Current Water Supply Projects

Current Water Supply Projects

Affordable. Sustainable. Diversified.

Just a few years ago, San Antonio was totally dependent on day-to-day pumping from the Edwards Aquifer for the city's water needs. Now, as a result of extensive planning and funding through the Water Supply Fee, SAWS is working to secure San Antonio's water future.

SAWS is moving forward with water supply projects that provide ratepayers with the most viable and affordable options to secure current and future water supplies. These project recommendations are outlined in the 2012 Water Management Plan. The plan, which includes population projections, per capita consumption estimates, aggregate demand forecasts and supply development options, outlines strategies to:

  • Provide adequate water supplies, even during critical drought periods.
  • Postpone dependence on more costly resource supplies.
  • Promote greater use of non-Edwards Aquifer supplies in the long-term.
  • Recognize the reality that future supplies must be affordable.
