The Water Authority of Western Nassau County has moved to it's newly constructed headquarters building at 1580 Union Turnpike, New Hyde Park.

We are very excited to be moving into a new facility that will help us provide better customer service.

All of our telephone numbers remain the same, so please call (516) 327-4100 to speak with a customer service representative.

We have published our Annual Water Quality Report for 2012. You can view all of our Water Quality Reports on this page.
