PHOENIX - A suite wastewater pipe burst at Phoenix Raceway over the weekend, which prompted immediate repairs, patron medical transport, and sanitization.

Just before 6 p.m. on Oct. 17, several fans at the Phoenix Raceway were caught in the splash zone after a wastewater pipe from a suite.

The raceway "immediately responded to ensure the safety and well-being of the fans involved."

Following the incident, the pipe was repaired, and the area was sanitized with the help from the Maricopa County Health Department.

What they're saying:

The Communications Department Officer with Maricopa County released the following statement on Oct. 20, following the water pipe burst:

"The Phoenix International Raceway staff notified Maricopa County about a burst sewer pipe. Maricopa County Environmental Services provided input on the efforts the raceway Hazmat team had already taken to rectify the situation. The burst pipe was repaired, and the affected patrons were promptly transported to a medical facility. The areas affected by the burst pipe were cordoned off and sanitized, as verified by Maricopa County staff on Sunday morning."
