? Or Both?  Our next blog will discuss this.

A French Drain is just a part of a Drainage System.  Many people refer to basically any type of Drain in or around their home as a French Drain.  This actually in not correct.

Gutter to French Drain

Connecting Gutter to French Drain

Before you can really understand what a French Drain is, you first must be familiar with a Drainage System and what it involves.

Intake

A Drainage System has three parts.  It has an “Intake” to bring water into the Drainage System.  It is placed in a low area where water is standing or is in area where water sometimes runs across it over the surface or under the surface or both.  An “Intake” will be a French Drain, Surface Drain or Sump Pump.

In a Simple Drainage System there will only be One “Intake.”  In a Complex Drainage System there will be several Intakes.  They may vary in type and size.  For Example, You may have a Drainage System with a Surface Drain, and a French Drain and a Sump Pump all as separate  Intakes in the Drainage System.  The Intakes will vary in number and type depending on what water issues you are trying to fix.

Transition

The “Transition” is the second part of the Drainage System which is the Drainpipe that moves the water out of the area that is flooded.  It is your water “High Way, ” as it were.  Typically there are two types of Transition Drainpipes that will be covered later.

Exit

Finally you have an “Exit” which releases the water from the drainage system.  It must be in an area that is lower than the French Drain or Surface Drain that is you “Intake.”

Perforated Pipe

A French Drain  is a perforated pipe that is basically full of slits or holes.  A trench is dug across the problem drainage area.  The dirt from the trench is hauled away.  The perforated pipe is placed in the trench.  The Drainage trench is dug deep enough so that the perforated French Drainpipe is several inches below ground level when placed in the trench.  Next gravel or some type of crushed stone is placed on top and around the French Drain perforated pipe until the trench is full.

 

Once a French Drain is completed you will see gravel on the surface in a place where dirt use to be.

Large Amount of Water

A French Drain is designed to take in and move a large amount of water.  It covers a large area with water standing on or moving across the area.  It needs to have some “Slope” or “Fall” to drain the water.  The pipe needs to run down hill to the exit point to release it from the Drainage System.  If it is up hill in all directions from the French Drain then there is a problem.  We all know that water will not flow up hill.  Some times this can be overcome when it is only slightly up hill by digging the trench deeper as you go up hill.  Still the exit point in the Drainage System must be lower than the French Drain where the water is taken into the drainage system, or the water will never drain.

In conclusion, a French Drain is a perforated Pipe in a trench covered in gravel.  It is the “Intake” part of a Drainage System.  It covers a wide area and needs to be higher than the exit point of the Drainage System.

This is the first in a series of blogs about French Drains and all other types of Drains as well.  If you would like to learn more just Click on the “Next Blog” below.

Recently Oklahoma Drainage and Sprinkler Repair Installed a French Drain as part of a Drainage System in Mid West City Oklahoma.

Our customer had a back porch Sun Room.  Every time he had a hard rain, Water would run in one door and out the other.  An indoor creek across his Sun Room.

We installed a French Drain in front of the South Door.  It was 26 feet long and ran from a gutter downspout which it was connected to,  in front of the South Door and along the house covering the entire “Low” Area.  Then we connected 4 inch ADS Solid Drain pipe to the French Drain and ran down hill around the corner of the house to the street.

Once the 4 inch solid drain pipe was connected to the French Drain and the two gutter down spouts, a pop-up emitter was installed to release the water at the street.

The next step was to cover the drain pipe with dirt and put the sod back in place on top of the pipe.   There was about 8 wheelbarrows of dirt left over that was displaced by the drain pipe and the French Drain.  The extra dirt was scooped up and hauled away.

While installing the drainage system, it was necessary to move two sprinkler heads that were in the way of the drain pipe installation.  This was no problem.  Installing drainage systems and French drains for folks who have a sprinkler system is very common.  Moving Sprinkler heads or pipes sometimes is necessary.  We always leave the sprinkler system in complete working order and we discuss any changes in the sprinkler system with the customer before we do it to make sure that everyone is on the same page.  In most cases the customer cant tell that we made any changes to the sprinkler system at all.
