Maintenance Tips for Keeping Your Septic System Working Properly

  1. Tanks need to be evaluated every two to three years and pumped if necessary. New homes – pump within 3 – 12 months of occupancy for the first time. (See Worksheet for frequency of pumping)
  2. Never use additives. The cleaners are harmful to your system. They do not replace good management practices. Starters and feeders are not effective.
  3. Maintain grass cover over the drain field. Maintain cover by mowing but do not fertilize, burn or overwater.
  4. Do not drive or park vehicles, bikes, snowmobiles etc. across the drain field creating soil compaction causing the system to not operate properly or even fail.
  5. Do not plant shrubs or trees near drain field. The root system can cause the system operate inefficiently or even malfunction.

  2. Do not use a garbage disposal or dispose vegetables, meat, fat, oil, coffee grounds, and other food products in the septic system.
  3. Reduce the use of drain cleaners by minimizing grease and food wash down the drain. Keep drinking water in the fridge to minimize water usage.
