Camp Shelby Sewer Rehabilitation - Sewer Network Phase
Camp Shelby Joint Forces Training Center · near Hattiesburg, Mississippi · Forrest County
Large-diamter sewer main lies ready for connection.
Workers dig up the old system, rehabilitating manholes along the way.
After lying beneath the earth for more than 60 years, enduring countless hard freezes and hot summer days, the sanitary sewer system at Camp Shelby was failing fast by 2005. Inflow and infiltration into the broken pipes and manholes was causing the system's flow rate to spike by a factor of 50 during heavy rains, and the also-inadequate wastewater treatment plant was overwhelmed by these events. The Mississippi Military Department turned to WGK, Inc., for an aggressive rehabilitation program that would see tens of thousands of linear feet of sewer piping rejuvenated, manholes strengthened and unused networks disconnected. The improvements brought average daily flow down to a consistent 250,000 gallons per day and allowed planning to begin for a new wastewater treatment facility.
