- City owned wells obtain water from the Trinity Aquifer
Guadalupe-Blanco River Authority (GBRA)

by contract Fair Oaks Ranch Utilities manages and operates groundwater pumps from the Trinity Aquifer, four Water Treatment Plants, and a distribution system to deliver water to residents. Treated water is also purchased from the Guadalupe-Blanco River Authority (GBRA) and mixed with the treated groundwater.

This area relies on rainfall that then feeds into the natural aquifers, lakes, rivers, etc.; consequently, this area is prone to droughts when rain is scarce.  Responsible water use is encouraged to ensure that current and future residents of the City have a safe and adequate water supply for domestic use, sanitation and fire protection. Do your part and be water conscious.
