Septic Systems
Failing septic systems release untreated waste into our groundwater and on the ground. The untreated waste contains viruses and pathogens that are harmful to our health and water quality. Indicators for a failing septic system include:
  • bad odors
  • wet spots
  • lush green grass over the system
  • plumbing back-ups and gurgling noises from the plumbing or tank

If your septic system fails, you must connect to the public sanitary sewer system if it is available. Most properties in Lake Forest Park have sewer availability. If you are unsure, please visit the City's Sewer page for more information.
