Tips for Maintaining Your Landscape Drainage

Outdoor drainage is important for year-round management of excess rainfall. Unfortunately when they’re not maintained properly, you can get a magnitude of issues which can really cause a headache. The following are some useful tips to maintain your landscape drainage.

French Drains

We recommend checking the grates of your box drains and the gravel of your French drains (with gravel to the surface) regularly and remove any debris.  Check drains more often in the fall or other times when debris can quickly cover your drain.  Debris over a drain can make your drain ineffective and cause major water problems.

Outdoor Box Drains & Your Yard

Box drains are designed to allow debris to settle into the bottom so it does not clog the drain pipes.  This is why you may see a small amount of water remain in a bottom of a drain after a rain event.  This debris should be cleaned out 1 – 2 times per season depending on how much debris you have moving into the drain.  Open the grate of each box drain (this usually involving taking out a few screws) and clean out any debris that may be in there. A wet/dry shop vacuum can help because it can reach further than your hands to remove more debris.  Next, flush the drain with a garden hose.  Put the hose in the drain box and a few feet into the drainpipe if you can.  Allow the water to run for about two minutes per drain.


If your drain system has a clean out remove the top of the clean out and flush the pipe with hose water. If you are uncertain about any of this please contact your Eichenlaub consultant or project manager.
