TOWN OF SUNNYVALE is one of 817 community water systems in Texas in the 3,301 to 10,000 people size category, serving 8,839 people from surface water.

As of August 1, 2026, its federal record holds 11 entries between 2004 and 2017, all of which EPA lists as closed. Nothing has been added since 2017.

Of the 11, 9 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Stage 1 Disinfectants and Disinfection Byproducts Rule and the Consumer Confidence Rule.

It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits.
