Quarles Plant 1 Project

Constructed in 1953, our James E. Quarles Water Treatment Plant, located at 4402 Lower Roswell Road in Marietta, has helped provide our county and surrounding counties access to nearly 86 million gallons of water per day. The James E. Quarles Treatment campus is the site of two water treatment plants: Quarles Plant 1 (constructed in 1953) and Quarles Plant 2 (constructed in 1979).

In 2017, the decision was made to replace Quarles Plant 1 (Q1) as it neared the end of its useful life. The Quarles Plant 1 project will demolish all the nearly 60-year-old structures associated with Quarles Plant 1 and rebuild a new water treatment facility in its place. The Q1 plant will have a treatment capacity of 33 million gallons per day and will ensure the ongoing treatment of operations.

To date, the first phase has been completed and demolition of the remaining half of old Q1 has commenced. Overall, concrete placement on the new Q1 buildings is approximately 96% complete. Major equipment such as pumps, motors, and electrical gears have started to arrive and are being installed.

The new Q1 facility is scheduled to be operational in September 2020 with an overall project completion in November 2020.
