If you pay a sewer charge on your water bill, you are on a sewer system. If not, you should be on a septic system. To confirm, contact the Clarke County Health Department's Environmental Health Section at 706-583-2658 or 706-583-2658.

On average, around every 3-5 years. However, the real timeframe varies and depends on your water use, the size of the tank, the number of people in the house, and types of appliances in use such as garbage disposals or washing machines. The Cooperative Extension booklet "Protecting Your Water and Septic System" has a helpful risk assessment and chart of more specific recommended pumping times.

There are a variety of opinions on this (as well as a variety of additives). It has not been proven that additives assist in the effectiveness of septic system operation. A properly functioning and maintained one does not need additives. If you do decide to use additives, note that you will still need to have your tank inspected and pumped regularly.

Less expensive than waiting for one to fail! Barring any other problems, it should cost a few hundred dollars to have a tank pumped. When pricing an inspection and pumping, beware of low-ball figures that add costs later such as extra hoses once they are on site. Get a few quotes and ask about what additional charges may be incurred.
