Marion County officials are moving forward with plans to expand the utilities capital improvement program, which will include significant changes to the existing wastewater treatment facility. During a recent workshop, commissioners discussed the expansion's footprint, which will shift westward, away from nearby neighborhoods. This decision aims to minimize the impact on local residents while enhancing the facility's capacity.

The expansion will introduce new biological unit processes, including additional round tanks, which are designed to improve wastewater treatment efficiency. However, some existing structures, referred to as "ribs," will remain unchanged. The county owns a 10-acre tract adjacent to the current facility, which will serve as the primary site for construction. There is also a non-owned parcel further west that currently acts as a buffer but could be developed in the future.

Commissioners expressed concerns about odor management associated with the facility's operations. Plans are in place to cover certain units, such as the EQ surge tank, to capture harmful gases like hydrogen sulfide. However, officials noted that not all units will be covered, as this could complicate maintenance and potentially hinder biological processes.

The discussions highlighted the county's commitment to balancing operational needs with community concerns. As the project progresses, officials aim to ensure that the expansion remains as unobtrusive as possible for neighboring residents while enhancing the overall functionality of the wastewater treatment system. The next steps will involve further planning and community engagement to address any ongoing concerns about the facility's impact on the surrounding area.
