Planter Drainage System

The drainage system is an important and essential component in the landscaping work but is commonly being neglected and overlooked. Waterlogged soil could lead to root rotting due to insufficient oxygen and toxicants from anaerobic environment. Plants wither eventually if the planter drainage is poorly designed or constructed. The planter drainage system is formed by solid pipeline, outlet, weep hole, perforated pipe, geotextile or drainage aggregate to properly dispose of the excess water from your yard and allows the plants to grow healthy. Drainagepipelines and stormwater intake are installed in different shapes according to the site situation, such as branch shape, circular shape and fish bone shape. It shall be installed to direct the water from high level to the final outlets. Common types of drainage system are as below:
Terrain drainage
By forming the 0.1% to 0.3% inclination on the ground surface, the terrain drainage ensures water discharging to the river, lake or drain pit. The installation cost of terrain drainage is low and there is no separate drainage system. It is commonly adopted in civil works and building works.
Open Channel
The water in the low-lying topography is directed to the drainage outlets by open trenches on the ground. This method is utilized in area where fast discharge is required and in area with uneven terrain. Sometimes, open channel is even adopted in emergency discharge of flooding water. Dimension of open channel is depended on the discharge volume. Inclination of the channel is normally designed to be at least 0.2% to 0.5%.
Pipelines
By underground pipeline or canal, water is discharged away from planters and from low-lying topography. This method is aesthetically tidy and is commonly used in buildings and urban cities. But it is high in installation and maintenance costs.
