Our water is safe to drink.
Our water professionals test and monitor drinking water quality 24 hours a day, every day of the year. We produce approximately 75 million gallons of safe drinking water daily for nearly 500,000 people.
Hundreds of water quality tests are performed each day at the Collins Park Water Treatment Plant by certified chemists who are on duty around the clock to ensure our drinking water meets or exceeds all water quality standards. Water samples for microcystin are collected bi-weekly and analyzed on Tuesday. When lake conditions warrant, testing will be increased.
