AUSTIN — Multiple schools in Austin ISD dealt with boiler issues this week, with students at Bowie High School being left temporarily without their normal supply of central heating.

According to the school district, a total of 18 portable heaters were delivered to the school after a water line break feeding into its boiler system. AISD said maintenance crews were notified about the issue around 6 a.m. and repairs were finished by 12:30 p.m. AISD maintenance crews have been adding water to the loop and restarted the boilers just before 2 p.m.

School leaders said the water line issue was the result of an expansion joint that failed, stating that though broken pipes have occurred in the past, Wednesday's issue was not a direct issue with the boiler.

Casis and Lee elementary schools also experienced water line breaks on Monday. The issue at Lee was fixed in the early morning as the boiler was reset. At Casis, a part needed to be replaced. That issue was completed in the early afternoon.

AISD said the school did not need to deliver portable heaters at the elementary schools. These issues were the "result of typical equipment malfunction and part failure and were addressed quickly to resolve the issue."

Bowie's current enrollment is 2,463 students, while Casis and Lee have 745 and 432 students respectively.

"Austin ISD will continue to be proactive in our approach to maintenance when possible and respond quickly to matters related to equipment and parts failure," school leaders said.
