Walker County Water & Sewerage Authority (WCWSA) is implementing one of the most comprehensive water system expansions in the region—more than $74 million in improvements—to support major development on Lookout Mountain, extend potable water to historically unserved rural communities, and strengthen regional reliability through coordinated operations with neighboring utilities. This program integrates a GEFA-financed Water Treatment Plant (WTP) upgrade with a $54 million ARP-funded distribution and storage initiative administered by the Georgia Office of Planning and Budget (OPB), forming a unified, long-term strategy for delivering water across some of the most challenging topography in the Southeast. The GEFA-funded WTP improvements expand future firm capacity to 15 MGD through filtration upgrades, chemical feed modernization, SCADA enhancements, and high-service pumping improvements. A new 4-MG clearwell, funded partially through ARP, provides the operational flexibility and redundancy needed to support extensive downstream transmission improvements. Together, these upgrades ensure that WCWSA can produce the volume and quality of water needed to meet long-term regional demands. A major driver behind the ARP-funded improvements is the continued growth anchored by the McLemore Resort development atop Lookout Mountain. Providing reliable potable water, strong fire flow capacity, and stable system pressures at elevations exceeding 2,000 feet requires significant infrastructure investment. WCWSA is constructing a large high-service booster station at the mountain toe, paired with a high-pressure steel transmission main engineered to lift water more than 1,000 vertical feet to the summit. At the top of the mountain, a new 1-MG storage tank and mountain-top booster station will provide reliable service to McLemore and associated developments. Notably, this tank is designed for strategic inter-utility coordination, enabling WCWSA to sell water to Dade County Water & Sewer Authority (DCWSA) for regional distribution. Service expansion on top of Lookout Mountain includes major extensions along Flarity Road and Griff Johnson Road, improving reliability for existing customers while reaching remote residences that have historically lacked access to public water. These projects also include a segment along Highway 157 capable of serving the long-established Camp Adahi (Girl Scouts of America), improving safety, fire protection, and water reliability for the camp and surrounding areas. Due to hydraulic constraints, WCWSA will sell water to DCWSA and repurchase it at Yankee Road, enabling efficient service delivery to the remote Flarity/Griff corridor through a creative, regionally coordinated loop feed. Supporting these expansions is a major upgrade to the valley-floor transmission network, including a 24-inch waterline from the WTP to the Mountain View tank and approximately 73,000 linear feet of new large-diameter transmission main, comprising 30-inch and 16-inch pipelines extending from the WTP toward the Kensington area. These improvements form a resilient backbone that links the upgraded treatment plant to the high-service booster station and mountain-top distribution system. Together, the GEFA- and ARP-funded improvements represent a regional, multi-utility transformation that supports economic development driven by McLemore Resort, extends essential water service to underserved rural communities, and enhances long-term system resiliency for both Walker County and Dade County.
