| Looking for a good way to dispose of wash water containing dough and yeast. At a bakery that produces about 800 loaves of bread a day, the wash sink drained to a small septic tank then to a french drain. The french drain plugged up and smelled awful. Now the sink drains out to the surface, into a banana tree grove. Appears to be a harmless discharge, but now it attracts rats. Would like to keep it from the rats, maybe best underground, but the dough and yeast seem to plug things too quickly. Any suggestions would be appreciated – the bakery is run by a charity and is outside of the U.S., and is looking for a cheap and easy way to handle this wastewater. Thanks |

| | The french drain plugging up is obviously indicative of poor solids separation in the septic tank (I assume you were occasionally pumping it out, yes?). Since you used the term "small" I'm led to believe it may simply due to an undersized unit (which would also account for the odor.) |

Would it be possible to install some type of screen material between the sink drain and the French drain? If you can remove the solids the waste water would percolate well from the drain. The solids should be disposed of regularly, possibly by the local landfill or dump, or by burying on the site, if that is reasonable.
Another option might be to scatter dry lime (quick lime or hydrated lime) in the area where the waste is now flowing. You would want to mix the lime into the soil. This might keep the rats from visiting. But, I expect that the rats are mostly interested in the dough solids, and not so much the waste water.

| | Scrape the dough and yeast out of the bowls before washing. You can probably feed the dried scrapings to chickens or hogs. It is better to keep the stuff out of the system if you can. Mark |
