Aerobic treatment units (ATU), sometimes known as activated sludge tanks, are a common method of biological treatment used in nearly all municipal sewage treatment facilities. This is a means of allowing water to slowly dissipate through the soil. There are two methods: a pit filled with stone or rubble into which the water is discharged, or a system of interlinked trenches containing a perforated pipe surrounded by shingle. The choice and design will be determined by the quantity of space available and by porosity or percolation tests. These tests can establish how quickly water may dissipate and thereby just how big the pit, or perhaps how long the trench needs to be.The unit of measure applied to describe the size of a waste normal water discharge.
