 Catch basins are storm sewer inlets that
filter out debris such as leaves and litter.
They are typically located next to street curbs
or within the rear yards of residential areas.
It is important to maintain catch basins to
prevent storm sewer blockages and minimize the
amount of pollutants entering storm sewers,
which discharge into detention basins or
directly into streams.
Clogged catch basins can also cause water to
pond along streets and in yards and parking
lots. This flooding can be a nuisance to
motorists and businesses.
Are You Responsible for Catch Basin Care?
Your business is responsible for maintaining
any catch basin that is located on your
property.
How Are Catch Basins Maintained?
- Remove Debris from Grates
The grates of catch basins can become clogged
with litter or leaves, especially in the
spring and fall. Regularly inspect the grate
and remove debris.
- Remove Debris from Storage Area
Catch basins should be cleaned out before the
storage area is half full. Once this level is
reached, debris begins to wash into sewer
pipes. Cleaning should be done in the spring
after the first large snow melt, in the fall
after trees have shed their leaves, and
additionally if needed.
To find out how much material has accumulated
in the storage area of your catch basin, insert
a long pipe or broom stick into the storm drain
grate. Notice where the pipe or stick hits the
debris and continue to the bottom to estimate
the depth of accumulation.
If the catch basin is shallow enough, you may
be able to clean it out yourself with a shovel
and bucket. Be careful not to drop the grate
down the opening when you remove it; it can be
extremely hard to retrieve. If you can't perform
your own maintenance, professional services are
available to do it for you.
