Speaker: modern compact treatment technologies could shrink acreage needs to a fraction of committee criteria
Summary
A public commenter argued newer technologies (moving bed biofilm reactor / MBBR) can reduce a wastewater plant footprint to about five acres and avoid the 60-acre minimum the committee used.
Terry Monaghan told the committee that technology choices affect land needs and urged consideration of closed, modern systems that require far less acreage than conventional open-basin plants. "There's newer technology, and that technology only requires 5 acres for the water treatment plant plus odor taking care of odors," Monaghan said, advocating moving-bed biofilm reactor (MBBR) and similar enclosed systems.
Monaghan acknowledged higher capital costs for compact technologies — "13–15% more" in his estimate — but said those costs may be offset by avoiding land purchase, road improvements and off-site works required at larger county sites. Committee members noted the review of alternative technologies was outside the committee's specific charge to score sites meeting a 60-acre threshold, but several public commenters asked council-level analysis to include such alternatives.
