3 % Water savings from low flow fittings = Typical Crush Weekend Event people count serviced by this system = Event daily domestic waste flow = Winery Dimestic Flow = Typical Non Crush Weekend Volumes Event people count serviced by this system = Event daily domestic waste flow = Winery Dimestic Flow = Typical Weekday Volumes Event people count serviced by this system = Event daily domestic waste flow = Winery Dimestic Flow = Combined Winery Waste Flow Summary The proposed system will be designed to treat process waste from a 5,000 gallon per year winery & the associated domestic waste. Wine Production = Crush Duration = Peak Process Waste Flows During Crush = Average Process Flows (non crush) = Additional Process Flow = Total Design Peak Process Waste Flows = Winery Process Waste Flow Calculations Winery Domestic Waste Flows 5000 gal/wine/yr days (30-60) 25 ((1.5 x production)/crush days) gal/day ((5 x production)/days in yr) (usually 0) 25 0% percent 2 # 2 # 15 # gal/day 9 8 # 7.50 gal/day gal/day gal/day 6 # gal/day gal/day Total Domestic Waste Peak Flows = 9 7 of 82

SOIL TYPE IS CLAY LOAM WITH MODERATE GRANULAR STRUCTURE 2. BASED ON SOIL TYPE THE INFILTRATION RATE = 0.25 GAL/SF/DAY 3. USING INFILTRATOR CHAMBERS, THE NET ABSORPTION AREA PER LINEAR FOOT OF TRENCH = 3 SF/LF 3. THE WINERIES EXPECTED PROCESS WASTE IS 250 GALLONS PER DAY, WHICH WILL BE PROCESS VIA THE PROPOSED 2000 GALLON HOLD AN HAUL TANK SYSTEM. THE REQUIRED STORAGE IS 7 X 250 GAL = 1750 G. 4. THE WINERIES EXPECTED SANITARY WASTE IS 105 GALLONS PER DAY 5. THE TOTAL EXPECTED GALLONS PER DAY TO THE WINERY LEACHFIELD IS = 105 GAL/DAY 6. THE MINIMUM TOTAL LENGTH OF TRENCH REQUIRED TO TREAT THE EXPECTED EFFLUENT IS 105 GAL/DAY / [(0.25 GAL/SF/DAY) X (3 SF/LF)] = 140 LF RESERVE WASTEWATER CALCULATIONS 1. SOIL TYPE IN THE TRENCH ZONE IS CLAY LOAM WITH MODERATE GRANULAR STRUCTURE 2. BASED ON SOIL TYPE THE INFILTRATION RATE FOR DRIP = 0.6 GAL/SF/DAY 3. THE WINERIES EXPECTED PROCESS WASTE IS 250 GALLONS PER DAY 4. THE WINERIES EXPECTED SANITARY WASTE IS 105 GALLONS PER DAY 5. THE TOTAL EXPECTED GALLONS PER DAY FROM THE PROPOSED WINERY = 355 GAL/DAY 6. THE MINIMUM DISPERSION FIELD AREA FOR AN ENGINEERED DRIP SYSTEM GIVEN THE ABOVE VARIABLES IS (355 GAL/DAY / 0.6 GAL/SF/DAY X 200%) = 1183 SF DOMESTIC SYSTEM NOTES & DETAILS 4
