Water Consumption

Water Consumption

Current Demand for Water

  • Regional municipal demand for water is greater than all other uses combined and includes city-owned utilities, public water districts, water supply corporations, or private utilities supplying residential, commercial (non-manufacturing businesses), and institutional water.
  • While the Water Use Survey is mandatory for public water suppliers, major manufacturers and utilities, it is voluntary and subject to error.

Current Demand for Water

Groundwater Availability

  • Long-term trends show an increasing transition from groundwater to surface water as a primary source for Central Texas (not shown).
  • Extended drought (Central Texas was under extreme/exceptional drought conditions from April 2011 to March 2012) will constrain both of these sources.
  • As a region, Central Texas is showing a sinking water table.

Groundwater Availability

Water Knowledge

  • Burnet and Hays County residents are most confident of their knowledge in the source of their water.
  • Region-wide, about 15% of Central Texans have “no idea” where their water comes from.

Concern About Water

Survey Question: Thinking about the amount of water in your community, would you say there is…

Conservation Effort Awareness

  • Generally, residents of urban counties are more aware of efforts and programs to conserve water in their communities. This may be a result of campaigns focusing on urban and suburban utilities and high-growth areas where current and future water use is and will be greatest.
Conservation Efforts Awareness

Survey Question: Are you aware of any efforts to conserve water in your community?


The ongoing drought has increased awareness of water consumption and conservation.


Central Texas residents and businesses manage water to ensure adequate and affordable long-term supplies and reduce demand for new water sources.


Water management is as important to the sustainability of our region as any other single concern. Access to water is not geologically distributed to match current growth and consumption patterns, which drives demand for large infrastructure projects. Greater effort is needed to prepare the region for possible
extended drought.
