We don't want to *see* that there is something buried in the yard.
Otherwise, we might as well save ourselves the excavation work and
just put it *atop* the ground -- as an ugly eyesore! I can hide
the access port (think of it as a manhole cover) relatively easily
(a planting, some sort of lawn furnishing, etc.). But, hiding
something with an ~80 sq ft "footprint" is a bit more challenging!
A 5 bedroom house would require a 2000 gallon septic tank.

With 5 *occupied* bedrooms (a room in and of itself doesn't require
any sewage treatment).

Tell that to the inspector. When applying for your building permit and
septic permit, if the house has 5 bedrooms and is going to be occupied
by a bachelor hermit, it still needs the 1900 or 2000 gallon septic
tank, or you don't get your permit / occupancy permit.

formula for tank volume in US gallons : Length x width in inches / 231
= gallons per inch of septic tank depth. Multiply this number by
septic tank depth in inches to get gallons

Easier to remember 8G/cu ft for a 10% estimate (8 is an easy multiplier
to deal with; double it 3 times) and a factor of 7.5 for a 1% estimate.
Much easier than dealing with "231" and *division*!

(e.g., 16 pi is ~50 to better than 1%)
