Here's another septic practice problem.
1. If the pump tank is 49 inches by 60 inches by 70 inches deep, calculate the gallons per inch.
2. The OFF float is at 62 inches and the ON float activation is at 57 inches. What is the dose volume?
3. If the supply line is 80 feet of 2-inch SCH 40 PVC, what is the drainback volume in gallons?
4. If the cycle counter reads 46,490 today and read 45,850 the last visit 120 days ago, what is the number of cycles recorded?
5. What is the total flow and average flow for the 120 days?
6. If the design flow was 300 gpd for the system, what does this tell you?
If you missed it, here's a brush-up on Simple Septic Math to review first.
This is the fourth in a series. The others can be seen at the links below.
