Billing and account research from public material
Provider-specific research notes are displayed separately from fields that contain only an unavailable-information marker. Read qualifiers in each note and verify current account terms with the provider.
- Rate structure
- New York Public Service Commission tariffed investor-owned water rates; Merrick’s current tariff is subject to a Liberty rate request filed May 29, 2026. Liberty reported that the requested increase for an average Merrick residential customer using 8,000 gallons per month would be $21.20, but the filing is a request rather than a confirmed final tariff.
- Wastewater and sewer calculation
- The reviewed Liberty Merrick water pages do not publish a universal sewer calculation. Where Liberty bills wastewater, the applicable local or tariffed sewer charge is account-specific; customers should use their bill and local service terms rather than assume a winter-average or fixed percentage formula.
- Meter reading
- Liberty is deploying Advanced Metering Infrastructure for Long Island customers. The customer portal and EyeOnWater provide usage graphs, neighborhood comparisons, and leak notifications; the reviewed pages do not state the exact Merrick read/transmission interval or completion percentage of the AMI rollout.
