How Often Should You Change Your Storm Drain Filters?

storm drainStorm drain filters are the easy solution for keeping waste out of the water system. But these filters only work their best for so long before you need to replace them. There are a few telltale signs that it’s time to replace your storm drain filter.

  • Sediment buildup — If there is one-quarter of an inch or more of sediment buildup, your filter insert most likely needs to be replaced.
  • Debris buildup — Buildup of large debris, such as trash, might just mean that the drain filter needs to be cleaned, but keep an eye out for any other signs that it needs to be replaced.
  • Standing water — Four inches or more of standing water around the drain 24 hours or longer after rain is a sure sign that your storm drain filter requires maintenance or replacing.
  • Hazardous material discharge — If any hazardous material that the filter is intended to absorb (such as motor oil) is being discharged by the filter, it’s time for a replacement.
  • Visible scum — It’s time to replace the filter if there is a visible line of scum building up around it. This is usually a sign of recurring standing water.
  • Three years — Regardless of the state of the filter, if three years have passed without it being replaced, it’s time!

We have three different storm drain filter models available, so you will be sure to find one that suits your specific facility needs. Check them out on our website.
