C. WASTEWATER,DISPOSAL SYSTEM OPERATIONAL PARAMETERS AND COMPONENTS SSS§:3.7: The design of pressurized chambered filter bed disposal system-for the Winery facility 1� :. f is based upon the factors.of efficient operation, disposal field longevity, and environmental''protection. --An overview of the system operation is as follows: Influentwaste from each-of the buildings referenced on Pages 14 and 15 will enter standard septic tanks.that have'yet-to be installed next to existing lift stations. effluent from these tanks will then gravity-'flow into these existing lift stations to be pumped to another existing lift station, directly north of the°Office Trailers.`4This lift station is used to pump influent up t on the mound system.✓It,is now proposed to use this lift station to pump clarified effluent ,500 fee to the east to the new disposal are Here, the pumped f' effluent will enter the first compartmen o a standard concrete Z aU11 ^nz monolithic, two compartment septic.tank to primarily reduce the energyof the pumped effluent. The second compartment will settle any carryover particulate matter: An efflue films shall be installed in this second compartment. From this second compartment; the effluent will gravity to a standard concrete 1,200i-gallon, monolithic, single compartmentseptic pump chaml�r.tank This' ump chain er tank -will have an Orenco BioTube filter vault, with a�dunlex pumn system to pump and pressurize the effluent. The two pumps wiU alternate between six chambered filter bed cells, as depicted on the Site Plans.' . 1a As calculated below, each chambered filter bed cell is to be 34A east-west with a total of 13 rows of chambers north.-to-south...As noted, each chamberJi actually 53 inches.long, but when connected together, the usable length is 4 ft (4 ft x 8 chambers +2 ft end caps='34:ft). Each cell is: 34 ftE-W x (13 laterals w/34 inch wide chambers +.6 inch separation-43.3 ft North-South/cell) x 3 cells N-S = 130 ft N-S. Total number of chambers — 8 chambers-per lateral E-W x 13 chambers/cell = 104 chambers/cell x six cells — 624 chambers. Reviewing the percolation rates,and more particularly the application rates illustrated in Table 2 on -`Pa e 7 we find an average application rate of 0:4°87' allons/ . - a tit at can-the r tically be accepted g � g PP $- ��t throughout the soil profile. Each dose volume is calculated t e 186 gals (See P : 20) dependent upon the float settings.; If we take a maximum theoretical single dose o , deposited equally over one filterbed. cell of 971 sq.ft (area under 10.4 chambers,,one-sixth the total number), the application rate is: 186 gals 971 ft' = 0.192'gallons/ft2 x (13.4 doses/day- 6`cells =.-2.2 doses/day/cell) = 0.422 galloxis/ftJday,_or comparable to the soil pxofile application rate. C TANKS SEPTI Septic tanks store the accumulated sludge, scum and effluent(clear zone)volumes, which in turn affect treatment of nitrogen within the tanks, as documented in this study. In the following calculation, the retention time for effluent within the septic tanks is determined to be approximately one day, which is acceptable. It is noted, that each building will:have its own septic tank to capture and_ret.ain solids before pumping to the last lift station. The volume of these.tanks have not been :taken into consideration_in the.calculations below. Only thelastlift_station of approximately 1,000 gallons; the 2,000-gallon tank adjacent to the disposal area,-and-the 1200..gallon dosing/pump - ... chamber tank are used in the following calculation:= Chesney Consulting
