Sixty-year-old water lines are being replaced at the Y-12 National Security Complex, and 27 of the old lines are identified as high-risk and a Top 10 threat.
Work to replace the pipes began in July 2022 and will continue in April 2023, according to an emailed response to questions provided by spokesperson Kathryn King. The water line replacements are scheduled to be completed in the fall of 2025 at a projected cost of $38.9 million. The old cast iron pipes will be replaced with new ductile iron pipes.
