Omega Vineyard,Phase I <br /> Pa'ge No.4 <br /> 25'Seepage Pits: <br /> As indicated; the deep pit percolation test was performed using an alternate method where. <br /> „ the.full depth of the test hole {25' deep) i, percolated and a clear water rate is determined. The. <br /> clear water rate for'the 10.5.inch diameter test hole was 2.54.inches/minute. To convert the clear <br /> " water rate into the daily sewage capacity.(Cp)-of.a full sized seepage pit,the following formula,` <br /> was used:`. <br /> C,— �A'St"(6.23)4 Equation,(1-2). . <br /> r . . <br /> Cp — Allowable seepage pit capacity{25 foot deep),gal/day <br /> r = Clear water percolation rate for:test"hole; in./ruin.

E,. The required septic tank capacity is'as follows: <br /> Base Tank Capacity(BTC) . 1200 gals ; <br /> Average Daily Flow�(ADF) _ 350 gals <br /> TOTAL = 1550 gals, therefore use 1.600 gal tank <br /> III. Conclusi6n <br /> F <br /> k. Itis proposed to ixtilize two (2), 50 foot long leach lines.with a 25 foot deep by 42 inch <br /> ' diameter seepage pit on the end,of each line. Consequently, the total computed capacity of the. <br /> } -system is: <br /> Leach lines: <br /> Cl, = 60 gal/day <br /> Seepage Pits: <br /> Cpr. <br /> (3.0)(220 gal/day/pit) - 440 gal/day_ <br /> TOTAL — 500'gal/day > 350 gal/day (design) <br />
