As Austin moves toward six full days on a citywide boil-water notice, Austin Water announced Sunday afternoon that it would begin sampling certain areas of its water supply to make sure water is safe to drink.

Contaminants have not been discovered in the water, but the notice is still in effect and could be for the next coming days as the city sends samples to a lab for testing. The boil-water notice went into effect as a result of power loss and reduction of water pressure at the Ullrich Water Plant.

On the same day, Austin Water announced that two of its zones had regained low-pressure running water.

Both the South and Northwest A zones have climbed from Red (Water Outage) to Orange (Low Pressure), bringing the tally up to four areas with some semblance of running water. Five of the nine water utility regions are still out of water.

The department also announced that storage in reservoirs had jumped to 72 million gallons, with a minimum of 100 million gallons needed to resume normal operations.
