The Johns Creek Environmental Campus (JCEC) is located in north Fulton County, Georgia and has been operating for over a year. JCEC employs leading edge membrane bioreactor (MBR) technology to treat wastewater to levels suitable for discharge into approved trout waters and the reuse water distribution system in north Fulton County, Georgia. This show-case plant is a completely enclosed facility that has architectural elements giving it the appearance of a historic mill complex located on the Chattahoochee River. The site has become a shared use park and nature center with the City of Roswell and includes a cascading reuse water stream and pond with an interpretive nature trail including a reproduction of a covered bridge. The new facility uses low impact design elements that incorporate sophisticated noise and odor abatement features / technologies to limit the noise and odor to background levels within 25 feet of the buildings. In addition, an educational lecture hall, classroom and teaching lab were constructed to educate local school children about wastewater treatment and the impact of water quality on the local environment and the Chattahoochee River. The JCEC is permitted for 15-mgd and is the largest MBR operating in North America until King County, Washington’s Brightwater WRF starts up. A design build approach was utilized to design, construct, and startup this facility in < 36-months to allow a 4-month operational period to demonstrate to Fulton County that the facility’s O&M costs were in line with projections. This paper will detail the design process for this low-impact and extremely compact facility, which will include information on the architectural elements, process selection and sizing, online equalization, noise and odor abatement, and community consensus building. This paper will also discuss operational data and cost information from the first year of operation will be presented.
