Mooresville approves $1.27 million task order for wastewater plant expansion planning
Summary
The board approved Task Order No. 3 with Black & Veatch to continue environmental review and permitting toward expanding the town's wastewater treatment capacity from 7.5 MGD to 12.5 MGD; the contract increase and $700,000 appropriation from reserves were also approved.
The Mooresville Board of Commissioners approved a $1,273,440 task order to Black & Veatch International Company on March 3, 2025 as part of planning and permitting for a proposed expansion of the town’s wastewater treatment plant.
Public Utilities staff told the board the town has been evaluating options including expanding its plant and pursuing an interbasin transfer certificate to discharge to Lake Norman, coordinating with an adjacent utility to send untreated wastewater offsite, or other alternatives. Staff said the recommended path is to expand the current plant from 7,500,000 gallons per day (gpd) to 12,500,000 gpd and to pursue the state interbasin transfer process administered by the Environmental Management Commission.
The task order funds preparation of an environmental impact statement and the interbasin transfer application. The task order of $1,273,440 increases the overall Black & Veatch master agreement to a not‑to‑exceed amount of $2,904,590; the board also approved a project ordinance amendment to appropriate $700,000 from utility capital project reserves.
Public Utilities presenter (Miss Craft) reminded the board that initial planning estimated roughly $5 million for the overall process and said the contract increase is consistent with prior expectations. The work plan cited multiple steps for public and stakeholder involvement during permitting.
Commissioner DeWeese moved approval of Task Order No. 3 and the associated project ordinance amendment; Commissioner Keriker seconded. The motion passed on a recorded vote of 6–0.
Staff said the expansion, if pursued, would include preparation of environmental documentation and state permitting; any construction or final decision would follow additional approvals and public processes.
