With two bedrooms, this new structure will have a design sewage <br />flowrate of 240 gpd per 15A NCAC 18A .1949 (a). Accordingly, the design sewage <br />flowrate for the proposed pastoral retreat will reduce residual available capacity in the <br />sand filter LPP system, once connected. <br /> <br />Other Septic Systems <br />Usage data was not provided for other septic systems on the property; hence, we are <br />unable to assess available capacity in any septic system other than the sand filter LPP <br />system at this time. A similar pumped volume analysis could be utilized to assess <br />available capacity in the staff residence (Falcon), but installation of water meters would <br />be required for accurate assessment of all other systems due to their gravity dose <br />designs. <br /> <br /> <br />V. Summary <br /> <br />The sand filter LPP system currently has residual available capacity of 666 gpd, and this <br />available capacity could be significantly increased (possibly up to 1,397 gpd) with the <br />addition of FE technologies. Further, additional residual capacity may be available in <br />other existing septic systems on the property, but detailed analysis of these systems is <br />required for accurate assessment. <br /> <br />94
