How do you calculate the volume of a septic tank?
The formula is length (feet) x width (feet) x 1 foot x 7.5 gallons, which is the volume for 1-foot depth. To find the volume for 1 inch I divide the volume by 12 to give me gallons per inch. For our example this is 5.16 feet x 7.5 feet x 1.0 foot x 7.5 gallons per cubic foot = 290.2 gallons.
How is septic tank design calculated?
Space above liquid level is 0.3m depth. So the volume of space above liquid level is 2.76m2 X 0.3 = 0.828m3. Hence, total volume of septic tank for 20 person with a sludge clearance period of one year is = 0.828 + 0.64 + 1.46 + 0.828 = 3.756 m3 .

So the septic tank should have the capacity to retain the household wastewater at least 3 days. Let us take 2000 Liters capacity minimum for a home. Minimum depth of Septic tank should not be less than 1.8m. Sludge settled down per person – 30 liters/year.
What is the minimum septic tank size in Alaska?
For example the Alaska state regulation (18 AAC 72) specifies that the minimum septic tank size shall be 1000 gallons for a home with three or fewer bedrooms.

How much sludge can a septic tank hold?
So the septic tank should have the capacity to retain the household wastewater at least 3 days. Let us take 2000 Liters capacity minimum for a home. Minimum depth of Septic tank should not be less than 1.8m. Sludge settled down per person – 30 liters/year. So here we take sludge removal 2 years once. So 4BxB = 1.2 Sqm where B=0.54m
