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.  

The Q1 replacement project will occur in three phases.  The first phase will demolish half of the existing Q1 building while ensuring the remaining half of the Q1 remains fully functional and able to provide high quality drinking water.  The second phase is to construct the new Q1 treatment facility.  The final phase consists of demolishing the remaining half of the Q1 building.  

To date, the first phase has been completed.  As we enter the second phase, we will begin construction with a primary emphasis on concrete work over the next year.  

The new Q1 building is scheduled to be complete by April of 2020 with an overall project completion of September 2020.
