  • Reviewing applications and plans and issue permits
  • Inspecting disposal systems for proper installation or repair
  • Requiring anyone constructing, altering, or extending private sewage disposal systems to have a valid permit issued by the health department
  • Providing information about construction, operation, and maintenance to citizens and contractors

Tips for taking care of your septic system:

  • Know where your septic and drain field are located. Keep a sketch with your maintenance records
  • Inspect your septic tank every year

  • conserve water to avoid overloading the system
  • Have your tank pumped every 2 to 3 years by a licensed septic pumper
  • divert other water sources like gutters, footing drains, and sump pumps away from the septic system
  • do not park or drive cars over your drain field
  • don't dig in your septic system
