Hayward Commercial Water and Sewer Rates: October 2026 Non-Residential Bill Checks

What changed in Hayward

Source-reported facts: Hayward says City Council adopted water rates effective October 1, 2025 and October 1, 2026. For non-residential water, the October 2026 schedule lists $9.22 per CCF for 1-110 CCF and $10.82 per CCF above 110 CCF.

Hayward also lists adopted sewer rates effective July 1, 2026 through July 1, 2029. Non-residential sewer charges are calculated per CCF of metered water use based on the strength of discharged wastewater, with separate tables for accounts with and without separate irrigation meters.

Who may be affected

The commercial exposure is broad: restaurants, commercial laundries, food manufacturers, bakeries, beverage bottling, meat products, industrial laundries, fabricated metal users, multifamily assets, office buildings, healthcare facilities, and irrigated sites can land in different sewer categories.

For October 2026 water service, a 2-inch residential or non-residential bi-monthly fixed fee is $286.35, a 3-inch meter is $615.48, and a 4-inch meter is $1,100.52 before usage, fireline, sewer, or other charges.

Why sewer class matters more than the headline rate

Hayward sewer rates can vary dramatically by use. With a separate irrigation meter, July 2026 non-residential sewer rates include $8.91 per CCF for all other domestic use, $11.80 for restaurant with grease interceptor, $14.52 for restaurant without grease interceptor, $10.13 for commercial laundry, and $28.81 for food manufacturing.

Without a separate irrigation meter, the July 2026 schedule lists lower per-CCF factors for many categories, such as $8.02 for all other domestic use and $13.06 for restaurant without grease interceptor. That difference is a signal to review how irrigation and sewer billing are separated before modeling any usage-reduction project.

What a 20 percent usage reduction could mean

Directional estimate: assume a Hayward non-residential account uses 200 CCF per billing period and has separate irrigation, with sewer classified as all other domestic use. Water exposure is 110 CCF at $9.22 plus 90 CCF at $10.82; sewer exposure is 200 CCF at $8.91.

Reducing the account by 20 percent means 40 CCF less. At this usage level, the marginal combined water and sewer rate is about $19.73 per CCF, producing about $789.20 in variable exposure for that billing period before fixed service fees, fireline charges, critical-user charges, meter setup, site conditions, and installation feasibility.

What to check first on your bill

Confirm customer class, bi-monthly water CCF, meter size, fireline charges, sewer business classification, whether a separate irrigation meter exists, and whether the account is a coded user or a critical user.

Critical users require a different model. Hayward lists July 2026 critical-user components for flow, carbonaceous biochemical oxygen demand, and suspended solids, so a food, industrial, or manufacturing site should not use a standard domestic sewer model.

Where Smart Valve fits

Smart Valve may be relevant when a Hayward commercial property has meaningful controllable metered water volume and the site is technically qualified. It cannot reduce fixed service fees, fireline fees, or wastewater strength charges that are driven by pounds of pollutants rather than metered water volume.

The correct assessment starts with the water tier, sewer classification, irrigation meter status, and whether sewer follows water consumption for the account.
