- 50 percent increase in overall water treatment capacity
- New granular activated carbon filters will address polyfluoroalkyl substances (PFAS) and pharmaceuticals
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.
The work consisted of rehabilitating 18 filters where no more than 3 filters were taken down at a time to ensure seamless MOPO. The scope consisted of draining the filters, removing the media, pouring a new concrete slab, and installing the Orthos system.
Our team ensured there was no disruption of service to Metro Water Service’s customers and finished the project five months ahead of schedule. Because of the team’s hard work, the filters have longer run times, and the plant treatment capacity increased from 90 million gallons per day (MGD) to 112 MGD.
