  • Always use the designated amount of cleaning detergents for toilets and drains
  • Replace old fixtures with “low flow” ones to help conserve water
  • Replace or repair any broken fixtures that are dripping or leaking in any way
  • Keep the run of the outdoor roof drains away from the septic tank areas
  • Keep the septic tank cover free from blocking objects, this makes for easier septic inspections
  • Frequently check to make sure there are no blocked air vents
  • Always hire a licensed professional to handle any inspections or repairs
  • Regularly have tank services done
  • Frequently run water in rarely used drains (any sinks or showers, etc.) to avoid toxic chemicals from building up in the drains and causing terrible odors on your property


  • Never overload a water system (consecutive loads of laundry or running multiple appliances at once)
  • Don’t dump any solids into the sink
  • Don’t pour any oils or fats down the drain
  • Don’t use your sink or toilet as a disposal for your garbage
  • Don’t put yeast down the sink or any other commercial products
  • Don’t plant any trees around the head of the septic tank as the branches can ruin the pipes
  • Never cover the tank bed with hard substances like concrete or asphalt
  • Do not flush anything but human waste or toilet paper down the toilet (the ideal toilet paper is 1 ply)
  • Other products to not flush: coffee grounds, baby wipes, dental floss, cloth, tissues, medications, sanitary napkins, disposable diapers, etc.
  • Never enter the septic tank or inspect it on your own-there are dangerous (and fatal) chemicals used during the treatment process
