HIDDEN TREE RANCH Water System

Inactive system

If you are a resident looking for your current water provider, see water systems in Lubbock County, TX.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Texas’s official records. Always confirm current status with Texas before making decisions based on this information.

System facts

System ID (PWSID): TX1520009
System type: Community Water System
Population served: 0

Ownership: privately owned
Water source: groundwater (wells)

HIDDEN TREE RANCH formerly served 0 people from groundwater.

EPA's federal records list this system as inactive in 2016; the record below is historical.

As of August 1, 2026, its federal record holds 117 entries between 1978 and 2016, all of which EPA lists as closed. Nothing has been added since 2016.

Of the 117, 74 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 inorganic chemicals, synthetic organic chemicals, and the Public Notice Rule and Revised PN Rule.
