Pumping FrequencyWorksheet

Cleaning Frequency Guidelines
How often a septic tank needs to be cleaned depends on the tank's design and the way it is used. In this worksheet, factors that increase the cleaning frequency are called effects and the factors that reduce the cleaning frequency are called credits. The frequency guidelines calculated with this worksheet should be used along with the conditions observed when the tank is cleaned to decide when the tank will next need cleaning.
