If you need to install trench drain systems or if you are taking up a project for the trench drain installation, there are some important decisions you need to make. Not all trench drains are the same. So when you choose a drainage system, it’s essential to select the right trench drain system for residents, streets, etc. Confused about how to choose the proper drainage system? It is a little confusing, but when you understand the basics, drain system selection becomes easy. Here are a few essential things to consider when you are choosing trench drainage systems

Flow Rate

As we know that a drainage system’s job is to drain all the liquid as quickly as possible, you will need to understand the flow rate. The flow rate is how much a drain can remove liquid and how fast. For example, according to some companies, a half-inch slot opening equals 11 gallons per minute per foot of slot, for 1 inch, it’s 18 gallons, and so on. Following the flow rate formula, the trench drain designers customize the depth of the trough for an increase in flow rate.

Loading Limit

Now that you got the idea of flow rate, it’s time to understand the load capacity. First of all, ask yourself how much weight the drainage system needs to handle? In the low-traffic area, the requirements are less. People find that they need their drains to be able to withstand the pressure of heavy equipment and high traffic. If you are thinking of choosing traditional drain systems, you need to consider the material of your grate to make sure it meets the load capacity. Keep in mind that steel grates aren’t invincible and will eventually degrade with time and heavy loads.

Thermal Resistance

When choosing drainage, you need to consider the temperature of the liquids the drainage would deal with. Point out where you are going to use the trench drain system. Will it be installed in industrial plants, residential buildings, breweries, etc. You have to consider the thermal resistance for traditional drains and make sure the drain can withstand the heat.


Alongside the installation, maintenance is the utmost important aspect as well. So don’t forget about cleaning it. You need to ask yourself how to clean it. Which of the drainage components need to be checked and replaced for a prolonged smooth performance? Which tools do you need to clean the system? Some drains eliminate grates, and thus you don’t need to worry much about replacement costs at all.

Chemical Resistance

The trench drain system mostly handles water for residential structures, and that’s okay, but with industries, it needs to be chemical resistant. Cleaning and replacing drains thoroughly is required in order to keep the drain from corroding. Hence a drainage system with corrosion resistance is necessary.


There you go! The things mentioned here are the most important aspects you need to know when choosing or installing the drainage system. Think about these aspects clearly and then decide your next move.
