Septic leech field... built around existing tree

Not sure of the Copper Sulfate (definitely NO on flushing it) but adding a Nylon Stocking full hung into the diverter box could be OK so anytime a rush of water is sent out it gets a dab of Copper Sulfate.

Mark, I'm not sure why you say "no flushing" of copper sulfate. I suppose that response has to do with introducing it into the septic tank. As far as I know, the amounts of copper sulfate in a single treatment would not be enough of a biocide to cause septic tank problems. Most all of the commercially available root control agents are copper sulfate. Roebic is one example that says it is safe for septic tanks. The method of introduction is to flush it down the toilet. Most instructions I read say to introduce no more than 2-4 oz at a time and flush. The copper sulfate crystals will expand, but if you flush small amounts with plenty of water, the crystals will all clear through the commode. If you have severe problems with water backup between the house and septic, then using copper sulfate is not an option. For this, mechanical removal is needed before any chemical solution is added.

Anyhow, I'm just curious why you strongly suggested to not flush the copper sulfate.:confused3:

Jim:

Main reason is the Copper Sulphate crystals are heavier than the normal waste & will drop into the bottom of the digester part of your septic tank. It will also KILL any growing plants & bacteria inside the digester tank inhibiting it's ability to handle the waste. It could then cause the septic to contaminate the leach field if the digester slows. The hanging of a nylon stocking full of it on the exit pipe field box will mean the copper will only go into the field lines and not into the tank.

We treat lakes with it often around here to try & control cattails, mil-foil or watercress. When you spread it out even dragging it around in a boat the blue color will sink pretty quick to the bottom.
