ATLANTA — Construction of large-scale expansions to the Big Creek Water Reclamation Facility in Roswell, Ga. is underway which will upgrade capacity of aging infrastructure and accommodate future population growth.
The $300 million Fulton County Department of Public Works’ project, the largest single capital expansion project in Fulton County’s history, is being delivered by the design-build joint venture of Archer Western and Brown and Caldwell. Construction is expected to take 46 months and conclude in 2024.
When the plant was originally constructed in 1969, it had a treatment capacity of roughly 0.75 million gallons per day (MGD). To keep up with the region’s exponential growth over the years, it has been expanded to 24 MGD, indicates a release, adding as numerous areas of the facility near the end of useful life and in anticipation of further population increases and economic development, the facility is being upgraded and expanded to a capacity of 32 MGD.
The project includes coarse screening and grit removal, primary clarification, biological nutrient removal, flat plate membrane filtration, offline equalization tanks, aerobic digesters, new electrical and instrumentation infrastructure, and ultraviolet and post-aeration of effluent.
The team has designed the project to reduce light, noise and odour from leaving the facility and provide significant quality of life improvements to the surrounding neighbourhood. The new treatment process, incorporating state-of-the-art membrane technology, will produce significantly cleaner water than the existing plant, adds the release. Discharges to the river will be reduced by up to 50 per cent from current permit limits, even at the higher flow capacity.
Construction crews will also demolish and repurpose various older or underused sections of the facility and efforts will be made to recycle existing site materials, eliminating up to 10,000 truckloads of landfill disposal.
“Fulton County is committed to protecting the Chattahoochee River, our most important natural resource. This important, landmark project reflects our dedication to providing the highest quality services to our citizens in an environmentally sound way while still allowing the growth and economic development throughout the North Fulton County area,” said Fulton County Public Works director David Clark in a statement.
