Repairs to water plant continue in Lago Vista; conservation urged, boil water notice in place

LAGO VISTA, Texas - Repairs are continuing at a water treatment plant in Lago Vista after an emergency outage over the weekend, and a boil water notice remains in effect for part of the city.

A boil water notice currently applies to the area south of Dawn Drive, near Lohman Ford Road.

What we know:

The outage occurred on Nov. 30 and impacted residents south of Dawn Drive, including Drapers Cove. Although water service was restored within a couple of hours as pressure stabilized, the city is urging residents to conserve water until permanent repairs are complete.

The outage was caused by an operational issue at Water Treatment Plant 3, which remains offline. Contractors began excavating at the site early Monday morning to locate the damaged section of the water line and prepare for permanent repairs.

As of 6:20 p.m. Monday, the city confirmed that contractors have begun assembling the new connection for the water line. Repairs are expected to continue into Monday evening or into Tuesday morning due to the complex nature of the work.

Boil water notice

Why you should care:

The city emphasized that the boil notice was issued "out of an abundance of caution" following a temporary drop in system pressure.

Full city statement:

"The City of Lago Vista has issued a Boil Water Notice out of abundance of caution following a temporary loss of pressure within the municipal water distribution system and, per state regulations, a public notice is required at this time. Until further notice, all customers should boil their water prior to consumption, including for drinking, cooking, making ice, brushing teeth, or washing food. To ensure safety, bring water to a vigorous boil for at least two minutes before use. We will lift this notice as soon as test results confirm the water is safe to drink. Updates will be provided through official City communication channels."

Public Works crews quickly restored pressure after the outage, but state law requires testing before the notice can be lifted. City staff collected water samples Monday, which were sent to a state-approved lab for analysis.

What you can do:

Residents in the affected area must boil all water used for:

• Drinking
• Cooking
• Making ice
• Brushing teeth
• Washing food

Water should be brought to a vigorous boil for at least two minutes before use. The city will lift the notice once lab results confirm the water is safe.

Impact on local schools

Dig deeper:

Lago Vista ISD canceled classes Monday at Lago Vista High School because the campus did not have water. District staff worked remotely while all other campuses and departments operated normally.

The district now says it has received the all-clear from the city, and Lago Vista High School will reopen Tuesday.
