SANITARY SEWER <br /> Since there is no sanitary sewer system serving the area, the effluent <br /> disposal will have to be accommodated on-site. Valley Ag Research has <br /> conducted a nitrate loading study as required by the San Joaquin County Health <br /> Department to determine the effects of employing a conventional septic system <br /> and leach field to dispose of the effluent. This study indicates that the existing <br /> nitrate levels are low enough that a conventional leach field system can be <br /> utilized for the lower flows associated with phases one and two. However, due to <br /> the high ground water levels a mounded leach field system would have to be <br /> constructed. <br /> Phases one and two of the construction would require sewer capacity for <br /> 550 seats. Based on the San Joaquin County Environmental Health standard for <br /> churches with no kitchen, a flow rate of 5 gallons per seat per day is required <br /> which correlates to 2,750 gallons per day (gpd). This quantity of effluent can be <br /> disposed of through traditional mounded type leach fields. However, the ultimate <br /> build-out would require sufficient capacity for 2,000 seats, which corresponds to <br /> a flow of 10,000 gpd (this flow would occur on Sundays only). This quantity of <br /> effluent will require a small on-site treatment plant in order to avoid heavy nitrate <br /> loading of the soil. The disposal system for the ultimate build-out will be modified <br /> to include a large holding tank to allow the effluent to be stored and evenly <br /> distributed throughout the week. This will allow the leach field constructed with <br /> the initial phases to be utilized during the winter months. During the dry summer <br /> months, a sprinkler irrigation system will be utilized for disposal of the effluent. <br /> Employing a dual system such as this will allow the softball field area to <br /> utilized as the storm drain basin in the winter months while the leach field <br /> disposes of the effluent. In the summer months the landscaped and lawn areas <br /> can be irrigated with the treated effluent which will not only help to conserve <br />
