Two Thompson Pump Vacuum-Assisted Dry Prime Trash Pumps are installed on the earthen dam in order to lower the water level of Bear Creek Lake.Click here to enlarge imageFlooding and heavy rains caused by Hurricane Floyd in 1999 eroded the emergency spillway, damaged earthen dams, and clogged underground pipes that were essential to the draining process of the watershed. Since then, federal money issues, litigation disputes between the county government and residents along Bear Lake, and heavy rains have diffused any efforts to repair the watershed system. Last year, heavy rains again pelted Wayne County, causing the lake's level to rise dramatically and threaten lakefront property. County officials needed to act quickly, to avoid further deterioration of the watershed.
Roland Gray, chairman of Wayne County Drainage District #1, was in charge of the watershed pumping operations. His actions were under close scrutiny from the Environmental Protection Agency, the Wayne County Soil Conservation Group and the North Carolina Forestry Service, looking for options to protect the watershed, Gray contacted the local representative at Thompson Pump's Goldsboro, NC, branch.
After visiting Bear Creek Lake, the Thompson representative proposed the installation of a 12 inch vacuum-assisted Dry Prime Trash Pump and 60 feet of suction hose with a strainer mounted to a floatation device to prevent the suction strainer from being buried in the ground. The vacuum-assisted pump was selected due to its high amount of flow and air handling capability.
The discharge side was comprised of 100 feet of Thompson galvanized pipe and was directed onto the other side of the dam where the watershed was operating properly. Company crews were able to install the entire system within hours of the initial contact from Gray. The county already owned an 18'' pump system, which was going to be installed by the Forestry Service, alongside the Thompson Pump system, to increase the reduction of Bear Creek Lake.
