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.

Points to note if you are looking for the planter drainage system:

• Terrain and drainage outlet profiles
