SEPTICSYSTENT CONSTRUCTION All septic system requirements must be in accordance with the San Joaquin County Environmental Health Se�va(_7e Standards. For gravity systems, the house Pad HILISt be raised to permit gravity flow through both septic tanks and into leach field. The double septic system design shown on this plan must comply with the followlria:(Sec. 10 Sewage Standards.) MIN. 25' DEEP SEEPAGE PITS (TYP.) NlunInUin distance from well to seepage pits 150' Minimum distance from trenches to well 100, Nlinuni-im distance from foundations,driveways and pools 10, Nlaxiinum length of individual leach line 100, NlaxiMUM width of trench 24" Maximum grade of line 3"per 100' Preferable grade of line 2"per 100' Distance between lines 10'edge to edge NlinirnUrn depth of rock below approved perforated pipe 12" Minimum depth of rock over approved perforated pipe 2" Maximum depth of trench 42" Nlinnnum distance between leach line and septic tank 5' I I LEACHLINES AND TRENCHES Nfaximurn soil cover over leach line 24" (TYP. -MIN, 10' EDGE TO EDGE) Minimum soil cover over leach line 6" During leachfield construction,die sidewalls and floors of the leachline trenches must be scarifie&o open smeared soil surfaces possibly caused from the backhoe excavations. Seepage pits are normally scarified by a"cleat"on the outsize of the auger flight. All excavations Should be inspected by a representative from San Joaquin County Public Health Services Department Environmental Health Division, before placement of drain rock. Telephone at least 48-hours in advance cf inspection (209) 468-3284. Leachl.-teld areas cannot be driven or parked over,and no structures can be built over these areas. Final grading of the leachfields must be such that drainage water from domestic irrigation or rainfall cannot collect and pond over tlz, leachfields. Only grasses and small slinubs may be planted over the fields,with trees and large shrubs planted at least 15 feet away. The designated replacement area Must remain as such,with no permanent structures built in this area. SEPTIC SYSTENT iNTAINTENANCE The septic system installed for the respective residence must consist of a dual leachfield system in accordance with San Joaquin Sewage Standards,Section 10.1. For the system to have maximum theoretical longevity,the leachfields must be manually switched between each other on an annual basis.This can be accomplished with a push-pull"gate"valve,which v/ill be on each of the two effluent lines DISTRIBUTION BOX(TYP.) 0 DISTRIBUTION UT exiting the secondary septic Link. It may be a requirement by the Environmental Health Department that the valves be located within SECONDARY SEPTIC TANK 0 PRIMARY (TYP.) the second compartment of the secondary tank. This second compartment must also have an installed filter. BULL RUN VALVE o (SEE ATTACHED NOTES) (OR), 0 TANK The Environmental Health Department will require that the tanks be pumped every three years. Therefore,access to the tanks by pumper (IN CHRISTIE BOX) trucks must be maintained.Since the septic systems will be installed in fine-grained clay soils,sodium from a water softener may hasten 0 the clogging mechanisms of this soil type,which may lead to septic systern failure. Therefore,water softeners should be avoided or PRIMARY SEPTIC TANK limited in use. Water from domestic irrigation or rainfall must not be allowed to congregate in the leachfield areas. 0 By signing below,the homeowner has read and understands the constniction and maintenance p-ocedures,as stated above and agrees to perform these recommended procedures.
