System for a
Future School of 500 Students
-
Include Local Building Practices
in the Design
- Secure Funding, Materials
and Labor
- Build the Septic Tank,
Sedimentation
Basin and Adsorption Field

SEPTIC
TANK DESIGN
Two
compartment tank provides better
suspended solids removal
2.2 Gallons H20/student/day
Detention Time = 48 hrs
Tank Volume = 2,200 gal = 294 ft3
Tank Dimensions = 6’ x 13’ x 4’

ADSORPTION
FIELD
Percolation rate = 4.5 min/in
of fall
Max rate of sewer application
= 2.42 gal/ft2/day
Expected flow = 1,100 gal/day
Area for adsorption = 460 ft2
Trench Length = 170 ft
