With two bedrooms, this new structure will have a design sewage flowrate of 240 gpd per 15A NCAC 18A .1949 (a). Accordingly, the design sewage flowrate for the proposed pastoral retreat will reduce residual available capacity in the sand filter LPP system, once connected. Other Septic Systems Usage data was not provided for other septic systems on the property; hence, we are unable to assess available capacity in any septic system other than the sand filter LPP system at this time. A similar pumped volume analysis could be utilized to assess available capacity in the staff residence (Falcon), but installation of water meters would be required for accurate assessment of all other systems due to their gravity dose designs. V. Summary The sand filter LPP system currently has residual available capacity of 666 gpd, and this available capacity could be significantly increased (possibly up to 1,397 gpd) with the addition of FIE technologies. Further, additional residual capacity may be available in other existing septic systems on the property, but detailed analysis of these systems is required for accurate assessment. 5 94
