A Pressure dosing required.

B One third reduction may be permitted for use of an aerobic tank.

C May be considered for experimental or alternate proposals.

D Unsuitable for subsurface sand filters.

(e) Spray fields. Table B shall be used in calculating the square footage of spray fields based on flows determined in Subsection (a). Table B includes allowances for garbage grinders, automatic washing machines, dishwashers and water softeners.
