Customers of New York American Water who were already fuming over skyrocketing bills may be getting an additional surcharge.

Due to a recent change in state law, the utility stands to lose millions of dollars in state income taxes. It is asking the Public Service Commission to approve a new surcharge to cover those lost costs.

Many customers say they shouldn't be the ones to pay for the company's loss.

“These are pigs at the trough,” said David Denenberg, of Merrick.

Denenberg said his bill almost doubled since last year to $250 a month. As co-director of a watchdog group known as Long Island Clean Air, Water and Soil, Denenberg said the proposed surcharge adds insult to injury.

“It's outrageous they're even asking for this with what they're doing to their ratepayers,” he said. 

Denenberg's group and many other residents said they are going to step up their fight for a public takeover of their water supply.

New York American Water is currently being investigated by the state and Nassau County for its billing practices.

The utility issued a statement to News 12 that did not address the new surcharge:

“New York American Water always works to limit the negative impact of a regulatory or legislative change on our customers. The legislative change that occurred in New York increased the company's state tax burden, but New York American Water and the New York State Department of Public Service will look to offset the new costs with the recent reduction in their federal income tax rates. Our goal is to minimize the adverse impact on customers as a result of the tax change.”
