General Septic Tank Maintenanceseptic tank

The septic system is an efficient, inexpensive , and convenient method for treating and disposing of household wastewater.  Septic systems will adequately absorb and purify wastewater if they are properly maintained. A few precautions can save you anguish and money. Reducing water use, avoiding grease, pumping tank periodically, and properly landscaping the yard to keep surface water away from the tank and drain-field are inexpensive precautions that can help assure your system a long life.

 

  • Do not put too much water into the septic system; typical water use it about 50 gallons per day for each person in the family.
  • Do not add materials (chemicals, sanitary napkins, applicators, and so on) other than domestic wastewater.
  • Restrict the use of your garbage disposal.
  • Do not pour grease or cooking oils down the sink drain.
  • Make a diagram showing the location of your tank and drain-field and repair area.
  • Install a watertight concrete riser over the septic tank to simplify access.
  • Periodically have the solids pumped out of the septic tank.
  • Maintain adequate vegetative cover over the drain-field.
  • Keep surface waters away from the tank and drain-field.
  • Keep automobiles and heavy equipment off the system.
