PURPOSE:
The City of Greensboro Water Resources Department is requesting to enter into a professional services contract with HDR Engineering, Inc. of the Carolinas to assess the current condition of the City's Air Harbor Reservoir. The evaluation will identify structural options for rehabilitation and determine from a process and a water quality standpoint if the current reservoir should be modified or replaced for conveying raw water to the treatment plant.
BACKGROUND:
The Lake Brandt Pumping Station pumps water from Lake Brandt to the Air Harbor Reservoir, which is used for flow and equalization storage. The water drains from the reservoir by gravity to the Mitchell WTP for treatment where it is subsequently pumped to supply drinking water to the City of Greensboro.

The professional services of HDR Engineering, Inc. of the Carolinas will be utilized to investigate and inspect the condition of the Air Harbor Reservoir. The proposal includes a technical evaluation of the current structural condition of the reservoir, potential required repair work and overall useful life. Additional investigation includes the evaluation of the reservoir and its overall role in water treatment performance in terms of turbidity, total organic carbon and dissolved metal reduction to determine the reservoirs benefit for pretreatment ...
