ffst will travel to the septic tanks, with effluent flow from the tanks,the followingescribes the operation of the septic system for both the residential-structure and the,ery: Influent ftertl the house will gravity flowinto an existing 1,200 gallon tank. 'three tend frorn"Ais tank)n a southwest direction. The tightline from this_tank will be routed to gravity flow to a ne 2,0 . llon, single compartment septic tank, with filtration. Winery influent will also gravity flow t4 . hs. The combination of the winery and residential domestic wastes will gravity to an existing(l,600 allon, two compartment tank. The second compartment of the 1,600 gallon tank is to be the purfap, amber to pressurize the effluent for even distribution throughout the filter bed. This residential 1,200 gallon tank and the 2,000 gallon combination tank will provide preliminary treatment and trap paper, etc. The tank must be pumped on a prescribed interval basis depending on direct observations of paper and scum accumulation; e.g., every�six—ntgnths to every three years, depending on sludge/scum accumulation. Peaking factors for users on septic tanks vary with usage during the hour of the day, and day of the week. Peak hourly rates are associated with normal working hours. The ratio of the peak day to the average day can vary from 1.5 to>5, depending upon the usage. However, peaking factors are not as relevant since the effluent pump will dose on demand. A peaking factor of 2.5 (average between 0 and 5) will be used in the calculation below: Septic Tank Hydraulic Detention Time Doemion'rime= 1,200 Residential Tank+2,000 Combination Residential and Winery Tank+ 1600 Pump Chamber Tank x 0.70 (30%volume lost to sludge/scum accumulation)+ 2.5 (Peaking Factor)x 540 gaWday ADP Detention Time = 2.5 days. The minimum acceptable detention time is 1.0 days. Therefore, the septic tankage volume is adequate.
