Annual Water Quality Report

We have published our Annual Water Quality Report for 2020. You can view all of our Water Quality Reports on this page.

Outside Water Use Restrictions

The Water Authority reminds customers that all residents of Nassau County are prohibited from outside water usage year-round between the hours of 10 a.m. and 4 p.m.

In addition, the following restrictions apply:

  • Customers with Odd-Numbered addresses may only water on Odd-Numbered Days
  • Customers with Even-Numbered addresses or premises without a numbered address, may only water on Even-Numbered Days.
In addition, the summer weather has resulted in extraordinary demand for water service.  In order to avoid more serious problems that would hinder our ability to provide water for fire protection and other essential services, we are calling on our customers to voluntarily reduce outdoor water usage such as lawn watering and car washing or similar non-essential water usage.

Should you have any questions, please contact our customer service department  at (516) 327-4100 Monday through Friday between the hours of 8:00 AM to 5:00 PM.
