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.
