A French drain collects rainwater and allows it to drain smoothly. They are installed in houses and on roads.
Rainwater troughs are broadly divided into two categories: those that channel rainwater collected on the roofs of houses and those that channel water collected on roads.
In addition, there are two types of systems used in French drain systems: infiltration and non-infiltration. Some municipalities provide subsidies to promote the installation of infiltration-type French drain, but there are some areas where it is not possible to install infiltration-type rainwater troughs.
French drains are found in many places, from ordinary homes to commercial facilities, and parks.
As a measure to prevent flooding damage in urban areas, rainwater storage facilities are being installed to control rainwater runoff.
Depending on the location and application, French drains are installed with various functions. Although French drains are widely used in ordinary households, regular maintenance is required to maintain their functionality and ensure their comfortable use.
Ponding water can cause mosquitoes in the summer. Mud buildup can also make it difficult for water to flow.
There are two types of French drains: permeable and non-permeable. The permeable type has holes in the sides of the French drain to allow water to soak into the ground and be treated. Non-permeable rainwater troughs are connected to pipes so that water can flow to the sewage system.
With infiltration-type French drains, the amount of water that percolates into the ground can be controlled by the way the trout and infiltration pipes are connected. For this reason, PVC pipe French drains are often used, as they are easy to lay out and handle.
The advantage of infiltration-type French drains are that they can reduce flood damage from heavy rains. They also help protect water resources. For safety reasons, infiltration-type French drains cannot be used where the groundwater table is high or on steep slopes.
Vinyl chloride, concrete, and other materials are used for French drains, but vinyl chloride is most often used. They are lightweight and easy to handle and install. Because they are compact and easy to connect to drainpipes, they are said to be easy to install even in ordinary homes where space for burial is limited.
