Only in the months of December and January, and possibly November and February would deep percolation potentially occur. This data illustrates a relatively high potential for there to be significant evapotranspiration (or bare soil surface evaporation). III. NITRATE LOADING STUDY FINDINGS A. WASTEWATER FLOW VOLUME PROJECTIONS AND CHARACTERISTICS Wastewater Flow Volume Projection Wastewater loading projections are based on peak occupancy of the maximum or total number of patrons (private club members), guests and employees on days the faciliis open. The initially estimated number of on-site personnel classifications of 50 members has'ot changed dramatically since May 2012, when Doug Noteware, PE calculated the wastewater disposal system. This member number applies to the day-to-day average of on-site people during the spring and summer season (April through September- 6 mos.) the facility is open. What is expected to change, is the addition of the Hospitality Room to the existing Clubhouse, thus causing an indeterminable increase in the number of on-site people. ----------- - Chesney Consulting
