What are different types of drainage system? Which among is most common type of drainage system
Answers
Swale Drains
APPEARANCE
Swale drains are, in essence, a shallow ditch lined with turf grass or similar vegetation. They are a broader and more shallow system, which makes them more subtle than traditional trench-style systems.
Point Drains

APPEARANCE
This is a subsurface system that requires floors to be sloped in the direction of the drain. When multiple drains are needed, this can create an unattractive, unleveled appearance and result in difficulties in planning and setting up the facility.
French Drain
APPEARANCE
It is a subsurface structure that consists of a perforated pipe that is installed flat in a yard with a sloped trench that helps move water runoff from a highest point at the start to the lowest at the end, where it goes into a sewer, cistern, or swale
Trench Drains
There are many different types of drainage systems that fall under the “trench drain” umbrella, from the standard trench drain to more specific kinds.
APPEARANCE
Unlike other systems on the list, trench drains are a surface system. In essence, a trench drain consists of a large trench that has a drain channel set in place with concrete. This channel can be very narrow or very wide and is usually covered with a heavy metal grate.
HDPE Drains
High-density polyethylene trench drains are a newer innovation in terms of drainage systems that have become popular.
APPEARANCE
These systems have pre-engineered, modular channel sections that are lightweight and easy to install. They are smooth in texture and highly durable as well. Like with tradition trench drains, HDPE systems still require a grate cover
Cast-In-Place Trench Drains
APPEARANCE
Of all the different types of drainage systems, this one can be most problematic. To install, a trench is dug, then wood forms are put in place with a reinforcing bar before the casting the trench with concrete. Like other trench systems discussed thus far, this one also requires a grate coverings
Slot Drain
Finally, in looking at the different types of drainage systems, there is the newer and more innovative type of trench drain called the Slot Drain.
APPEARANCE
The Slot Drain’s appearance is unique when compared to other systems because it comes as a pre-sloped and pre-assembled single piece of surface drainage. Unlike other types of trench drains, the Slot Drain has a slimmer design which eliminates the need for a grate covering. It comes with different material options, including a popular and durable food-grade stainless
