Landscaping Over Septic Drain Fields | Home & Garden

Plants that have aggressive, woody, water-loving, deep roots can potentially clog or disrupt the pipes in the system, causing serious damage that can be very expensive, very messy and threaten the environment. The key is to select plants that will satisfy landscaping needs while posing as minimal a threat to the drain field as possible.

This 'soil absorption area' is also called a leach field or a septic drain field. Septic drain fields most often consist of a layer of perforated piping that is set in gravel tranches and buried around 12 to 18 inches below the ground. It is here that, after a few initial stages, the final treatment and distribution occurs.

Gold Carbon In Leach Plant Updated January

This plant processes 4 million tons of ore per year with an average gold content of 0.043 ounces of gold per ton of ore. Approximately 85% of the gold is recovered in the plant. From the ball and/or autogenous mill, slurry is pumped to the CIL leach tanks where lime adjusts the pH, if necessary, and it is agitated for the desired period of time.
