SEPTIC SYSTEM DESIGN
DESIGN CRITERIA;
Existing 4 bedroom type 1 single family home, without a garbage disposal. Has
been remodeled to a 3 bedroom type 1 single family home, without a garbage
disposal. Customer requests additional capacity for possible addition of detached
garage with guest bedroom and bathroom. Design as a 4 bedroom type 1 single
family home, with a garbage disposal
WATER USAGE;
600 gallons per day maximum.
PERCOLATION RATE;
3.2 minutes per inch.
SEPTIC TANK;
Pump, Collapes, and fill existing tanks. Install one 1,500 gallon double
compartment septic tank. Please see detail. Note: tank requires pumping once
every three years.
DRAINFIELD; S
Drainfield trenches,)Fflsquare feet required square feet proposed. Each
trench is 36 inches wide with 6 inches of rock below the pipe. ineal feet of
trench proposed. 9 ,00
GENERAL CONSTRUCTION PRACTICES;
Divert all surface water away from the drainfield area. 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 contact Tom
Klanchnik at (952) 461 -2356.
