NYC Commercial Water Rates: Adopted FY2027 Water and Sewer Bill Guide

What the Water Board adopted

Source-reported facts: the New York City Water Board adopted a 6 percent FY2027 rate increase on June 10, 2026. The new schedule took effect July 1, 2026 for the city water and sewer system.

The current Water Board schedule lists metered water at $5.35 per 100 cubic feet, or CCF. Sewer remains 159 percent of the water charge, equal to $8.51 per CCF, for a combined $13.86 per CCF before account-specific adjustments.

Who is affected

Commercial and multifamily buildings billed on standard NYC metered water and sewer volume are included in the FY2027 schedule. High-use hotels, restaurants, mixed-use properties, offices, healthcare facilities, laundries, campuses, and apartment buildings will see the largest dollar exposure when billed CCF stays flat.

The 6 percent figure is a rate change, not a forecast of each building’s total bill. Actual results still depend on billed volume, sewer applicability, minimum charges, credits, estimated reads, account adjustments, and operating changes during the billing period.

Why the sewer multiplier matters

Every $5.35 of standard metered water at one CCF carries another $8.51 of sewer when the 159 percent linkage applies. Commercial budgeting should therefore use the $13.86 combined variable rate rather than treating the water rate as the full usage-linked exposure.

The adopted notice also retains a $0.49 minimum daily charge. Low-volume or irregular-use accounts should inspect that minimum and any other non-volume line before treating the entire bill as reducible through lower consumption.

What the adopted increase means at 300 CCF

Smart Valve analysis: the prior FY2026 schedule combined $5.05 per CCF of water with $8.02 of sewer, or $13.07 per CCF. FY2027 is $13.86, a rounded difference of $0.79 per CCF.

At an unchanged 300 CCF per month, that difference represents about $237.00 more per month, or $2,844.00 over 12 equal months, in combined variable water-and-sewer exposure. This directional comparison excludes minimum charges, credits, adjustments, and any change in billed usage.

Water, sewer, wastewater, and stormwater implications

For the modeled standard account, water is the metered CCF line and sewer is the larger linked charge. That sewer line supports wastewater-system costs, so reducing billed volume can matter twice when the 159 percent relationship applies.

The adopted schedule used here does not establish a separate usage-reducible stormwater line for a commercial property. If a bill or site agreement shows stormwater, frontage, meter, fire-service, or other fixed fees, keep them separate unless an official rule expressly ties them to metered consumption.

What a 20 percent usage reduction could mean

Directional estimate: a 20 percent reduction from 300 CCF equals 60 CCF. At the adopted $13.86 combined water-and-sewer rate, those 60 CCF represent $831.60 per month, or $9,979.20 across 12 equal months, in usage-linked exposure.

This is not a savings guarantee. It assumes the sewer multiplier applies to the reduced billed volume and excludes minimum or fixed charges, credits, estimated-read corrections, operating changes, taxes, account adjustments, site conditions, and installation feasibility.

What to check first on the bill

Record billed CCF, water charge, sewer charge, service dates, actual or estimated read status, minimum charges, credits, adjustments, and any separate non-volume fees. Recalculate the effective per-CCF amount from the bill rather than applying 6 percent to a total that may contain fixed items.

Then compare the same operating month year over year. Flag occupancy shifts, tenant turnover, restaurant or laundry demand, cooling towers, irrigation, meter-access problems, continuous flow, and suspected leaks before attributing the full change to rates.

Where Smart Valve fits

Smart Valve belongs in the broader bill-reduction plan when a meaningful portion of the account is tied to controllable metered volume and the site conditions are suitable. It cannot reduce minimum charges, fixed fees, inactive or unrelated surcharges, or any stormwater line that is not linked to usage.

The practical next step is a 12-month bill assessment that separates the $13.86 usage-linked baseline from non-volume charges. A site-specific model can then test whether lower billed CCF could offset part of the adopted rate pressure without presenting the result as guaranteed savings.
