Oklahoma Drainage : 405-203-9419

Surface Drains Installed in Driveway.

We also install Channel Drains in sidewalks and driveways.  Many types and styles are available.

 

 

 

All Drainage Systems needs to have an exit point.  The water needs a place to go.  Oklahoma Drainage  installs cement curb outlets as one possible exit.  There are several other possibilities.

Oklahoma Drainage can install a very simple drain or a complex 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.

French Drain Installation can be tricky sometimes.  Recently we installed a French Drain in Norman with very little “Fall”.  This means that the “Intake” For the Drainage System is close to the same level as the “Exit.”  Simply Put, it is hard to make a Drain work if it isn’t ” Down Hill,” to where the water is going.

This was the Situation for the French Drain we installed last week in Norman.  The standing water was in the back yard.  There was only one direction that we could take the unwanted water to drain away.  In this case it was only slightly down hill.  The French Drain was installed at a shallow level in the back yard.  The solid drain pipe that was attached ran from the back yard, along the side of the house to a curb outlet at the street.

As the trench for the Drain Pipe was dug, it had to start shallow and slowly get slightly deeper as it approached the street.  This was an absolute Precision Job.  The trench could not be even an inch too deep or too shallow along its course.

At the street, a “Pop-Up” Emitter could not be used.  It would cause the water to stop flowing.  Two Install a Pop-up Emitter at the Exit of any Drainage System,  There must be at least 6 inches of “Fall” from the Drain to the Exit.

In Our Case, we only had 3 inches of fall to work with.

The solution was to Cut the curb and Install a Curb Outlet.

This process involves cutting the Curb with a concrete saw and placing a rectangular Curb outlet in the empty space.  We then put acrylic concrete around the outlet to make it look nice.

The fact that the outlet is square or rectangular is very important.

Many times I look at Round Curb outlets installed by my competitors and just shake my head!  This is a mistake.  Round Curb outlets are bad when the Drainage System is at Max Capacity and the pipe is completely full.  Air needs to be able to get into the pipe at the curb to ensure that the Drainage System can work at its Max.

The Drain will work with a Round Outlet, Just not very well.

Have you ever tried to Pour liquid out of a Jug or 2 liter bottle holding it completely upside down?

It Drains and Stops and Starts as the liquid comes out.  “It Chugs” and struggles to get air up inside the hole.  It doesn’t work very well.

A Square Outlet allows air to constantly flow into the top corners of the Curb Outlet.

As a result, Much more water is moved in the same size pipe.
