When choosing a grated trench drain, the following factors should be considered:

• Hydraulic Performance - how much liquid is to be collected and removed.
• Application - the issues relating to location of the drain.

These factors should be addressed regardless of whether a modular channel system or cast-in-situ grated trench is used.

Hydraulic Performance

The volume of liquid the grated trench drain collects and carries in a given time period.

Application
2a) Loading

Loading refers to any foot or vehicular traffic being applied to the grated trench drain. Load standards are a tool to enable comparison of products by providing an independent measurement scale.

Application
2b) Durability

To ensure long life, products must be carefully selected and installed correctly. An investigation of the application’s environment is recommended to identify any chemicals or other corrosive elements that may affect material choices.

Application
2c) User requirements

There is often more than one channel, grate and locking option that will meet hydraulic, loading and chemical resistance needs. User requirements are application specific and are determined by either design preference or legal obligations.
