I S i,1) 1j3 <br /> 8 <br /> this method for determining acceptable hydraulic loads. This test was conducted over <br /> a three-day period to ensure that the soil conditions were near saturation at the <br /> time of the measurement. <br /> Based on field and lab analysis, the monthly drainage through the soil was <br /> determined to be approximately 4.5 inches. The volume of rainfall used to calculate <br /> the water balance is a statistical iteration using a mean+ standard deviation <br /> condition. This will allow for 90% of the rainfall conditions in the area. The <br /> maximum loading onto the site should be approximately .8 of an inch per acre per week <br /> and the hydraulic application rate should not be excessive if the water balance <br /> calculation is used appropriately. Antecedent moisture conditions should not limit <br /> the use of the site unless the soil has been saturated or the ground is frozen. The <br /> waste application is conservative. <br /> Conclusion <br /> A slow rate spray irrigation of the Bradshaw Mobile Rome Park in Orange County, <br /> North Carolina appears to be a workable alternative. . The system could be designed to <br /> apply approximately .8 inches of water/acre/week and the rate should not exceed .35 <br /> inches per hour. If the system is designed appropriately, it should provide <br /> long-term treatment and renovation of the wastewater generated at this facility. A <br /> preapplication treatment system must be provided which adequately treats the waste <br /> and stabilizes it in an acceptable manner prior to irrigation on the land. In <br /> addition, some surface storage will be required to allow for waste generated during <br /> periods of excessive rain, freeze, or the sporadic snowfall conditions. Wastewater <br /> should not be applied to the soil when the soil is saturated or when it is frozen. <br /> Careful operation o this facility should provide a long-term acceptable wastewater <br /> treatment system for the Bradshaw Mobile Rome Park. <br /> I <br /> 1 I <br /> 1 <br />
