My leach field is 25 or more years old and seems to be clogged. The ground is firm and there is no smell so I believe the leach lines themselves (possibly in addition to the ground) are clogged. I can't replace them due to lakefront restrictions so am stuck with treating the septic as a holding tank. The septic tank was replaced in 2003 and tied into the existing, clogged leach field by the previous owner.

Does anyone have experience with a solution that might work for me? I'd also like to hear if anyone knows of a reputable source that can back up or deny the claims of fixes like (1) the Septic Genie or (2) bacteria/enzyme additives. My septic guy tells me there are no options out there to fix my situation. This advice agrees with much of what I see on the internet that says additives are a waste of time but the sites that sell these things obviously disagree. How can I tell what is truth?
