How do I check the sludge level in my septic tank?
- Slowly lower the tube into the septic tank until it touches the bottom of the tank.
- As the device is slowly pulled out of the water, the check valve closes capturing a liquid/solid profile of the septic tank water. The thickness of the sludge layer can be measured.
Furthermore, how much sludge is normal in a septic tank?
"Generally at a two year interval for septic tank pumping service the average septic tank in these size ranges will have a 400 mm scum layer with about a 200 mm sludge layer. With an average depth of 1600 mm, the solids content is about 600 mm thereby reducing the settling time by nearly 40%.
Secondly, what should the inside of my septic tank look like? My Septic Tank is Full! A septic tank should always be “filled” to its normal liquid level, or the bottom of the outlet pipe which carries effluent to the absorption area. This normal liquid level is usually between 8” to 12” from the top of the tank on average (see picture at right).

What happens to the sludge in a septic tank?
All drains in the home converge to a single pipe that leads to the septic tank buried outside. When it hits the septic tank, however, it begins to separate. The heaviest particulate matter in the waste, called sludge, sinks to the bottom. At the top of the tank, fats, oils and proteins form the floating scum layer.
