Settling ponds or tanks, a scaled-up version of a Mason jar, is a method used to remove suspended solids from different types of wastewater. The wastewater is pumped into a large holding tank where it is held. The heavy particles will fall out of suspension and sink to the bottom leaving clear water to exit the pond. But, as the Mason jar test shows the time that wastewater needs to stay in the pond depends on the soil type.
So, settling ponds, whose entire purpose is to give particles time to sink, and muck, a soil type resistant to sinking, are a mismatched pair. They can still work together if the additional time for the muck to settle out is taken into account or as one part of a multi-step treatment process.
