Septic Tanks in Washington, DC
At this stage 60%–80% of total suspended solids (TSS) are removed from the wastewater and almost 80% of the FOG is removed. Of the solids removed from the wastewater, some dissipate and others are stored in the tank. Up to 50% of the solids retained in the tank decompose; the rest accumulate as sludge and scum and must be removed periodically.

Septic Tank FAQs
This is a great question and the answer is not the same for everyone. There are charts that take into account the capacity of the tank, the number of fixtures in the home, and the number of people living in the household. These charts are pretty good and can result in excellent guidelines to go by. Others say that having it pumped once every three years is the best rule of thumb.
The best answer that can be used for every tank is that the tank should be pumped when the top layer of scum/grease and the bottom layer of sludge/solids exceed 33% of the total liquid volume of the tank. The wastewater in every septic tank is separated into three (3) distinct layers. All heavy solids will fall to the bottom. This layer is referred to as sludge. All lighter material such as grease will float to the top. This is referred to as the scum layer. The rest of the wastewater will remain in the middle. This layer is referred to as the clear zone. When the layer of scum and sludge added together surpass 33% of the total liquid depth, it’s time to have the tank pumped. This can only be determined when a competent contractor uses a sludge judge, dipstick, or similar tool to take these measurements.
