BUOYANCY CALCULATIONS
1500 GALLON SEPTIC TANK-Monolithic-HI O (Shorey Precast Concrete Products)
High Groundwater Elev. -Bottom of Tank = Submerged Depth
E1. 3.8 - EI. 2.4 = 1.4'
Submerged Volume x Weight of Water = Buoyancy
10.2'x 6.1'x 1.4' x 62.431bs/cf = 5,4381bs T
Tank Weight(empty)per Shorey Co. Specs. = 11,833 lbs �
Effective High Groundwater Tank Wt. = 11,833 lbs–5,4381bs=63951bs .�
