Liberty Water Wants to Raise Your Nassau Water Bill: What to Know and How to Weigh In
A private water utility is asking the state to approve a double digit rate increase for parts of Nassau County, and public hearings are happening now.
If you own a home served by Liberty Utilities on Long Island, your water bill may be about to change. Liberty filed a rate request with the New York Public Service Commission on May 29, 2026, and the case is still moving through review.
What Liberty Is Asking For
According to the filing, Liberty is seeking revenue increases of about 21.87 percent in Service Area 1 and 30.14 percent in Service Area 2. Service Area 1 covers south shore communities including Lynbrook, East Rockaway, Baldwin, Island Park, Oceanside, and Malverne, while Service Area 2 includes the Merrick District and the Sea Cliff District, reaching into Merrick, Bellmore, Wantagh, Seaford, and Sea Cliff.
In dollar terms, Liberty's own numbers show the requested increase for an average residential customer using 8,000 gallons a month would be $27.77 in the Lynbrook system, $26.89 in Sea Cliff, and $21.20 in Merrick. Some reporting has cited even higher potential increases for certain Nassau customers, up to 37 percent in some areas depending on how the case is ultimately decided.
Liberty has said the additional revenue would fund water main replacements, treatment for PFAS and other emerging contaminants, and lead service line replacements. The company has also proposed expanding its customer assistance program to offer partial bill forgiveness to more eligible households.
Where the Case Stands and How to Be Heard
This is not a done deal. The state Public Service Commission is reviewing the request under Case 26-W-0358, and the commission holds public hearings before issuing a final order. One hearing was set in Albany for November 2, and two additional hearings were added in Merrick and Lynbrook for November 18 after residents pushed for local sessions.
If you want a say, the hearings are the direct channel. Public comment on rate cases goes into the formal record that commissioners weigh before deciding what gets approved, deferred, or scaled back. Past Liberty rate cases on Long Island have ended with phased in increases lower than the initial ask, so the filed numbers are a ceiling, not a guarantee.
What This Means for Your Household Budget
A water bill increase does not show up on your mortgage statement, but it is a real monthly cost that belongs in your housing math, right alongside taxes and insurance. If you are budgeting for a purchase in a Liberty service area, or just trying to see where your money goes each month, run the numbers with our what can I afford tool, which lets you edit insurance and other carrying costs rather than relying on a single rough estimate.
If you already own in one of these service areas, this is a good moment to check your most recent water bill against your system (Lynbrook, Sea Cliff, or Merrick) so you know your actual baseline before any new rate takes effect. Homeowners selling in the next year should also expect buyers and their agents to ask about recurring utility costs, so documenting your current bill now saves a scramble later.
