Riviera Utilities executed a contract with Goodwyn, Mills and Cawood Inc. (GMC) to design a wastewater treatment plant expansion utilizing Royal HaskoningDHV’s Nereda granular activated sludge technology as the basis of design. The new advanced process will be designed for the Wolf Creek Wastewater Treatment Facility in Foley, Alabama in the Unites States of America. Use of granular activated sludge for biological treatment will be the first installation of such technology in the United States.

Nereda replaces aeration oxidation ditch process

The new design of the Wolf Creek Wastewater Treatment Facility will consist of a three-basin Nereda biological system will replace the current extended aeration oxidation ditch process that currently serves approximately 4,720 residential and commercial customers and will have an avarage capacity of 13,250 m3/day (3.5 million gallons/day) and 37,850 m3/day (10 million gallons/day) at peak flow. This first-of-its-kind project is the result of successful collaboration among GMC, Riviera Utilities, Aqua-Aerobic Systems Inc., of Loves Park, Ill., the exclusive supplier of the Nereda technology in the United States of America and Cahaba Water Solutions of Pelham, Alabama, the local Aqua-Aerobic representative.

Game changing advancement

"Improving and protecting water quality for current residents and future generations utilizing the Alabama Outstanding Waters of Wolf Bay is our number one priority," Lee Kibler, Operations Superintendent Water/Wastewater for Riviera Utilities said. "We are delighted to be involved in the game changing advancement of the reclamation process of wastewater in the United States through utilization of the Nereda Aerobic Granular Sludge Process at the Wolf Creek Treatment Facility."

"GMC is honored to work alongside Lee Kibler and his staff at Riviera Utilities on the Wolf Creek Wastewater Facility," Bobby McClure, GMC Vice President of Water Resources and Treatment said. "We are equally excited to be teaming with the Aqua-Aerobics and Nereda utilizing granular activated sludge technology for the first design in North America. We believe this project will be a catalyst for all parties to improve the options and efficiency in which sequencing batch reactors are designed and operated. The Nereda technology and the alliance with Aqua Aerobics is no doubt a new tool in our portfolio that we plan on using to assist our clients in the development of efficient and cost competitive processes."
