PSD-SEPTIC TANK CALC’S
Liquid Capacity:
Each Student : 20 Gallons (76 liter) Waste per day Assumed 50 students and office members x 20 Gals/day= 1000 gals (3785 liter)
1000x 1.5 = 1500 gals ( 5678 Liter / 5.7 cubic meter)
Assume the inside septic tank liquid: 4’wide x 5’ depth 10’ long= 200 cubic foot
200x 7.48/gallon/cubic foot= 1500 gallon (5.7 cubic meter) OK
Add 12” on top of liquid.
Septic Tank inside dimensions : 4’x6’x10’ (1.22x1.83x3 M)
Exterior dimensions: 5’x7’x11’ ( 1.52x2.13x3.35 M)
24” or 2’ ( 61 CM) Soil on top.
The depth is 9’ (2.74 M)
