4 , <br /> �. H. KLEINFELDER & ASSOCIATES File No . S-2008-1 <br /> January 22 , 1973 <br /> PAGE THREE <br /> RECOMMENDED PERCOLATION VALUE <br /> Based on the percolation test results , we recommend an <br /> allowable rate of percolation of 4 gallons per square foot <br /> per day be used as a design value for dry wells or seepage <br /> pits , 25 feet in depth. The percolation capacity of a given <br /> dry well or seepage pit can be obtained by multiplying the <br /> percolation rate of 4 gallons per square foot per day by the <br /> circumferential area of the dry well or seepage pit . <br /> We trust that this report contains the information <br /> required .
