Do Texas Cities Use Property and Sales Tax to Fund Water and Sewer Departments?
Short answer: In a appropriately operated Texas city, no. Neither property tax nor sales tax should fund the day-to-day operations of the water and sewer department.
The Core Principle: Enterprise Funds
Texas cities almost universally operate water and sewer as an enterprise fund. Under GASB standards, an enterprise fund is designed to be self-supporting through user charges — rates, tap fees, and connection fees — rather than tax dollars. It is meant to operate like a business: revenue from customers covers the cost of service.
General taxes flow into a different lane entirely:
Property tax → the general fund, which covers police, fire, streets, parks, and administration.
City sales tax (general 1%) → also the general fund, same lane as property tax.
The two systems are meant to stay separate. The cleaner the separation, the healthier the utility.
Dedicated Sales Taxes Are Fenced Off Even More Tightly
Texas caps local sales tax at 2% on top of the state's 6.25%. Much of that 2% is legally earmarked and cannot touch water/sewer operations:
Type A / Type B EDC sales tax — restricted by Local Government Code Chapters 501–505.
The Legitimate Crossover Points
There are only a few places where tax dollars can properly intersect with the utility — and all of them are capital, not operating support:
GO or combination (tax-and-revenue) bonds (debt) backed by the ad valorem pledge can fund water/sewer infrastructure. Many small cities use these because they price better than pure revenue bonds. This indirectly puts property tax capacity behind utility capital.
A narrow EDC infrastructure project can fund water/sewer infrastructure as a qualifying project under specific statutory findings; to fund the economic purpose of creating or expanding jobs— but this is a capital project, not a way to keep rates low.
Transfers Often Run the Other Direction
In practice, money frequently flows from the utility to the general fund — as a return on investment, a payment in lieu of taxes (PILOT), or a franchise-equivalent fee. This is legal and common, but it functions like a hidden tax on ratepayers and should be documented and reasonable.
The Practical Takeaway
If the utility cannot cover its own operations, maintenance, debt service, and capital replacement out of rates, that is a rate-setting problem to solve directly — not something to quietly backfill from property or sales tax revenue. When the general fund has to subsidize the utility, it usually means rates are set below the true cost of service.
A genuinely healthy enterprise fund stands on its own.
