Cloudy water will be OK

If your tap water appears “cloudy or milky” on Monday, don’t worry — it’s perfectly drinkable, the San Francisco Public Utilities Commission said.

During the next several weeks and intermittently through late February, drinking water in The City, the Peninsula and portions of the South Bay and East Bay may not appear clear when initially poured from the tap, the SFPUC said in a recent statement.
The water will “continue to meet or exceed all state and federal water quality standards” and will clear up if you let it sit for a bit, the agency said.

The cloudiness is due to “tiny air bubbles in the water” that are created as a result of an increased flow of water deliveries from local reservoirs.

The SFPUC plans to fetch water exclusively from the local reservoirs until it has completed routine winter maintenance on the Hetch Hetchy Water System, which filters water derived from a reservoir in Yosemite National Park to 2.5 million Bay Area customers.
After maintenance is completed, the Hetch Hetchy water will again flow into the Bay Area, the agency said.

And for extra assurance, here’s how the SFPUC plans to make sure you’re getting clean water:

“The SFPUC’s Water Quality Division regularly collects and tests water samples from reservoirs and numerous designated sampling points throughout the regional water system to ensure that SFPUC drinking water meets all state and federal requirements for water quality. This level of effort and vigilance is ongoing daily, and will continue during the maintenance period.”
