Building a new water treatment plant in Oak Ridge or renovating the current one could cost between $43.1 million and $46.9 million, according to an evaluation prepared for the city by an engineering company.
Three alternatives for renovating the existing water plant or building a new one were presented to the Oak Ridge City Council in October in an evaluation by Jacobs Engineering Group. The three options have different impacts on the raw water intake on the Clinch River in south Oak Ridge, an intermediate pump station at the Y-12 National Security Complex between the raw water intake and the existing water treatment plant, and the current 70-year-old plant, which is on Pine Ridge above Y-12.
The first alternative, which could cost $46.5 million, would rehabilitate the existing plant. It would continue to use the raw water intake, the intermediate pump station, and the water plant. It would include work at those three sites, as well as to the two underground lines that feed the water plant.
The rehabilitation would require mechanical and process equipment upgrades, pipeline replacement, electrical improvements, and slope stabilization.
The Jacobs evaluation said the building and basins at the existing plant are in good condition, and the facility works well at 8-12 million gallons per day. It has the two underground lines coming in and three going out, and two storage reservoirs on Pine Ridge, one of three million gallons and the other of four million gallons. [Read more…]
