What changed in San Luis Obispo
Source-reported facts: San Luis Obispo says City Council adopted updated water and sewer rates for FY2025-26 and FY2026-27 on June 17, 2025, with new rates taking effect July 1 of each fiscal year.
For July 1, 2026, the city lists non-residential water at $11.29 per CCF and non-residential sewer at $11.65 per CCF. One unit equals one CCF, or 748 gallons.
Who may be affected
The immediate commercial audience is any San Luis Obispo account in the non-residential class: restaurants, hotels, offices, retail centers, car washes, laundries, healthcare facilities, schools, industrial users, and mixed-use properties.
The city also lists multi-family, non-residential, and landscape irrigation base fees by meter size. A 2-inch water meter base fee is $179.53 in FY2026-27, and a 2-inch sewer base fee is $148.25, before volume charges and applicable taxes or surcharges.
Why sewer is the commercial issue
San Luis Obispo explains that sewer usage is not billed by tier. The per-unit sewer rate applies to all water usage up to the sewer cap for residential and multi-family accounts.
The commercial distinction is important: the city states that non-residential accounts do not have a sewer cap and are billed for each unit of water usage. Commercial and industrial customers can install a separate landscape meter to avoid sewer fees on irrigation use, at the customer expense.
What a 20 percent usage reduction could mean
Directional estimate: assume a non-residential San Luis Obispo account uses 250 CCF per month and the water volume also drives sewer volume. The FY2026-27 variable water plus sewer rate is $22.94 per CCF before the 5 percent utility users tax on the water portion and before fixed base fees.
A 20 percent usage reduction on 250 CCF equals 50 CCF. At $22.94 per CCF, that is about $1,147 per month in variable water and sewer exposure. This is not a guarantee because actual savings depend on the bill, meter setup, irrigation separation, site conditions, and installation feasibility.
What to check first on your bill
Pull the current bill and record customer class, meter size, water CCF, sewer CCF, water base fee, sewer base fee, water-system access charge if present, utility users tax, and any separate landscape meter.
If irrigation is included on the domestic meter, evaluate whether a separate landscape meter or operational irrigation reduction could reduce sewer exposure. If usage has changed, separate the July 2026 rate effect from leaks, occupancy, process water, laundry, cooling, or landscape schedules.
Where Smart Valve fits
Smart Valve may be relevant when a meaningful share of the San Luis Obispo bill is tied to metered water volume and site conditions support installation. It cannot reduce fixed base fees, taxes that apply to fixed lines, or charges unrelated to usage.
The useful next step is a bill assessment that models actual CCF, meter size, sewer linkage, landscape-meter options, and a range of possible usage reductions against the July 2026 rate baseline.
What to Do Next
Confirm whether the account is non-residential, multi-family, or landscape irrigation.
Separate fixed water and sewer base fees from CCF-linked charges.
Check whether irrigation is creating avoidable sewer exposure on a non-residential bill.
