Although there was no definable trend in comparison between the two sets of perc tests (east vs. <br /> west), the test results reveal favorable perc rates, except for the 24-inch test in the east portion <br /> which had a comparatively slow perc rate at 50 min/in. The perc rate for the 24-inch test for the <br /> west area was 19.2 min/in, illustrating the incongruity between these two tests. Consequently, <br /> Table 4 illustrates the averaging of the two sets of perc rates and application rates to arrive at <br /> average permeability and average infiltration rates for the entire future disposal area. <br /> A summary of the perc test results with corresponding application rate in gallons of effluent <br /> accepted per square foot, per day are found below in Tables 2 and 3. <br /> TABLE 2 <br /> WEST PERCOLATION TEST RESULTS <br /> WITH CORRESPONDING APPLICATION RATES (gallons/ft'/day) <br /> t <br /> 24 INCH DEEP PERC TEST BORING19.2 'n/inch / 0.671 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> D <br /> 36 INCH DEEP PERC TEST BORING 28.8 'Kinch / 0.567 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> 42 INCH DEEP PERC TEST BORING 9.3 'n/inch / 0.857 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> 60 INCH DEEP PERC TEST BORING 5.7 'n/inch / 1.029 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE �'�_ <br /> Application Rates adapted from California State Water Resources Control Board Guidelines for the Design of Sewage Systems. <br /> TABLE 3 <br /> EAST PERCOLATION TEST RESULTS <br /> WITH CORRESPONDING APPLICATION RATES (gallons/ft'/day) <br /> 24 INCH DEEP PERC TEST BORING 50.¢min/inch / 0.417 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE -' <br /> 36 INCH DEEP PERC TEST BORING 9.6,min/inch / 0.971 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE J <br /> 42 INCH DEEP PERC TEST BORING 19.y min/inch / 0.764 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE l <br /> 60 INCH DEEP PERC TEST BORING 11.4 min/inch / 0.786 gallons/ft'/day <br /> PERCOLATION RATE/APPLICATION RATE <br /> Application Rates adapted from California State Water Resources Control Board Guidelines for the Design of Sewage Systems. <br /> Page-6- <br /> Chesney Consulting <br />
