r <br /> Soil Suitability&Nitrate Loading Study Page 4 <br /> St. Patrick's Church, Escalon, CA <br /> Project No. 607.1 <br />" October 14, 2009 <br /> Based on these records, it appears the septic systems in the nearby area have <br /> operated consistently and with few repairs needed. <br /> 3.3 Existing and Proposed Septic System Usage <br /> In the near future, a new chapel will be constructed, which will be served by a <br /> new, dedicated septic system. The proposed new septic system for the chapel is <br /> expected to experience minimal used limited hours of use. The proposed <br />_ -' chapel will have a seating capacity <br /> 4 60 p6sons. It will have two restrooms, <br /> each with two toilets, and one of the t ' ets in the men's room will be a urinal. <br />+ The San Joaquin County Sewage Standards (EHD, 2003) offers guidance for <br /> assumptions regarding septic flow rates. Accoxdi Table 6.1.,15, the <br /> �-- assumption is made that a church will prod ce 5 gal ons per day at <br /> . : <br /> Using this assumption, the 60-seat chapel is rodu e 300 gallons- <br /> per-day (GPD) of raw sewage, 5 days each week. <br /> For residential septic systems, the assumption is made that each resident <br /> produces 70 gallons per day (GPD) of sewage. Permanent esi ence are <br /> generally assumed to have 5 residents, yielding a sewage outpu of 350 GPD In <br /> F1 this case, the existing 2-bedroom house is occupied by the pari and <br /> j given the requirements of the Catholic faith, the house is un ' e y to hou as <br /> many as five residents. The house estimate is therefore re du ed to 200 GPD. <br /> �1 <br /> t When the other proposed buildings are completed in the more uture, a <br /> large new septic system will be constructed to serve all of those buildings, <br /> F although the future rectory could also be served by the existing residential <br /> k system.
