Septic Care Tips
  • Take care of your septic tank so it will take care of you!
    Have it inspected or pumped every 3- 5 years depending on how heavily it is used. Do not put products that could kill the bacteria working in your septic tank down the drain! Septic tank additives are NOT necessary or recommended. Be aware of the signs of a failing septic system – slow drains, odors, or soggy ground over the drain field. Water conserving fixtures and conservation in your home help manage the volume of water your system has to treat.
