What changed in Santa Clara
Source-reported facts: Santa Clara published proposed 2026-2027 water, sewer, and recycled-water rates for a June 9, 2026 public hearing. The page says the City serves about 26,000 service connections, including both residential and commercial customers.
The proposed potable water rate is $11.09 per HCF, compared with the current $9.89. Santa Clara says water purchasing, infrastructure maintenance, conservation-related revenue pressure, and wholesale supplier increases are key drivers.
Who may be affected
Commercial properties in Santa Clara should pay close attention because sewer charges vary by non-residential type. The proposed schedule lists restaurants at $23.48 per HCF, food and kindred products at $23.23, hotels and motels at $9.19, hospitals at $8.30, and repair shops and car washes at $7.64.
The page also describes recycled water use by commercial and industrial customers for irrigation, dual plumbing, industrial processes, cooling, and manufacturing. Recycled water is proposed at $6.05 per HCF.
Why the sewer classification can dominate the bill
A Santa Clara restaurant account is not exposed to the same sewer rate as a hotel, school, hospital, laundry, car wash, or other non-residential account. That classification must be confirmed before any savings estimate is credible.
For some business types, the sewer rate is higher than the proposed potable water rate. That means an analysis that only looks at water consumption can materially understate the operating expense at risk.
What a 20 percent usage reduction could mean
Directional estimate: assume a Santa Clara restaurant uses 200 HCF per month and the same HCF volume is relevant to water and restaurant sewer charges. A 20 percent reduction equals 40 HCF.
At $11.09 per HCF for water plus $23.48 per HCF for restaurant sewer, those 40 HCF represent about $1,382.80 in monthly variable exposure. Actual savings depend on wastewater discharge assumptions, customer class, fixed charges, recycled-water use, and installation feasibility.
What to check first on your bill
Confirm customer type, billed HCF, water meter size, minimum monthly water charge, sewer classification, recycled-water meter, fire service charge, and cross-connection charge.
Commercial and industrial customers should also check whether major-user operating and maintenance cost recovery or annual capital cost recovery lines apply before modeling payback.
Where Smart Valve fits
Smart Valve may be relevant when the property has controllable potable-water use and sewer charges are connected to the same usage pattern. It should not be presented as reducing fixed fire-service, cross-connection, or non-usage charges.
The right first step is to review 12 months of bills and classify the account by business type before estimating a 20 percent usage-reduction scenario.
What to Do Next
Verify the non-residential sewer type before using any blended sewer rate.
Separate potable water, recycled water, fire service, and cross-connection charges.
Model restaurants and food-service accounts separately from offices or hotels.
FAQ
What is Santa Clara proposed 2026-2027 potable water rate?

Why are Santa Clara restaurant sewer rates important?
Santa Clara lists proposed restaurant sewer at $23.48 per HCF, which is higher than the proposed potable water rate and can dominate the variable bill.
Can recycled water change the savings model?
Yes. Recycled water is listed separately at a proposed $6.05 per HCF and should not be mixed into a potable-water reduction estimate without checking the meter and end use.
