The plan identifies both short and long-term water supply needs and recommends water management strategies for addressing them. The plan is updated every five years.

The SCTRWPG is composed of planning group members representing various interest groups. It is guided by the Texas Water Development Board, led by an Executive Committee, governed by by-laws, and supported by the San Antonio River Authority and a team of technical consultants. Planning group meetings are held on a quarterly basis.
