A break in Yountville’s recycled-water main serving the Vintner’s Golf Club and various vineyard ponds east and west of the Napa River has led to an emergency $1 million repair project, approved by the Town Council last week. The main in question is a 6-inch PVC pipe, first installed in 1977, that runs across the floor of the Napa Valley from the Yountville wastewater treatment plant west of Highway 29. It reaches as far as the Clos du Val Winery pond past the Silverado Trail, to the east, Yountville’s public works director John Ferons said at the council meeting. As such, the water line also runs below the Napa River, which is where the leak was discovered about two weeks ago. Yountville town staff discovered the leak at noon Feb. 15 because a low-flow alarm went off, and workers shut off the pumps to investigate the pipes, according to a staff report.
