Rates Information

Long Island American Water’s rates are based on the true cost of providing water service to our customers.

Rates can vary based on the cost of providing service in each of the communities we serve. Before it reaches your home or business, water is treated through an involved process. Water begins its journey at the source (river, stream, reservoir, aquifer) and travels through our highly sophisticated plants, into underground pipes, to its final destination, your tap. Along the way, our team of professionals (certified operators, scientists and engineers) are using the latest technology as to oversee and monitor the process. We test the water quality using leading edge methods we pioneered. We understand the value of clean, high-quality water on tap 24 hours a day, and are committed to delivering it reliably.

Reliable high-quality water service improves our lives and communities by:
    • Protecting public health
    • Providing fire protection
    • Creating opportunities for economic growth

In New York, rates must be approved by the 

 New York State Public Service Commission
