Forsyth County officials will hold a ribbon cutting ceremony at 2 p.m. on Friday, June 12, for a recent expansion at the Forsyth County Water Treatment Plant (2255 Antioch Road) in north Forsyth. The expansion at the facility increased the peak water treatment capacity from 33 million gallons per day (MGD) to 40 MGD.

“These upgrades strengthen our ability to meet Forsyth County’s evolving needs while maintaining the high standards of water service that our residents expect,” said Department of Water & Sewer Director Scott Adams. “By increasing capacity and upgrading key systems, the Antioch Water Treatment Plant is better positioned to continue delivering safe, reliable drinking water today and well into the future.”

On average, the Forsyth County Water Treatment Plant currently produces over 14 MGD of safe, clean drinking water every day using a unique balance of conventional, membrane and ozone filtration technology systems. Together these systems provide a high degree of flexibility for handling seasonal water demands and water quality changes. During a time of high demand in 2025, the Forsyth County Water Treatment Plant produced 30 million gallons of water in a single day. 

The following improvements were made to enable the increase of water treatment capacity:

• Addition of a new flocculation and sedimentation basin and flow control vault
• Addition of three new membrane trains and associated equipment in existing tanks
• Addition of a Sodium Hydroxide Chemical Storage Tank
• Addition of a 700-HP finished water pump
• Addition of new sludge collection systems in the filter and membrane backwash basins

Additional improvements made to the facility:

• Addition of a new baffle wall to the raw water tank to improve water quality consistency
• Addition of a new filter gallery enclosure to improve the ability to maintain the conventional filter pipe gallery

Construction of the Forsyth County Water Treatment Facility upgrades was provided by PC Construction. Funding for the expansion was provided by the Forsyth County Department of Water & Sewer and total costs for the project were approximately $21 million.
