What is the Catch Basin?
- Plumbing Services

Have you ever seen a manhole cover on your property? Or heard people refer to a Chicagoland catch basin? Many homes in and around the Chicagoland area and certain suburbs such as Niles, Evanston, and Park Ridge still have or had at some point a residential catch basin. Over the years, some have been eliminated or had the piping rerouted, but many are still active and in use today. Many homeowners are not even aware that they have a catch basin or what its purpose is.
What’s a catch basin?
A catch basin is an underground structure usually made of cinderblocks or brick with a metal sewer cover on top. Often the cover is in the backyard, at the side of the house, or even under a porch.
At one time it was common practice that the water from kitchen sinks, laundry drains, and floor drains which would be directed and terminate at the catch basin. The idea of this is to keep certain materials from entering the city sewer system. The heavier debris would settle out at the bottom, while lighter debris such as cooking grease and soap scum would float to the top thus protecting the main sewer line from clogging. Roof gutters and downspouts often have connections to catch basins as well, allowing debris and leaves from the roof to separate out prior to entering the sewer system.
Over time this debris can accumulate in the catch basin, preventing proper flow. This can lead to problems with sewer line blockages or the basement backing up through the floor drains. It is important to clean and maintain your catch basin. Depending on usage it may be necessary to have it cleaned every couple of years.
Catch basin cleaning is often something people overlook, resulting in basement flooding. However, it is easy to overlook if you are unaware that you even have one, or what a vital part of your home’s drainage system it is.
