6. The septic tank of claim 1, wherein the tank top section and tank bottom section are securely connected to form the septic tank.

7. The septic tank of claim 1, wherein the internal support is configured to limit distortion of the tank to a range of about 0.7% to about 5% when a vacuum of about 3 inches to about 7 inches of Hg is applied to the tank interior cavity.

8. The septic tank of claim 1, wherein the internal support is configured to limit distortion of the tank to about 2% when a vacuum of about 5.8 inches of Hg is applied to the tank interior cavity.

9. The septic tank of claim 1, wherein the septic tank includes a septic tank length and when the at least one internal support is associated with the at least one end wall pocket and the at least one side wall pocket, the at least one internal support is arranged diagonal relative to the septic tank length.

10. The septic tank of claim 1, wherein,
