Here's another septic practice problem. This is the third in a series. The others can be seen at the links below. 

  1. If a pump tank has the following dimensions, 42 inches by 60 inches by 58 inches deep, what are the gallons per inch?
  2. If an off float is set 52 inches from a surface reference point and the on float is activated at a depth of 46 inches, what is the dose volume?
  3. From the reference point, where should the high-water alarm float be set?
  4. If there is 6 inches of sludge in the tank, what does this tell us?

If you missed it, here's a brush-up on Simple Septic Math to review first.
