Number Of Bedrooms 3

Slope: 0 0

Soil Loading Rate: 0.4

DAILY DESIGN FLOW:

360 Gallons Per Day

DESIGN OF THE INFILTRATION AREA:

1. Size the Infiltration Area

a. Infiltration Rate of Filter Media : 1.0 Gal/Ft2/Day

b. Infilitrative Surface Area (Bed) = Daily Design Flow (Gal/Day)

1.0 Gal/Ft2/Day (Maximum)

1.0 Gal/Ft2/Day (Maximum)

= 360 Ft2

2. Bed Configuration

a. Bed Width (A) = 7.5 ft. (Dependent on Soil Depth. See Table 2)

b. Bed Length (B) =

= 360 FT2

7.5

= 48

DESIGN THE ENTIRE MOUND:

1. Filter Media Height

a. Filter Media Depth (D + E)

1) Depth Below Upslope Edge of Bed (D) = 2 ft or 1 ft if Mound is only for dispersal following Treatment Level B.

1.5 Feet

2) Depth at Downslope Edge of Bed (E)

a. E = D + {% Slope as Decimal x Width of Bed (A)}

1.5 + 0 = 1.5 Feet

b. Bed Depth (F) = 9 Inches (minimum for 1" lateral) in gravel

` F = 0.75 Ft

c. Cap and Topsoil

1) Depth at Bed Center (H) = 18 inches 1.5 Ft

2) Depth at Bed Edges (G) = 12 inches 1.0 Ft

2. Filter Media Length

a. End Slope Width (K) = Total Filter Media Depth at Bed Center X Horizontal Gradiant of Side Slope

K= (D + E) + F+H x

2 (3 if 3:1)

K= 3 + 2.3 x 3

K= 3.75 x 3 K= 11.25

Selected Horizontal Gradiant of Slope

Decimal Slope:

bedrooms x 120 GPD

Required Bottom Infiltrative Surface Area

Bed Width (A)

Mound Worksheet

b. Filter Media Length (L) = Bed Length + [2 x End Slope Width]

L= B+2K

L= 48 +

L= 70.5 Ft

3. Filter Media Width

Side of Slope (3 if 3:1) X Slope Correction Factor (See Table)

Slope Correction Factor = 1

J= (D + F+ G) X Horizontal Gradient x Slope Correction Factor

J= 3.3 X 3 X 1

J= 9.75

Horizontal Gradient of Slope (3 if 3:1) X Slope Correction Factor (See Table

Slope Correction Factor = 1

I= (E + F+ G) X Horizontal Gradient x Slope Correction Factor

I= 3.3 X 3 X 1

I= 9.75

W= J + A + I

W= 27.00 Ft

4. Check the Basal Area

a. Basal Area Required = Daily Design Flow

Infiltration Area

= 360 gal / day

0.4 gal / ft2 / day

= 900 Feet Squared

b. Basal Area Available = B X (A+I)

= B X (A + I)

= 48 X 17.25

= 828 Sq Feet

= L X W

= 1903.5 Sq Feet

Sufficient Basal Area? X Yes No

1) Sloping Site = Bed Length X (Bed Width + Downslope Width)

2) Level Site = Filter Media Length X Fill Width

22.5

a. Upslope Width (J) = Filter Media Depth at Upslope Edge of Bed (D+F+G) X Gradient

b. Downslope Width (I) = Filter Media Depth at Downslope Edge of Bed (E+F+G) X

c. Filter Media Width (W) = Upslope Width + Bed Width + Downslope Width
