Dumping Waste in Septics

I have read on several different forums and subjects here of RVers dumping their wastewater into their home septic systems. If you do as I do and use RV chemicals to treat your tanks of the waste and odor then you are doing your septic system great harm. While RVs use chemicals to break down solids home septic systems use bacteria to break down your home wastes. Use of chemicals actually kill these bacterias and negate what a home septic system is designed to do.

Because your home septic system naturally will receive more untreated waste than what you would have dumped from your RV this home waste will not break down as it should and can contaminate the ground around your leach field. Solid waste can reach the leach field causing it to clog. This can as well run off into drinking water or nearby streams, etc. Besides the fact the septic system bacteria will be killed the chemicals in RV waste water treatments can also be of great hazard to the environment.

There is an article from the University of Arizona that explains this and provides a chart of chemicals that are harmful to your septic system and environment. Before dumping in your home septic verify that these RV waste treatments do not contain any of these chemicals.

    Why is dumping waste in a home system any different than dumping in a campground septic system?


    It's not ... seems the OP is answering a question that was never asked, posting merely to stir up controversy. :R Some campground sewer facilities are connected to nearby municipal systems, others waste into their own septic system, but the only caution I've ever seen posted at any of them is to not dump waste treated with a formaldehyde product ... I don't and therefore wouldn't be concerned about where this waste ends up.

    Interesting that the OP would refer to some particular study on the subject but then not provide a link. :R

  • Sorry, but I have been doing it for 50 years and no harm has ever come to my system. Believe what you want, but my system works just fine.

    Yep, either that or go to Wal-Mart and dump it in the storm drain. :B
    We haven't seen one of those posts for awhile.
  • The chems that use formaldehyde will cause problems but the rest wont.

    Use plenty of water, keep the vent open, keep your air admittance valves for the sink drains working correctly, and don't flush with the fan on. Do this and you shouldn't get any odor in the RV.
