I have a cylindrical (round) tank that has a diameter of 4 feet and is 5.5 feet deep below the invert of the outlet. (Hint: remember )
- What is the operating volume in gallons?
- What are the gallons per inch?
- If the flow is 600 gallons, is it large enough?
- If sludge plus scum equals 15 inches does it need to be pumped? What if sludge plus scum equals 24 inches?
If you missed it, here's a brush-up on Simple Septic Math to review first.
