Project Overview

Omohundro and KR Harrington have been providing clean drinking water to the Nashville area since 1889 and 1978, respectively. Currently, Metro Water Services provides clean and safe drinking water to 191,000 citizens in Davidson County and the surrounding areas through over 3,000 miles of water mains. Each water treatment plant has a capacity of 90 million gallons per day, and the new system will increase the volume of water output by up to 50 percent. Once complete, the project will achieve Metro’s rigorous water quality standards and continue to provide safe drinking water to Nashville-area residents and visitors for another 100 years.

Because Omohundro Water Treatment Plant is listed on the National Register of Historic Places, the larger project scope includes historic preservation of some of the plant’s unique aesthetic features like brick arches, stained wood plank ceilings and green and white checkerboard terrazzo flooring. Sundt is currently focused on the first phase of the project—the KR Harrington campus where Sundt is refurbishing the 18 filters, resurfacing all concrete walls and demolishing the existing underdrain system, which will be replaced with a new Orthos underdrain system.
