If you suspect a sewer obstruction or back up and do not know where the blockage is, contact the City of Forest Lake Utility Department before contacting a drain cleaning company. The city will inspect the sewer main through a manhole to determine if there is a blockage in the sewer main line. If there is no problem in the sewer main, the blockage is in your sewer service pipe between the sewer main and the house. Often times root invasion from mature trees into old sewer services are causes of obstruction.

Call Forest Lake Utility Department @ 651-209-9743

Monday-Friday, after hours, on weekends or holidays

A message must be left at this number in order to allow

City crews to be dispatched to assess the situation.

If it is determined that no blockage or restrictions exist in the City's sanitary sewer system, the property owner is advised to contact a professional plumber or drain cleaning service to have the private sewer service inspected. The City cannot make a recommendation for drain cleaning services. A property owner may wish to obtain several estimates. We do however request that you notify us after a sewer service has been cleaned. Typically, the cleaning process pushes a significant amount of solids into the sewer main and could cause a blockage in the main, which could lead to an even bigger problem.
