SEPTIC TANK - 1,000 GALLON TANK REQUIRED
ABSORPTION FIELD
- SYSTEM REQUIRES 3' SEPERATION TO SEASONAL HIGH GROUNDWATER
- TEST PIT SHOWS 2' FROM EXISTING GROUND TO SEASONAL HIGH GROUNDWATER.
THEREFORE FILL WILL HAVE TO BE PLACED AND CONSOLIDATED PRIOR TO
CONSTRUCTING SYSTEM. 2Vt TO 3 FEET OF FILL REQUIRED.
- 15 MINUTE PERC. RATE IN NATIVE SOILS. USE FILL WITH SIMILAR PERC.
APPLICATION RATE= 0.8 GAL/DAY/SQ.FT,
330 GAL/DAY + 0.8 GAL/DAY/SQ.FT. = 413 SQ.FT. REQUIRED
