On Site Septic Systems (Thurston County Customers)

If you have a septic system, you are NOT connected to the City sewer system. Many Thurston County residents have an on-site septic system in their backyard that treats wastewater from toilets, dishwashers, laundry, showers, tubs and more. In order for your septic system to do its job, it needs regular inspection and maintenance to protect your investment and our community's drinking and surface waters. Homeowners are responsible for the repair and maintenance of on-site septic systems.
   
All of Lacey's drinking water comes from groundwater which means a failing or improperly functioning septic system puts our drinking water at risk. Therefore, it is important to have your septic system inspected every 1-3 years and pumped every 3-5 years.


 
To prolong the life of your septic system

  • Conserve water in your home.
  • Do not flush solids like cigarettes, tampons, baby wipes, grease, etc. down the drain or toilet.
  • Avoid the use of your garbage disposal or use less frequently.
  • Do not use septic tank additives. They do not replace the need to pump your tank.
  • Never drive or park a vehicle on your septic tank or drain field.
