Septic Care

Even the best septic system needs to be maintained.  Please call Hamman to speak to learn more about proper care.


Generally a septic tank should be pumped every 3 to 5 years.

Proper Maintenance

  • Keep vehicles away from the system. DO NOT drive over the tank or leech field.
  • Do not plant trees or shrubs near drain fields as roots will eventually clog the lines.
  • Dispose of household chemicals properly. Do not pour them down the drain.
  • Distribute laundry throughout the week to avoid overloading in one day.
  • Do not use the toilet as a trash can. Flush only toilet paper and waste down.
  • Monitor your tank yearly and have a licensed contractor pump it every 3 to 5 years.
