St. Helena’s Water Pipe-Cleaning Program Began Its Citywide Phase in Late October

ST. HELENA, Napa County — St. Helena’s official water updates page lists a citywide pipe-cleaning program scheduled to begin Monday, October 26, 2026. The city has also published separate information about zero-discharge flushing and concerns regarding discolored tap water.

The public updates document a longer-running problem affecting customer confidence in the system. The city has discussed reports of water discoloration, taste and odor over multiple months. A notice that work is starting does not prove every pipe has been cleaned or that every individual customer issue is resolved.

What customers should monitor

Read the dated updates and city FAQ for information about maintenance, water appearance and any recommended precautions. The city provides advice on reporting problems and describes why reports from different locations can help identify where discoloration is occurring.

How to report ongoing concerns

St. Helena directs residents to the Grapevine reporting system or 707-968-2658. When reporting, record the location, date, approximate duration and appearance of the water. If you need guidance about drinking-water safety, check the city’s current advisory and consult relevant public-health guidance rather than making assumptions from its color alone.
