Therefore: <br /> F= 8.26 ft <br /> D= .667 ft <br /> L= 22.0 ft (start of test) + 13.7 ft (end of test)= 35.7 + 2= 18.5' <br /> t= 4 hrs <br /> Q = 20 X 8.26 X .667 = 1.54 gals effluent/sq ft/day. <br /> i 17.9 X 4 <br /> If each leach field was designed with six - 60" X 23' pits, the total daily absorption rate would <br /> be: <br /> 60" X 23' pit= 361.1 sq ft X 1.54 gals effluent X 24 pits= 13,346.3 gals/day. <br /> With the data presented, design factors such as the number of urinals, commodes and wash <br /> basins per restroom can then be formulated. It is highly recommended that the lowest water <br /> volume_ for flushing and washing be incorporated into the design. Each restroom should be <br /> monitored closely to ensure that it is not "overloaded". In addition, it will be a requirement <br /> fi from the Environmental Health Department that County approved chemical toilets be made <br /> I` available immediately for temporary use if any of the four restrooms become inoperable, until <br /> repairs of the restroom systems are completed. Any repairs will have to be inspected by the <br /> Environmental Health Department. <br /> Climatic Stress <br /> In addition to estimating wastewater loading rates, climatic stress must also be taken into <br /> consideration with regard to the loading of the septic system. Leachfields must transmit two <br /> hydraulic loads: the effluent load and the climatic load during the rainy season. It is <br /> anticipated that the effluent load for the Open Air Mall will continue to increase as its <br /> popularity grows. Conversely, the climatic load which is defined as the infiltrated precipitation <br /> minus evapotranspiration losses, can be extremely variable, as we have witnessed locally in the <br /> last six years. <br /> 6 <br /> �Jj <br /> Valley Ag*search <br />
