Operations & Maintenance – Keeping the System Flowing
The Public Works crew is responsible for the maintenance of approximately 225,000 feet of gravity sewer main, 11,000 feet of pressure main, and the operation and maintenance of two lift stations. The sewer system is cleaned in order to remove the troublesome sand, grease and other restrictions that can cause sewer backups. Sewer overflows and backups can cause health hazards, damage homes and the environment.
The City wants to remind our customers that putting fats, oils, grease (FOG) or trash down a sink or toilet can create a situation that is both unhealthy and expensive not only to the City, but to you personally. Putting these materials down a sink or toilet can lead to a clogged sanitary sewer line. Clogs can then lead to wastewater backing up into your home or business, spilling out onto the streets, and even finding its way into storm drains, Lake Washington, and Puget Sound.
While the City maintains the community-wide sewer system, the sewer line within your own home and on your property out to the sewer main is the responsibility of the property owner. If you find that your home's sewer lines have become clogged with FOG, it may require either do-it-yourself maintenance or assistance from a plumber to clear the blockage.
Connecting to Sewer
In 2004 the City began a program to expand sewer availability to all residences within its sewer district. The project was broken into three phases and was completed in 2008 with a total cost of $5.48 million. To accommodate flat areas or uphill sloped areas the City utilized a pressure type system as an alternative to the gravity system. As a result, there are two types of sewer connections in the City; pressure and gravity.

On-Site Wastewater Systems
Residences with sewer availability (sewer main is within 100' of the property line) must connect if their on-site wastewater system fails according to Lake Forest Park Municipal Code (LFPMC) 13.10. Whenever the property is sold, changes ownership or is re-financed, you must pay the side-sewer connection fee. Connection to the public sewer system is not required when a property is sold, changes ownership or re-financed.
Residences that are operating functioning on-site wastewater systems are required to obtain a on-site wastewater system license from the City. View a list of properties that are subject to the on-site wastewater system requirements.
