Septic System �anagement Plan
for Above Grade Sy�tems
The goal of a septic sysiem is to protect human heaIth and the environznent by properly treating
wastewater before returnina zt to the environment. Your szpt:c system is desi�ned to kill hannful
organisms and remove pollutants before the water is recycled back into our lakes, streams and
groundwater.
This management plan wi11 identify the operation and maintenar�ce activities necessary to ensure ion�-
term performance of your septic system. Some of these activities must be performed by you, the
homeowner. Other tasks must be performed by a licensed septic maintainer or service provider.
However,it is YOUR responsibility to make sure aIl tasks�et accomplished in a timeIy manner.
The Uruversity of Minnesota's Septic System Oivner's Guide contains additional tips and
recommendations designed to extend the effective life of your syst�m and save you money ovez rime.
Proper septic system design, installation,operation and maintenance means safe and clean water!

2. DISPERSAL MEDIA SIZING
A. Calculate Required Dispersol Bed Area:Design Flow (1.A):Design Media Loading Rate (1.E)=ft2
If a larger dispersat media 750 GPD= 1.20 GPO/ftZ = 625 ft2

B. Calculate Dispersal Bed Width: Contour Loading Rate (1.G):Design Media Looding Rate (1.E)=Bed Width
12.0 ft = 1.2 gpd/ft2 = 10 ft
C. Calculate Dispersa(Bed Length: Dispersa!Bed Area (2.A):Bed Width (2.6)=Bed Length

B. For slopes>1%, the Absorption Width is measured downhill from the upslope edge of the Bed.
Catculate Downs(ope Absorption Width:Absorption wdth (3.A) - Bed Width (2.6)=ft

D. Get area from manufacturer �ft�
E. Get gallons per inch from manufacturer 25.5 Gallons per inch
2. Calcutate Ga!lons Per Inch:
There are 7.48 galtons per cubic foot. Therefore,multiply the area from 1.A,1.6,or 1.0 by 7.48 to determine the gallorn per foot
the tank holds. Then divide that number by 12 to calcutate the gallons per inch.
(Area X 7.48 gallons/ft3)/(12 in/ft)_
� � X 7_48 gal/ft3 = 12 in/ft = 25.5 Galtons per inch
TANK CAPACITY
3. Enter the Designed Pump 7ank Copacity(minimum provided in the tabte below): 1300 Gallons
4. Calculate Total Tank Volume
A. Deptn from bottom of inlet pipe to tank bottom: 57 in
B. Total T�k Volume =Depth from bottom of inlet pipe (Li�re 4.A)X Ga(lons/Inch (Line 2)
57 in X 25.5 Gallons Per tncfi = 1452.9 Gattoru
5. Calculate Volume to Cover Pump (The inlet of the pump must be at teast 4-inches from the bottom of
the pump tank 8 2 inches of water covering the pump is recommended)
(Pump and block height+2 inches)X Gal(ons Per Inch (1D or 2)
( 12 in + 2 inches) X 25.5 Gailons Per Inch = 357 Gatlons

7. Calculate Mcrximum Pumpout Volume (25%of Design F[ow)
Design Flow: 750 GPD X 0.25 = 187.5 Galtoru
8. Select a pumpout vo[ume that meets both items above (Line 6 Fr 7): 187.5 Galloris
9. Calculate Doses Per Day =Design Flow:Dosing Vo(ume
750 �pd: 187.5 gal = 4.0 Doses
10. Calculate Drainback:
A. Diameter of Supp(y Pipe= �inches
B. Length of SupQly Pipe= 100 feet
C. Volume of Liquid Per Lineal Foot of Pipe = 0.170 Gatlons/ft
D. Drainback =Length of Supply Pipe X Volume of Liquid Per Lineo(Foot of Pipe
100 ft X 0.170 gat/ft = 17.0 Galloas
11. Toto!Dosing Volume s�osing Volume (Line 8)plus Drain6ack (Line 10.D)
187.5 gal+ 17.0 gal= 205 Gattons
12. Minimum Alarm Volume=Depth of alarm(2 or 3 inches)X gallons per inch of tank(Line 1 or 2)
