Houston Commercial Water & Sewer Rates: 2026 and History Since 2020
Your guests, tenants or staff do not have to use an extra gallon for the water-and-sewer expense to grow. Houston’s higher commercial usage rates make the same billed volume cost more. For an owner, that means more money going toward the same everyday operation—and a stronger reason to look for a lasting reduction in the bill.
The selected rate
What does water and sewer cost in Houston?
$21.14 per 1,000 gallons for the selected usage-price reference, effective Apr 1, 2026. View the utility’s current schedule.

How this example is calculated
Gallons ÷ 1,000 × the selected combined price per 1,000 gallons. Volume is held constant; no savings, annual usage, inflation adjustment, or installation cost is assumed. These are selected snapshots, not a complete annual history. Example charges are rounded to cents before their difference is calculated.
More of the budget goes toward the same everyday work
Water supports the routines that keep a commercial property useful: guest rooms, restrooms, kitchens, cleaning and other operations. When the rate rises, those same routines can cost more even with careful control of consumption.
The fixed-volume example makes that pressure visible. It holds the selected water and sewer quantities steady, then applies the 2020 and current commercial prices. The difference is extra expense for the same billed gallons, before considering the rest of the account’s charges.
Start with the service your property actually pays for
This reference covers City of Houston commercial service inside city limits. Confirm that provider and classification on your bill. A Houston-area mailing address alone does not establish which tariff applies to the building.
The fee schedule separates usage prices from meter-size base charges and identifies an additional TCEQ fee on the water entries. Check the sewer-billed quantity as well. Once those pieces are clear, a proposed reduction can be evaluated against the expense the owner actually carries.
Where Flumera fits
How Flumera can help protect your operating budget
For a Houston commercial owner, a recurring water saving can create room elsewhere in the operating budget. Flumera focuses the review on the building’s incoming water service, using the actual commercial account and billed quantities to evaluate the opportunity.
Flumera’s valve is designed to compress entrained air in the water service line. Where entrained air affects meter registration, addressing it may create an opportunity to reduce billed volume. The site assessment reviews your utility bills, meter and pipe details, and operating conditions to establish whether the valve is a suitable fit.
We use your building’s inputs to model savings, equipment cost and payback. That gives you a property-specific decision to evaluate before committing to an installation.

Start with the bill you are paying today
- Confirm City of Houston service, inside-city status and the billed commercial class.
- Separate water and sewer volume charges from each meter-size base charge.
- Confirm sewer-billed quantity, TCEQ fees, drainage and any account adjustments.
- Compare billed quantities and operating conditions before attributing the entire increase to the tariff.
These details help turn a rising expense into a savings plan you can evaluate against the property’s actual operating costs.
Common questions
Are these rates valid everywhere in the Houston metro area?
No. This reference is for the stated City of Houston inside-city commercial class. Check the provider and account classification on each property’s bill.
Is the combined figure a complete Houston commercial water bill?
No. It combines the selected water and sewer volume charges. Meter-size base charges, fees, drainage and account-specific adjustments are outside the comparison.
Does a higher rate mean a building will save more water?
No. A rate changes the cost of a billed unit; it does not establish an achievable reduction. A property assessment must verify the account, volume baseline, meter conditions and operating scope.
