The first design option entailed a 6000-gpd septic and secondary treatment system with subsurface disposal on the Vincent property utilizing the "Living Machine" secondary treatment technology specifically with a projected timeline of 18-24 months and a cost estimate of $324,000, (The "Living Machine' is a private design consultant/vendorthst is a separate entity from Innovative Design.) The second entailed a 6000-gpd septic and secondary treatment system with subsurface disposal on the Vincent property utilizing aState-approved secondary treatment technology stach as Orenco AdvanTex (see attached product brochure), with a projected timeline of 12 months and an estimated cast of $250,000. (Orenco AdvanTex is one example of a technology that is already approved by the State as a controlled demonstration system and that provides a level of treatment equivalent to that of "Living Machine" apparatus,) Staff did not recommend a system alternative that included no advanced secondary treatment component, Such a system (essentially a large scale conventional septic system), though much lower in cost (approximately), could not meet state treatment (nitrogen reduction) requirements applicable to systems having a treatment capacity in excess of 3000 gpd. Staff met with Commissioner liaisons Brown and Halkiotis on October 13 to brief them on the two design options and obtained agreement on returning this item to the full BOCC for decision at its first meeting in November, Since the meeting an the 13th, Staff has learned from the Living Machine representative that they are no longer available to join with the County as described under the first design option (See attached e-mail), Seemingly, Living Machine representatives have made a corporate decision to dedicate their time and effort on a pilot project in Guilford County that could eventually result in State approval of their technology. Their withdrawal from consideration presents the County with the second design option, as described above, which would incorporate a secondary treatment feature equivalent to the Living Machine, but which already has approval for use in North Carolina. FINANCIAL IMPACT: Capital project funds in the total amount of $250,000 have previously been allocated for the wastewater system at Northern, RECOMMENDATION(S): The Manager recommends that the BOCC authorize Staff to move forward with adesign/build option for the wastewater treatment system at Northern that features a 6000-gpd septic and secondary treatment system with subsurface disposal on the Vincent property utilizing aState-approved secondary treatment technology (such as Orenco AdvanTex).
