How Heavy is a Storm Drain Cover?

Have you ever wondered how heavy a storm drain cover is? Storm drain covers are essential to keeping our streets safe during rain and snow storms.

But just how heavy are they? Read on to find out the answer to that question and more!

How Heavy is a Storm Drain Cover?

The average weight of a storm drain cover is 249-255 lbs. That’s right, your average storm drain cover weighs as much as a large adult human!

This makes sense when you think about it – after all, these covers need to be able to withstand the elements and keep debris and dirt out of the drains. The added weight also ensures that the covers stay firmly in place.

Speaking of materials, most storm drain covers are made from reinforced concrete or steel. These materials are both very durable and can stand up against extreme weather conditions such as hail, wind, snow, and more.

In addition, some covers may also be coated with special paint or sealant which helps protect them from rusting or becoming damaged over time due to water exposure.

Lastly, many cities require certain types of storm drains to be covered with metal grates rather than solid covers. This allows for better water drainage while still preventing debris from entering the drains.

However, these grates still need to remain firmly in place; therefore they are often weighted down with stones or other heavy objects placed around their edges.


As you can see, storm drain covers serve an important purpose in keeping our streets safe during inclement weather conditions and helping keep debris out of our sewer systems.

Knowing the average weight of these covers gives us an idea of just how sturdy they have to be in order for them to do their jobs effectively – not an easy feat considering that most weigh as much as an adult human being!
