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.
