The Terris Tatum Tennessee River Intake Facility is a raw water intake for the Quarry Water Treatment Facility located in Madison Alabama. Krebs worked with Madison Utilities to obtain permits from the US Environmental Protection Agency, US Fish and Wildlife Service, US Army Corps of Engineers, Tennessee Valley Authority, and the Alabama Department of Environmental Management to construct the raw water intake along the shoreline of the Tennessee River and located in the Wheeler Wildlife Refuge. The intake is a permitted 29 MGD withdrawal from the Tennessee River. The intake pipeline is a 60-inch diameter pipeline which extends over 400 feet into the main channel of the Tennessee River. The Intake pipeline is equipped with two 48-inch diameter passive intake screens with an air burst cleaning system. The raw water pumping station has three vertical turbine pumps with space to add two additional pumps. The raw water pumping station currently has a firm pumping capacity of 12 MGD. The project included an electrical building with a 1.5 megawatt generator.
