Mars Hill Church Rd. to Pine Mountain Rd. 36-inch Water Main Replacement Project
The Mars Hill Church Rd to Pine Mountain Rd 36-inch Water Main Replacement project involves replacing an aged, undersized section of a water line in northwest Cobb County. The existing 30- and 36-inch prestressed concrete cylinder pipe will be replaced with a 36-inch ductile iron pipe. This new water line will reduce the potential for pipeline failures and increase water supply capacity. In most cases, the project will involve removing the existing pipe from the ground and installing the new pipe in its place.
Project: DOT - Old Hwy 41 & Stilesboro Road Water Main Replacement Project
This project includes three areas of work: approximately 4,800 feet of new 16-inch ductile iron pipe (DIP) water main will be installed in central Cobb County, along Church Street Extension, Loudermilk Road, and Marble Mill Road. To maintain high water quality and adequate fire protection, a 7,800-foot section of 12-inch DIP will be installed to transfer service connections and fire hydrants off the existing 30-inch transmission main on Stilesboro Road and through the National Park Service area. Lastly, the project will connect CCMWA's existing pipeline to Cobb County Water System's existing pipeline along Cobb Parkway to maintain adequate water pressure within the area. This project is necessary due to a Cobb County Department of Transportation road relocating project at the request of the NPS, which includes two roundabouts and a pedestrian crossing. By adding these pipeline sections, CCMWA supply to this area will shift away from the NPS areas.

Factory Shoals 30-inch & Six Flags 24-inch Water Main Replacement Project
The Factory Shoals and Six Flags water main replaces an aging pipe system of 1980s 20-inch diameter concrete pipe, reaching the end of its useful life. The new 24-30-inch diameter ductile iron pipe will increase reliability and mitigate risks of catastrophic failures by replacing the aging infrastructure with more reliable and longer life span materials. This new water main will provide adequate water supply to Cobb County residents and neighboring customers for decades. The water main will be installed in the travel lanes of Factory Shoals Road, Riverside Parkway, and Cityview Drive to minimize conflicts with other buried utilities and impacts to private property.
Maner Road 36-inch Water Main Replacement Project
The Maner Road 36” Water Main Replacement project involves the replacement of approximately 5,000 LF of 36-inch ductile iron pipe (DIP) with 36-inch DIP and 30-inch fiberglass reinforced polymer (FRP) pipe. This section of water main has experienced several corrosion related failures in recent years. The decision to replace the DIP with corrosion resistant FRP should stop future failures and extend the life of the transmission water main in this area.
James E. Quarles Plant 1 Replacement Project
Completed in 2021, the award-winning James E. Quarles Plant I Replacement Project supplies reliable, sustainable, high-quality potable water to over one million for generations to come. Provisions to double the plant capacity are built into the facility ensuring today's infrastructure will sustain water production needs well into the future.
The existing Quarles Plant 1 was constructed in the 1950s and had reached the end of its useful life. The replacement Quarles Plant 1 needed to be constructed within the same footprint of the existing facility while keeping the original facility operational to treat and deliver safe drinking water. The new 33 million gallons per day (MGD) Quarles Plant 1 includes treatment processes and structures with improved redundancy, reliability, and flexibility. The $72-million dollar James E. Quarles Plant 1 Replacement Project for CCMWA came in under budget by over $1 million dollars.
