Welcome to OWASA


November 19 is International Toilet Day!

When you flush the toilet, where does it all go? Last year, OWASA's wastewater system treated 2.8 billion gallons of wastewater, an average of 7.8 million gallons per day. OWASA's extensive wastewater treatment system mimics nature's processes and uses technology and compounds to accelerate it.

Jones Ferry Rd water main break repaired 

On the morning of November 5, 2018, a water main break occurred on Jones Ferry Rd which affected water storage levels and water pressure in the system. Customers in OWASA's service area were asked to conserve water over a 24-hour period, and boil water before consuming it for a 30-hour period. Storage levels are back-to-normal and customers are using water as usual. We are investigating the cause of the break and will share information as it becomes available. We are very sorry for the inconvenience the event caused. We understand the community seeks to know more. View answers to your frequently asked questions, a timeline, and detailed presentation about what happened during the event on the dedicated Jones Ferry Rd water main break information page.
