July 28.20 <br /> Pagr 3 <br /> ' See attached tables for actual weekly and monthly attendance rates versus water <br /> usage computations. <br /> " The average daily gallons per person in both 2002 and 2003, was generally, 3 ounces. The high <br /> est wastewater generation rate was 200 gallons per day. Water usage is easily tracked because a <br /> 1900 gallon holding tank is currently being used for our waste water system and is pumped by a <br /> registered hauler. <br /> "' In order to get an idea of how much waste water would be generated by a daily Learning Center <br /> (proposed) we tracked wastewater during our Vacation Bible Club July 12 -16. Daily attendance aver <br /> aged 220. Students were on site from 8:30 am - 12:30 (4 hours). The wastewater generated was <br /> 400 gallons per day. This amounts to 1.8 gallons per day per person. <br /> Proposed Water Usage Computation - Phase I <br /> Building #1(current) -Multipurpose Building #2(proposed) - Learning Center <br /> Sat/Sun (total attendance) 800 100 <br /> Mon-Fri (total attendance) 200 625 <br /> De-nitrification Factor <br /> As stated in the October 7, 1999 Soil Suitability/Nitrate Loading Report the soil de-nitrification factor <br /> is estimated at 25% due to the gray clay <br /> Nitrate Load Estimate <br /> If we use SJC onsite waste water disposal standards (October 2003) water use <br /> computation factor table for commercial establishments of 10 gallons (Church with kitchen) PPPD <br /> for Building 1 and 15 gallons (day school) PPPD for Building 2, we still estimate that nitrate load <br /> will fall below the drinking water standard of 10 mg/I - N. If, however we use The Home Church <br /> daily average of 3 ozs per person (Church) and 1.8 gals per person (Learning Center) the Nitrate <br /> load falls far below the standard. <br /> Note: In a phone conversation in February of 2003 with a City of Stockton employee at the water <br /> treatment plant it was discovered that they estimate the averse 3 bdr house to have about 300 <br /> gallons a day waste water which comes to about 9,000 gallons a month. Current (June 2004) waste_ <br /> water flow at The Home Church is about 4,000 gallons a month. Even if current usage is doubled <br /> (our best estimate) it would still not even be equal to a single family residence <br /> Chemical Analysis of Current Waste Water <br /> A chemical analysis of our waste water system was done by FGL and L on 3/15/04.
