Septic Care and Maintenance Tips

Good care and maintenance prolongs the useable life of your septic system.  Just by following a few simple do’s and don’ts could possibly save money in the long run.  By keeping any objects other than human waste and toilet paper out of your septic, you are off to a good start. 

A septic system and Effluent Disposal Area are not designed to dispose of items such as paper towels, tissues, dental floss, tampons, condoms, cigarette butts, and many other household items.  Anti-bacterial chemicals are also a good idea to keep out of your system.  By pumping on a regular schedule and keeping these items out of your system, your septic should last a long time.
