The calculations above exclude the infiltrative surface of the sump disposal structure, which will <br />act as additional area for the management of effluent as the filter bed ages and/or under extreme <br />hydraulic stress. <br />It is recommended that the kitchen sink should not have a disposal. All food waste should be <br />handled as solid waste and disposed of in the garbage. <br />Domestic water use and irrigation water use over the filter bed area must be kept to the lowest <br />volumes possible. For example, laundry should be done throughout the week and not just on <br />weekends. When draining bathtubs, the water should be drained very slowly. <br />Consideration should be given to pumping the septic tank every three years to mitigate nitrogen <br />loading by extraction of septage. <br />LIMITATIONS <br />The findings, opinions, calculations and conclusions of this report are based upon information <br />from standard engineering and analytical/physical test procedures, contemporary scientific <br />literature and agency consultations. Information used in these studies is deemed reliable by the <br />sources from where it was obtained. <br />This report is based upon current scientific knowledge to assess factors which are extremely <br />variable and complex within the environment. Although there are several methods to predict <br />environmental impact from a septic system, San Joaquin County Environmental Health <br />Department Onsite Wastewater Treatment System Standards and requirements have been <br />employed for these purposes, and for this project. Therefore, no guarantee or warranty is <br />expressed or implied concerning any aspect of this report, or for the prevention of environmental <br />impact.
