This disposal system is designed in conformance with the recommendations contained in "Nitrate Loading Study, Soil Suitability Study, Eagal Lake Recreation Complex", prepared by Don Chesney, R.E.A., of Valley Ag Research. The design is based upon the anticipated usage of 50 members and guests, each requiring a capacity o 15 gallons per day. The facility is planned to operate seven months each year, from April through October. ---- All materials and workmanship shall conform to the San Joaquin County Environmental Health Department Bulletin "Onsite Wastewater Disposal Standards" revised October,2003.

The septic tank shall have a capacity of not less than 2000 gallons. 2. The tank may be constructed on-site, to the specifications contained in the above referenced "Onsite Wastewater Disposal Standards", or it may be pre- fabricated, or two pre-fabricated tanks may be coupled together in series to achieve the required capacity. Plans for any proposed pre-fabricated tanks are to be submitted to San Joaquin County for approval. Plans shall address venting of inlet and outlet pipes, manhole locations, liquid depths, and all structural details. 3. Any fiberglass septic tank shall be set on a compacted sand bed and the surrounding excavation backfilled with clean sand, well compacted, to within 18 inches of the top of the tank.
