Different types of surface water drainage, such as manholes and French drains, are available for personal and commercial use. French drains are inexpensive, unobtrusive, and effective at preventing erosion and floods. They consist of a gravel trench with a drilled pipe that redirects water to a drainage outlet. Manhole covers are common in cities and suburbs and can catch more water than French drains. Proper water drainage is crucial in preventing property damage and controlling floods.
There are many different types of surface water drainage available for both personal and commercial use. Typically, the most common types of surface water drainage systems are manholes and French drains. French drains are primarily used in applications involving small amounts of water, while storm drains are intended to redirect and distribute large amounts of water. Whichever drainage system you employ, however, depends entirely on the type of property, its weather patterns and the time and money you want to invest in installing it.
Surface water drainage can be very beneficial, especially for areas that receive copious amounts of annual rainfall. Keeping certain areas of land free of excess water can help prevent erosion, which can cause major property damage. Not only that, but drainage systems also help prevent and control floods. In fact, one of the most common causes of flooding is improper water drainage.
One of the most commonly used surface water drainage systems is the French drain. In addition to effectively draining water, french drains offer an incredibly wide variety of benefits. They are very inexpensive to install and maintain, making it very possible for the average homeowner to install a french drain system themselves. Along with that, their underground placement makes them incredibly unobtrusive and, in some cases, aesthetically appealing.
French drains are best installed at the bottom of a slope. Basically, French drainage consists of a gravel or stone trench, with a drilled pipe buried underneath. The gravel or stone serves as a way to catch flowing water while also redirecting the water to a drilled pipe. This works because there is space between each piece of gravel or stone, allowing an area for water to travel. The water flows to the bottom of the trench, where it enters through holes in a drilled pipe.
The hose then redirects the water to a drainage outlet. A drain plug can be installed in a variety of locations, such as larger bodies of water or artificial reservoirs. In many applications, the nearest paved road or unoccupied area is used as the drain.
Another surface water drainage system is a manhole cover. Manhole covers are common and are mostly found on the streets of cities and suburbs. These can catch more water than a French drain due to their wider, grate opening. Water is often redirected into stormwater drains using channels or the natural slope of a road or street. Water entering a drain travels through an underground concrete pipe and into a larger body of water.
