Who will be affected? What locations?

The City’s overall water system has been divided into three (3) flushing areas, therefore over a three (3) year period the whole system will have been flushed and the cycle will start over again. This year, we are conducting hydrant flushing in Zone 2, areas on the north side of Napa up to Sierra Avenue and the near west side of town, and Zones 4 and 5, areas above the Silverado Country Club.  Areas not included in this year’s program will be flushed in the winter of 2020-21 or 2021-22.  View map of the Full City Flushing Area (PDF).
