The septic tank should be pumped at a frequency depending on the wastewater flow. The recommended pumping cycle is three (3) to five (5) years, but pumping should not occur until the settleable solids have reached a depth of 1/3 the septic tank liquid depth. This can be determined by "sticking" the tank.
