Gwinnett’s Board of Commissioners voted Tuesday to award a hefty contract for the renovation of a wastewater treatment facility.

The county will pay Alberici Constructors nearly $132 million to continue “the modernization” of the Crooked Creek Water Reclamation Facility in Peachtree Corners, which processes 16 million gallons of wastewater each day. The project will include “enhancements to the electrical system, efficiencies in chemical and power usage and increased reliability through the replacement of older systems and equipment,” officials said.

County officials said the renovation will also include “improved protection of the environment” and enhanced odor and noise control.

According to county documents, the contract will be broken down over five years. Just over $13 million has been budgeted in 2017, with nearly $34 million slated for each of the following three years. Just shy of $20 million would be paid in 2021.

Crooked Creek has been in operation since 1972 and has been upgraded and expanded several times since. In 2016, new operational control centers and maintenance facilities were built.

Crooked Creek has the lowest capacity of Gwinnett’s three wastewater treatment facilities. The Yellow River facility near Lilburn is able to process 22 millions gallons of water each day, and the F. Wayne Hill facility near Buford has a capacity of 60 million gallons.
