SEPTIC SYSTEM DESIGN
DESIGN CRITERIA;
Existing 3 bedroom type 1 single family home with a garbage disposal currently
used as a guest house without a garbage disposal.
WATER USAGE;
450 gallons per day m�imum•
PERCOLATION RATE;
13 minutes per inch.
SEPTTC TANK; _
_
Pump collapse and fill existing. Install a 1,500 gallon double compartment sept�c
tank. Please see detail.
Notes: Tanks require pumping once every three years.
pUMP CHAMBER;
Install a 1,000 gallon precast tank. Set as specified.
Notes: An event counter required.
DRAINFIELD;
Treatment Mound,Pressure distribution required. Located on 5% slope. Total
mound area is 45 feet wide by 62 feet long. Rock bed measures 10 feet by 3 8
feet. Downslope dike width is 23 feet,upslope dike width is 12 feet and the end
dikes are 12 feet. 220 Tons of sand required. Please see detail. .
GENER.AL CONSTRUCTION PRACTICES;
Divert all surface water away from the dra.infield azea. Do not disturb the
drainfield area during construction. Fence off the drainfield area before permit
� application. If there are any questions regarding this design please conta.ct Tom
Klanchnik at(952) 758-6278.
