Regional Planning

As part of securing adequate water for our communities, SARA has participated in extensive planning with others in the region facing similar needs.


SB1 CommitteeIn 1997, the Texas State Legislature approved Senate Bill 1 to meet the State’s water needs through 2050. SB1 created 16 planning regions and mandated the creation of regional water plans. SARA was selected to serve as the program manager for Region L, also known as the South Central Texas Region, comprised of 20 1/2 counties including SARA’s four-county region.

The South Central Texas Regional Water Planning Group, comprised of water users, environmental groups, government entities and the public, of which SARA is a member, has been working for the past ten years on the Region L water plan which must be updated and resubmitted every five years. In January 2006, the group approved a plan to submit to the Texas Water Development Board (TWDB) that identified water resource options with the potential to meet the major demands through 2060. The Texas Water Development Board adopted the 2007 State Water Plan on November 14, 2006. Current Region L efforts focus on development of the 2011 Regional Water Plan.

RWA (Regional Water Alliance):


To promote and facilitate the sharing of ideas, knowledge, experience and resources with the end goal of developing collaborative water projects.


The Regional Water Alliance, created in 2006, represents 19 local water purveyors and regional water entities. Each water purveyor and regional water entity’s governing body executed an interlocal agreement pledging to assist each other with:

  • Assessing and developing water supply options on a regional basis;
  • Promoting regional conservation and reuse of water resources;
  • Working together to realize region-wide efficiencies and economies of scale in the development, distribution and operation of water projects for the mutual benefit of a diverse customer base and;
  • Advancing a synergistic alliance among water agencies to jointly investigate funding opportunities, influence state and federal water regulations and policy, conduct study efforts and support a common voice in water issues facing the region.
In 2010, RWA will be offing Water Planning workshops to existing members and possible new members with creating water management plans to better manage water resource within the San Antonio River Basin.

RWRDG (Regional Water Resource Development Group) Purpose:

The Regional Water Resource Development Group (RWRDG), administered by the San Antonio River Authority, is a cooperative purchasing/lease program that acquires Edwards Aquifer groundwater withdrawal rights for municipal use. The program provides several communities access to Edwards Aquifer groundwater by pooling together to create a competitive market for the buying and selling of water rights, maximizing the buying power of each partner, simplifying the administration and implementation of water right transfers, reducing duplication of staff efforts and minimizing competition between cities and water purveyors, and providing one contract for individuals interested in selling or leasing water.
