Drainage Systems take water from a drainage problem area through a Drain Pipe  where it then is released through an exit point such as a Curb Fitting or Pop-Up Emitter

.  The Water enters the drain pipe through some type of drain.  Drains that take in water in a Drainage System are of the Surface Drain type which has a Grate on top of some type or size of basin. Or French Drain Style which absorb water through gravel above a perforated Drain Pipe.

Standard Surface Drains are 6 inch, 9 inch and 12 inch.  Each size Drain may have a Square or round Grate sitting on top of a drain basin which is connected to a drain pipe.

The size of the Drain Basin and the size of the Drain pipe dictate how much water can be moved and how fast drainage can take place. A larger Drain Pipe is always a better choice.  A 12 inch Drain Basin with a grate connected to an exit point with six inch Drain pipe move much more water than the same  system with only 4 inch Drain Pipe. The 6 inch Drain Pipe moves many times more water than 3 inch or 2 inch Drain Pipe.   Larger Drain Basins take more water into a Drainage System as well.   French Drains always take in more water faster than Surface Drain.  A 4 inch French Drain will take in and move a much higher volume of water than a 4 inch Surface Drain.

Key Points — French Drains move more water than surface Drains.

Larger Drain Pipe move more water than Smaller Drain Pipe

Using large Drain Pipes with A French Drain System moves the most water of all

Using 2 or more Exit points for the Drainage System increases Drainage Capacity.

Drainage Systems are not Flood Prevention Systems.  If Flooding allows flood water to rise above the exit point of a Drainage System, water will not drain away because the exit point is under water.  An exit Point that is way down hill from the drainage system ensures drainage under most all situations.  As long as the water has a place to drain to the drainage system will function correctly.

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 inclosed 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.

Don’t let standing water or storm water run-off damage your home!  CMG Sprinklers and Drains can help with Drainage Problems in and around your home or business.  If you have water standing in the wrong place after a hard rain, a Drainage System can be a great solution!  If your sidewalk turns into a moat after a storm, or if your back yard floods from run-off from your neighbor’s roof give CMG a call.  CMG can quickly diagnose your Drainage Problems and provide a solution.  We incorporate several types of Drains in our Drainage System depending on the Drainage Problem.  CMG installs:  French Drain, Surface Drain, Channel Drains, Basin Drains, Trench Drains, and Sump pumps.We install Drains in lots of places including, Yards, Flower Beds, Driveways, Sidewalks, and next to Swimming Pools.

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

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.

Surface Drain and Drain Pipe

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.

French Drain March 2011
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.

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:

6 inch, 9 inch, and 12 inch Surface Drains

3 inch, 4 inch, and 6 inch Drain Pipes

3 inch, 4 inch, and 6 inch French Drains

French Drains move more water than Surface Drains —

French Drains move Surface Water and Sub-Surface Water

Surface Drains move Surface Water only

Surface Drains look nicer than French Drains in most cases

Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?)

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

Harsh weather in Oklahoma seems to becoming more common.  In 2013,  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.  CMG 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 System installation and design is a big part of our business.  Does your sidewalk turn into a moat after a hard rain?  Does part of your yard look like a pond after a thunderstorm?  Worst of all, are you experiencing concrete deterioration to your foundation, sidewalk, or driveway CMG can design a Drainage System to solve your Drainage Problems Our Drainage Systems can be simple or complex.  We utilize, French Drains, Surface Drains, Channel Drains, Basin Drains, Basement Drains, Trench Drains, and Sump Pumps.  Estimates are free

Water Seeping Into your house? You need a French Drain!

Do you have water seeping into your floor vents after a hard rain?  Is water causing damage to your floors or carpet?  Is water finding a way under your foundation after a thunder storm?  CMG Sprinklers designs and installs Drainage Systems that can help stop the damage.  We utilize:  French Drains, Surface Drains, Channel Drains, and Sump Pumps to protect property.  Connecting gutter-downspouts into the Drainage System is always a good idea where possible. The need for Drainage Systems is increasing in Oklahoma.  During heavy thunder storms,   homes and business need a way to drain water away Storm water can cause many kinds of damage.  Here are just a few: 1.  Driveways and Sidewalks can crack and deteriorate 2.  Foundations can crack move or shift 3.  Vents and ducts can fill with water 4.  Mold can be allowed to grow 5.  Trees and Plants and grass can be damaged or drown Too much water is never a good thing! CMG can quickly diagnose your Drainage Problem and provide a free quote for a Drainage System.  With twenty years of experience, we realize that Drainage Problems may be very complex and difficult or very straight forward and simple.  Every Drainage Problem is unique to a certain degree.  Don’t kid yourself,  Experience Counts! CMG 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)

These are just a few of the considerations for any Drainage System Diagnostic.

The Drainage System shown in the three above pictures consisted of the following: Three Gutter Downspouts in the front yard were connected to 4 inch ADS solid Drain Pipe with Large Drainage Gutter Connections.  Three lateral 4 inch Pipes were run from each gutter to one outflow pipe moving the water to two exit Pop Up Emitters. One of the Drain Pipes ran under the sidewalk to reach the Exit Drain Pipe. This Drainage System had two exit points.  One Pop-Up Emitter was on the edge of the driveway in the front yard.  The other Pop-Up Emitter was installed in the back yard near the property line.  Two exit points allows for a much larger Water Drainage Capacity.  (During Heavy Rains The Drainage System Can Move More Water Faster) The back yard Exit Pipe then connected to 55 feet of 4 inch French Drain that was installed along the SW corner of the house.  The French Drain provided a protective barrier for that room of the house where water had previously been leaking into the floor vents.  Two Gutter Down Spouts were also connected in the back yard to the Drainage System.

A few days later a heavy rain came in.  No water stood on the sidewalk near the front door, and nor water seeped into the floor vents in the back bedroom. CMG works closely with our customers.    We provide all the information we can to help the customer make a decision that will solve their Drainage Problem. Typically,  Drainage Systems are made up of one or several types of Drains.  CMG utilizes French Drains, Surface Drains and Trench Drains when designing Drainage Systems.    There are many types and sizes of Surface Drains and French Drains.  Again, experience is the key! If you have water standing on your driveway after a hard rain.  If your plants and trees are under water because your neighbor just added new gutters.   If your sidewalk is cracking  because half the time it is under water.  Give CMG a Call!  405-226-0629 CMG Sprinklers and Drains 405-226-0629 Check Out Our Other Sites! cmgsprinklersanddrains.com cmgsprinklersandrains.blogspot.com btnbusinessblog.wordpress.com activerain.com/blanecallen blanecallen.wordpress.com

French Drains, Drainage System, Surface Drains, Oklahoma City, Norman, Edmond, Mustang.

In the past 20 years, CMG has designed and installed a large number of Drainage Systems.  For the most part, we have utilized French Drains and Surface Drains of many different shapes and sizes.  In two decades we have built up a high level of experience diagnosing Drainage Problems.  We know what to look for, what to expect, and how to approach a wide variety of situations where water is in a harmful or undesirable place.

CMG Sprinklers and Drains installs many types of Drains in a wide variety of places.  Here are a few of them. French Drain Installation along foundations near walls French Drain Installation behind retaining walls – French Drain Installation in and around flower beds – French Drain Installation in basements – French Drain Installation near sidewalks and along driveways – French Drain Installation under pool decks and around swimming pools – French Drain Installation on hillsides and on slopes to protect building and homes – Surface Drain Installation in sidewalks set in concrete – Surface Drain Installation in driveway set in concrete – Surface Drain Installation on side of house to catch water from gutter downspout Surface Drain Installation in basement with Sump Pump inside to pump out the water Surface Drain Installation in low spot in yard to handle a moderate amount of water – Surface Drain Installation next to driveway to catch water run-off – Surface Drain Installation next to sidewalk to catch water run-off – Surface Drain Installation connected to gutter down-spout – Just what is a “French Drain?”  Many times people incorrectly 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. A Surface Drain may come in many different shapes or sizes.  It is a Drain Basin with a Drain Grate on top and a Drain Pipe connected on the side.  The Drain Grate may be round or square.

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.  It is long and narrow with a grate on top.

Channel Drain installed in a sidewalk by a front door.
Channel Drain installed in a sidewalk by a front door.

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.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   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. A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes of French Drain Pipe.   Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is 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.

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 inclosed 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 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: 6 inch, 9 inch, and 12 inch Surface Drains – 3 inch, 4 inch, and 6 inch Drain Pipes — 3 inch, 4 inch, and 6 inch French DrainsFrench Drains move more water than Surface Drains — French Drains move Surface Water and Sub-Surface Water Surface Drains move Surface Water only Surface Drains look nicer than French Drains in most cases Once the type and number of drains is determined and what size Drain Pipe will connect them, an exit point must be selected.  (Where is the Drainage System going to take the water to and release it?) The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.DSC00560

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

Drainage System installation and design is a big part of our business.  Does your sidewalk turn into a moat after a hard rain?  Does part of your yard look like a pond after a thunderstorm?  Worst of all, are you experiencing concrete deterioration to your foundation, sidewalk, or driveway CMG can design a Drainage System to solve your Drainage Problems Our Drainage Systems can be simple or complex.  We utilize, French Drains, Surface Drains, Channel Drains, Basin Drains, Basement Drains, Trench Drains, and Sump Pumps.  Estimates are free!

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

A Surface Drain may come in many different shapes or sizes.  It is a Drain Basin with a Drain Grate on top and a Drain Pipe connected on the side.  The Drain Grate may be round or square.

A Channel Drain is a type of Surface Drain and many times is installed in concrete across sidewalks or driveways.  It is long and narrow with a grate on top.

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.  A  Trench Liner is sometimes used depending on the Drainage System Design and the type of soil.   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.

A trench is dug that is slightly wider than the French Drain Pipe that is being used.  There are several sizes.  Three Inch, Four Inch, and Six Inch are the most common sizes of French drain Pipe. The dirt that is 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.

French Drain Exit Points, Curb Fittings, Pop-Up Emitters, Oklahoma City, Edmond, Moore.

Drainage Systems can be made up of several types of Drains including French Drains, Surface Drains, or Channel Drains.  The following information focuses on Drainage System Exit Points CMG Sprinkler and Drains uses Curb Fittings or Pop-Up Emitters.

French Drains can be used in a variety of places and situations.  Typically a French Drain is intended to move a large volume of standing water away from the Problem Drainage Area to a predetermined exit point.  Once the standing water enters the French Drain, it flows downhill to the exit point.  The water is then released at the exit point by a Drainage Curb Fitting or a Drainage Pop-Up Emitter.

The Drainage Curb Fitting is installed when the desired exit point for the French Drain will release the Drainage Water into the Street.   The Drainage Curb Fitting is rectangular in shape and made to be installed through the curb.  A small section of Curb is cut out with a concrete saw.  The Section is a few inches wider than the Drainage Curb Fitting.  We then install new concrete around the curb fitting.  Once the concrete has dried, the Drain Pipe coming from a French Drain or Surface Drain is connected to the Drainage Curb fitting and then covered with dirt.

The Drainage Pop-Up Emitter is connected to the end of a Drain Pipe.  It is downhill from a French Drain or a Surface Drain.  It is a small release basin with a green pop-up lid.  When releasing water, it pops up about an inch to release the water from the French Drain or Surface Drain.  When the Storm Water has moved through the Drainage System and out of the Pop-Up Emitter, the green lid closes back to its original closed position.  The emitter is designed to release water out into a yard or down a hill or other desirable Drainage Exit Point where there is no curb.

Drainage Problems, French Drains, Surface, Drains, Oklahoma City, Norman, Edmond.

The need for Drainage Systems is increasing in Oklahoma.  During heavy thunder storms,   homes and business need a way to drain water awayStorm water can cause many kinds of damage.  Here are just a few:

1.  Driveways and Sidewalks can crack and deteriorate

2.  Foundations can crack move or shift

3.  Vents and ducts can fill with water

4.  Mold can be allowed to grow

5.  Trees and Plants and grass can be damaged or drown

Too much water is never a good thing!

CMG can quickly diagnose your Drainage Problem and provide a free quote for a Drainage System.  With twenty years of experience, we realize that Drainage Problems may be very complex and difficult or very straight forward and simple.  Every Drainage Problem is unique to a certain degree.  Don’t kid yourself,  Experience Counts!

CMG 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)

These are just a few of the considerations for any Drainage System Diagnostic.

The Drainage System shown in the three above pictures consisted of the following:

Three Gutter Downspouts in the front yard were connected to 4 inch ADS solid Drain Pipe with Large Drainage Gutter Connections.  Three lateral 4 inch  Drain Pipes were run from each gutter to one outflow pipe moving the water to two exit Pop Up Emitters. One of the Drain Pipes ran under the sidewalk to reach the Exit Drain Pipe.

This Drainage System had two exit points.  One Pop-Up Emitter was on the edge of the driveway in the front yard.  The other Pop-Up Emitter was installed in the back yard near the property line.  Two exit points allows for a much larger Water Drainage Capacity.  (During Heavy Rains The Drainage System Can Move More Water Faster)

The back yard Exit Pipe then connected to 55 feet of 4 inch French Drain that was installed along the SW corner of the house.  The French Drain provided a protective barrier for that room of the house where water had previously been leaking into the floor vents.  Two Gutter Down Spouts were also connected in the back yard to the Drainage System.

A few days later a heavy rain came in.  No water stood on the sidewalk near the front door, and nor water seeped into the floor vents in the back bedroom.

CMG works closely with our customers.    We provide all the information we can to help the customer make a decision that will solve their Drainage Problem.

Typically,  Drainage Systems are made up of one or several types of Drains.  CMG utilizes French Drains, Surface Drains and Trench Drains when designing Drainage Systems.    There are many types and sizes of Surface Drains and French Drains.  Again, experience is the key!

If you have water standing on your driveway after a hard rain.  If your plants and trees are under water because your neighbor just added new gutters.   If your sidewalk is cracking  because half the time it is under water.  Give CMG a Call!  405-226-0629
