Pumping Frequency

The frequency with which septic tanks require removal of sludge and scum to prevent excessive build-up and to ensure the proper functioning of the septic tank in pretreating wastewater. The septic industry has developed guidelines for pumping frequency based on the size of the septic tank, household occupancy and certain household practices (e.g., use of a garbage disposal). Septic tanks should be routinely inspected, (e.g.every 1 - 2 years) to verify solids accumulation and monitor tank conditions. The use of commercially available septic tank additives does not eliminate the need for pumping, and may in fact harm the septic system by dissolving or resuspending solids and sending them on to increase the biological load or foul the drainfield. <
