Collinsville Issues Boil Water Notice for Customers North of 12374 U.S. 377

Collinsville water customers north of 12374 U.S. Highway 377 are being told to boil their tap water, under a boil water notice the City of Collinsville issued on July 13, 2026. The city put out the order after a loss of pressure in part of the community public water system, according to the notice. Only that portion of the system is covered.

The boundary is specific. According to the notice, the order covers customers north of that point on U.S. 377 and no one else served by the system. A customer south of that address is outside the order as Collinsville has written it.

The order also appears in a second official location. Collinsville posted it on the city's homepage as a public notice, and that version carries the same limit, customers north of the highway address. The notice names a loss of system pressure as the reason the order went out.

Boil orders at Texas community public water systems run on procedures published by the Texas Commission on Environmental Quality, and Collinsville's notice describes its system in those terms. Those procedures require a system to notify its customers within 24 hours. They also dictate the wording; the notice language is mandatory under the state's rules.

The procedures cover the end of an order as well. When boiling is no longer necessary, the system must issue a rescind notice, a separate announcement that comes later in the process.

Residents who want these alerts delivered to them directly have a sign-up option. Collinsville's resident-services page points to the Grayson County CodeRED system, which the page says can send targeted emergency notifications. Boil-water notices are named there as one type of message the system handles. The same page says residents can enroll for alerts about service interruptions from the city, and county-level alerts are available as well.

Nearby Gainesville handled a similar order last year, and that one was also partial. Gainesville issued its boil water notice on Jan. 13, 2025, after a water-main break dropped system pressure below 20 pounds per square inch, according to Gainesville city records. The order there did not last long. City records show Gainesville rescinded it two days later, once corrective actions and laboratory results established that boiling was no longer required.

That timeline belongs to a different city and a different water system, and it says nothing about when the Collinsville order will end. For now, the notice posted on Collinsville's homepage stands for customers north of 12374 U.S. Highway 377.
