Garney Construction Companies, Inc. is scheduled to begin preliminary work on the Southwest Regional sewage force main, a 36 inch diameter pipe, across the Stones River near Medical Center Parkway.

As part of preparations for construction work over the river to Old Fort Golf Course, Garney will be constructing signs and gates along Stones River near Sportsman's Club. The signs will warn the public about construction dangers and abnormally low water levels above the dam in this portion of the Greenway.

Work will require siphoning to lower water levels and rock blasting to bore holes in the affected area. Residents need to be advised that the water level above the dam will be too shallow for diving and swimming. In addition to fencing gates restricting access, signs will warn the public to "Danger: Shallow Water Due to Construction/No Diving" and "Danger: Construction Area/Keep Out."

Garney estimates the work to be completed by mid-September. The Southwest Regional sewage force main river crossing project is part of an $8.3 million dollar contract awarded to Garney in 2013 that will link the Southwest Regional Pumping Station. The station is being constructed along Old Fort Parkway to a new screening facility (Headworks) located at the Sinking Creek Wastewater Treatment Plant on Blanton Drive.
