Placeholder Sand Traps and Catch Basins — What's the Difference?


Sand Traps and Catch Basins — What's the Difference?

When it comes to drainage systems for landscaping, sand traps and catch basins are among the most popular options. However, if you’re new to the world of drainage systems, you may be unaware of the differences between these two choices. 

Keep reading to learn more about sand traps and catch basins and the difference between these choices. With this information, you’ll be able to make an informed decision about which is the best option for you. 

What Are Sand Traps?


Sand traps separate sediment from wastewater

Sand traps are one of the most effective drainage solutions in the landscaping world. In fact, even if you don’t know what they are, there’s a good chance you’ve heard the term sand trap before. Sand traps effectively capture and separate sediment from wastewater and/or stormwater runoff. They are designed to prevent the deposition of coarse particles in downstream components such as pipes, channels, and treatment facilities. 

Sand traps come in a variety of shapes and sizes, such as rectangular or circular, and are strategically placed where the flow velocity is reduced, allowing sediments to settle. The design includes features to guide water flow into the trap and facilitate the exit of filtered water while retaining the sediment. 

It’s important to note that regular maintenance is essential to remove accumulated sediment through physical removal or flushing procedures. By preventing the clogging of downstream components, sand traps contribute to the overall efficiency and longevity of drainage systems. Integrating sand traps into your drainage system reflects a proactive approach to managing sediment and maintaining the functionality of the drainage infrastructure. 

Types of Sand Traps

Sand traps come in two types. Gravity sand traps, as their name suggests, use the effects of gravity to help remove sand and other sediment from water. Gravity sand traps do not have any moving parts contributing to their longevity.

Centrifugal sand traps, on the other hand, use centrifugal force to separate sand and other sediment from water. Once water enters a centrifugal sand trap, sand and any additional particles are moved to the outer walls and are collected in the lower area of the device while the water exits through the top. 

What Is a Catch Basin?


Catch basins lead the wastewater away from certain areas

The term catch basin may not be as widely known, but these basins are another excellent drainage option. Catch basins, which are sometimes referred to as storm drain inlets, are made for collecting and managing stormwater runoff. They are typically designed with a grate and a pipe connection that work together to drain water away from a specific area. The grating acts as a way to ensure that things like sticks, leaves, and other debris are separated from the water, which ultimately helps prevent the plumbing system from becoming clogged. 

When the water in the catch basin reaches a certain level, the excess water travels from the pipe to a new location.

Types of Catch Basins

Like sand traps, a catch basin drain also comes in two general types: open and closed systems. Open systems are designed with bars or grates on top to let water and debris enter the basin. On the other hand, closed systems use solid covers to stop debris from getting into the system.

How Do Sand Traps and Catch Basins Differ?

Now that you have more information on what sand traps and catch basins are, you’re probably wondering what the difference is. After all, they both essentially do the same thing. However, while they essentially have the same function, they are mostly distinguishable by their designs and their common use cases. Sand traps are designed to remove sediment by slowing down the flow of the water and allowing particles to settle. In addition to using a grate, catch basins also usually connect to plumbing systems and move water to larger stormwater management systems. 

On top of that, sand traps and catch basins tend to work better on different types of sediment and debris. For example, sand traps are best for catching and separating things like sand and gravel. Catch basin drainage captures a wider variety of things including leaves and trash. 

One of the biggest differences between sand traps and catch basins, however, comes with where they are primarily used. Sand traps are strategically placed in areas where water flow is reduced, while catch basins are placed in areas where stormwater runoff is common. 

Which Option is Best for Your Landscaping Design?

Deciding whether to use sand traps or catch basins will depend on various things, with one of the main factors being the layout of the area. For example, catch basins are most commonly used in places like streets (storm drain catch basins), sidewalks, and parking lots. Sand traps are often used in golf courses and man made bodies of water. Temporary sand traps can also be used at places like construction sites. 

You may want to consult with an experienced professional to better understand which solution will make the most sense for your landscape.
