Mr. Mike Huggins, <br /> Supervising Environmental Health Specialist, of the San Joaquin County Environmental Health <br /> Department has indicated that he will require a raised disposal field because the ground water has- <br /> a tendency-to fluctuate and.rise during eriods'of the year. He indicated to our office that the <br /> Y gp Y .. <br /> ground water may come within 5 feet of the ground surface in that area. The Health Department <br /> desires a five foot of separation between the bottom of the disposal field and,ground water. <br /> From a soil suitability standpoint, the Site appears to.be suitable for a raised filter bed type of <br /> disposal field. <br /> 6.6 Required Size of Septic System <br /> According to the San'Joaquin County Sewage Standards(1996), the estimated size of the septic <br /> rsystem in a raised filter bed configuration is as follows. <br /> Base Tank-Capacity(BTC): 1,200 gallons. <br /> Average Daily Flow (ADF):.-194 gallons (from Section'3.6). <br /> Volume..(V): 1,200+ 194 gals = 1,394 gals (Septic Tank Volume). <br /> Soil Factor(SF): 0.250 (percolation test 10 min/in). <br /> rr <br /> `Leach-Line (LL): 1,394 gal x 0.250��97-Urner eet of LL. <br /> For filter Bed: =squ ' <br /> 349 LL x 4 (clayey.soils)-j1,39 �j <br /> Y <br />
