“Like we do every year, when we’re notified about water waste, we’ll follow up with the property owner so they’re aware of any issues,” Tejral said. “If there are repeat violators who need additional and in-person assistance, one of Denver Water’s field service technicians will respond.”

Watering restrictions continue through Oct. 1.
