The smaller the percolation soil particles, (soils with clay or silt as part of their structure) the smaller the air spaces in the soil and the faster they block with these suspended solids.Septic tank bristle filters trap these particles and prevent them from clogging the percolation area.We highly recommend fitting one of these to save your percolation area.
