New Lake Hartwell Water Treatment Plant

Ardurra delivered design and construction services for a state-of-the-art 3.0 MGD grassroots membrane water treatment plant, 5.0 MGD raw water intake, and 10,000-foot raw water transmission main serving Fair Play's growing water demands. The facility features advanced pretreatment using chemical addition, rapid mixing, flocculation, and high-rate sedimentation, followed by membrane microfiltration with on-site hypochlorite generation for disinfection.

The sophisticated water treatment plant utilizes PLC-based distributed control systems, while the raw water intake was constructed using the sinking caisson method with a 520-foot intake line installed via horizontal directional drilling. Comprehensive planning included financial feasibility studies, water treatment optimization, and extensive characterization of raw water quality to support optimal design decisions.

Key Project Components:

• Designed 3.0 MGD grassroots membrane facility with advanced pretreatment and microfiltration expandable to 5.0 MGD capacity

• Constructed 5.0 MGD raw water intake using the sinking caisson method with horizontal directional drilling for a 520-foot intake line

• Conducted feasibility studies evaluating wholesale water purchase versus treatment options with site selection analysis

• Performed membrane pilot study using pressurized membranes with long-term raw water quality sampling and characterization

• Managed extensive permitting activities with the U.S. Army Corps of Engineers and SCDHEC, ensuring regulatory compliance

• Designed integrated systems including pretreatment, membrane filtration, 1.0 MG finished water storage, pump stations, and chemical feed systems

• Constructed 13,000 SF treatment building housing membranes, chemical feed systems, and finished water pumping infrastructure

The facility provides Fair Play with reliable, high-quality water treatment capacity while demonstrating innovative membrane technology applications. Comprehensive planning and advanced treatment processes ensure long-term operational efficiency while supporting community growth and water quality objectives.
