LEACH AREA DESIGN
3 Bedrooms x 2 persons/bedroom = persons
/O Persons x 55 gallons of wastewater/person/day = 330 total gallons of
wastewater/day.
Percolation Rate: ;F. 0 min/inch
Gallon of wastewater/square feet of leach area for a Percolation Rate of:
2. 0 min/inch = 2.5 Gal/SF Sidewall Area
�. 0 Gal/SF Bottom Area
* If a leach bed is to be installed, no sidewall is allowed.
* If percolation rate exceeds 20 min/inch, no bottom area is allowed.
- SEPTIC TANK -
* WITHOUT GARBAGE DISPOSAL:
Gallons of wastewater/day x 150% = REQUIRED effective liquid
capacity of septic tank.
RECOMMENDED: Septic Tank
