 Read and follow the Dos and Don’ts listed below:
DO
  • Conserve water to reduce the amount of wastewater that must be treated and disposed.
  • Repair leaking faucets and toilets promptly.
  • Only discharge biodegradable wastes into system.
  • Divert down spouts and other surface water away from your soil treatment area
  • Keep your septic tank cover accessible for tank inspections and pumping. • If lid is at grade, make sure lid is locked or secured and if possible, a secondary safety device is installed. •
  • Have your effluent screen inspected and cleaned once a year. Make sure that the screen is ALWAYS replaced after cleaning. •
  • Have your septic tank pumped regularly and inspected for leaks and cracks. •
  • Call a professional when you have problems. •
  • Compost your garbage or put it in the trash instead of putting it down the sink. •
  • Make sure any water conditioning or softening equipment is approved for use with your system and that it is properly set for your water conditioning/softening needs and operating correctly.
​DON’T 
  • Flush wipes, sanitary napkins, tampons, disposable diapers, condoms, cat litter and such products into your system. •
  • Dump solvents, oils, paints, thinners, disinfectants, pesticides or poisons down the drain; these can disrupt the treatment process and contaminate groundwater. •
  • Dig in your soil treatment area or build anything over it. •
  • Plant anything over your soil treatment area except grass. •
  • Drive over your soil treatment area or compact the soil in any way. •
  • Use a garbage disposal. (They are not recommended, but if one is present, make sure the system is designed with appropriate additional capacity.) SAFETY FIRST! •


NEVER physically enter a septic tank or other parts of the treatment system.

Call your service provider! • Keep access areas locked at all times to prevent unauthorized entry; if possible add a secondary safety device to prevent accidents.
