Maintaining Duluth Waterways
Stream clean-up and maintenance requires a continuous effort by the
City of Duluth and Youth Employment Services (YES), combined.
YES assists the City Utilities Operations Department with the
Annual Stream Cleaning of Duluth
Streams. The department of Utility Operations steps in to address
specific maintenance problems and to remove the large debris
such as houshold appliances sometimes dumped in the streams.
Sediment traps
In an on-going effort to reduce the amount of sediment and
garbage entering the St. Louis River and Lake Superior, the
city maintains eight sediment traps in Downtown Duluth. Traps
are located near the mouths of Buckingham, Clarkhouse, Coffee
and Greys Creeks and in four other urban locations with large
volumes of stormwater runoff. The traps are designed with
wood or metal baffles to remove sediment and floating debris
from the water flowing through them. Sediment traps are cleaned
1 to 2 times a year, depending on the amount of sand and
debris in the traps, by the Duluth Utility Operations Department.
Stormwater catch basins
Stormwater catch basins are inlets to storm sewers that can
collect some of the sediment and debris washed off the streets.
Catch basins should be cleaned out regularly to function
properly.
There are 250 miles of stormwater sewers with about 9,500 catch
basins located in Duluth City limits. The system is cleaned
by the City of Duluth on a ongoing basis depending on how
much debris is in the system. The entire storm system is cleaned
every 8 to 10 years with some areas receiving additional attention.
To remove debris from the catch basins, they are vacuumed
out with vactor trucks. City employees find everything that
you can think of in the basins: car keys, mufflers, pop bottles,
pipes, sticks and lumber, kids toys, clothing and sleds.
Without the catch basins, and this continuous maintenance,
this debris would wash into the streams impacting both the
health and beauty of the Duluth waterways.
