FULTON COUNTY, Georgia — With the successful completion of the Big Creek Water Reclamation Facility (WRF) Plant Expansion, Fulton County has achieved a historic milestone in its goal of safeguarding the environment and supporting a thriving, healthy community.
Delivered via progressive design-build as a joint venture between BC and Archer Western, the $350 million project is Georgia’s largest progressive design-build project and the county’s largest capital project. Using state-of-the-art technology, the new Membrane Bioreactor (MBR) facility increases capacity from 24 mgd to 32 mgd, significantly reducing nitrogen and phosphorus to the Chattahoochee River by more than 250,000 pounds annually.

“This project has been a remarkable journey for all involved. The new facility enhances Fulton County’s treatment capacity but also demonstrates the team’s commitment to innovative and sustainable solutions for water reclamation.”
Brown and Caldwell Project Manager Kelly Comstock
The project is the third WRF BC has converted to MBR technology for Fulton County. It also features innovative attributes such as a gravity configuration that will save an estimated $13 million in power over 30 years and an advanced Side-Stream Enhanced Biological Phosphorus Removal (S2EBPR) process.
Over the past seven years, 286 BC staff from over 30 offices contributed more than 130,000 manhours to this project. In October, the County and community celebrated the Big Creek Water Reclamation Facility WRF Plant Expansion with a ribbon-cutting ceremony.
The project is expected to reach final closeout following the demolition of the old plant facilities, slated for completion late this spring.
