DeKalb County recently signed its first major contract toward a $1.34 billion overhaul of its water and sewer system.

The county inked a $7.7 million contract with Desmear Systems of Tucker, which will grade and prepare the land around the Snapfinger wastewater treatment facility for a major expansion.

The firm is expected to begin clearing the site and excavating rock on June 1 and will later build a retaining wall to help with future construction.

The county plans to spend about $250 million to rebuild, upgrade and expand the Snapfinger facility, making it the single largest project in the system upgrade.

The county expects to begin about $400 million of improvements to the system this year. All of the projects are being paid using bond funds.
