Wimberley ISD's One Water School -

Blue Hole Primary


  • Category: Educational/Governmental
  • Organization Location: Wimberley, Texas
  • Activity: Rainwater harvesting used as part of an integrated approach to water management.


Wimberley ISD approached design and construction of the primary campus using the One Water concept which looks at drinking water, wastewater, stormwater, and greywater as a single resource. The campus collects and stores rainwater and air conditioner condensate for toilet flushing and landscape irrigation through an advanced reuse system. Estimates show that the system can reduce the campus water consumption footprint by approximately 90 percent.
