Revenues by Source

The Utility Fund's revenue primarily comes from charges for services. Over 80% of the operating revenue is tied to
volumetric charges, which are a pass-through from the Trinity River Authority (TRA). This portion of the revenue
uctuates based on TRA’s rates and customer water usage, making it largely outside the City’s direct control. The
remaining portion of operating revenue comes from xed monthly base charges for water and wastewater services,
which cover the City’s operating costs. Additional minimal revenue sources on the operating side include tap fees,
installation fees, and penalties for late payments.

On the capital side, the primary revenue source is the dedicated capital project fee, which ensures consistent funding
for infrastructure improvements and system upgrades. In addition, transfers from the operating side of the fund
provide supplementary funding for capital projects. Although the City collects some revenue from impact fees, these
play a relatively small role compared to the capital project fee and operating transfers.

Investment income from fund balances, though minimal, contributes small amounts to both the operating and capital
sides of the Utility Fund.
