No wastewater pond is proposed at time, the process wast water treatment for this <br /> small winery facility will be accomplished using a tank system. The domestic wastewater flow is minimal. 13ven at <br /> peak times we anticipate a design flow of maximum 30 gpd (2 winery workers at 15gpd per person per EPA design <br /> manual). We believe that the minimal domestic flow can be treated and disposed of utilizing the existing septic system <br /> onsite, which was designed for much larger flows. Domestic wastewater will be treated completely separate from the <br /> process wastewater. <br /> Please do not hesitate to contact us anytime with any comments or questions you may have I am looking forward to <br /> discussing this project with you further. <br /> Sincerely, <br /> Hubertus G.
