City of Saline issued the following announcement on Jan 20.
Just a reminder, there is no delay in trash collection this week.
This is also the last week for tree collection. If you are putting a tree on the curb to be picked up make sure all items (ornaments, stands, lights, etc) have been removed and if the tree is over 6 feet it must be cut in half.
Any trees set out after this week will not be collected.
